Description

Method and device for controlling desktop background

Technical Field

The invention relates to the field of display control of computer equipment, in particular to the field of desktop background control of computer equipment.

Background

In a computer system, in order to facilitate the use of a user, shortcut links for starting various operating system functions and application programs are graphically represented and are placed on a screen of a computer display for display, corresponding application programs can be started or corresponding functions can be executed according to the operation of the shortcut links by the user, the shortcut links can also be represented by menu items or control buttons, the menu items or the control buttons can be directly displayed in the display of the screen or can be classified and displayed in a grading way, a picture displayed on the screen is called as a desktop of the computer system, and meanwhile, pictures can be set as a desktop background, so that the screen display is more colorful. The desktop background occupies most of the area of the desktop, the desktop is drawn on the desktop background in a shortcut mode, the desktop background is reasonably arranged, the desktop is attractive, users feel happy, and the computer is more humanized.

At present, a control method of a desktop background mainly uses an operating system to provide a desktop background picture replacement program for a user. As shown in fig. 1, the picture data is stored on the local disk in the form of a "background 2. jpg" file, specifically located on the local disk "C: under the directory of \ my document \ my picture \ my desktop \ directory, "my document", "my picture" and "my desktop" are respectively the directory names of the first, second and third level directories under the C-disk, under the third level directory "my desktop", a plurality of picture files are included, if the background 2.jpg "is to be set as the desktop background, the first, second and third level directories must be selected in sequence, and the required picture can be selected and set as the desktop background only by entering step by step.

For example, in a windows xp operating system, to select a picture file "background 2. jpg" as a desktop background, it is necessary to select an "attribute" item of a menu item selected in a right-click menu of a desktop first, select a "background" option page in an open dialog window, select a "browse" button, open a file selection dialog box, sequentially select and open a local disk D, a "my document", "file", "picture" and a "my desktop" directory in the dialog box, then select a list of picture files that can only be displayed in the file selection dialog box, select a "background 2. j" file in the list, select a "ok" button, then need to select a display effect of the picture, which may be set to be tiled, centered or stretched, and finally select a "ok" button, and set the selected picture as the desktop background.

The disadvantages of this method are: when the desktop background is switched every time, a user needs to select a corresponding directory for searching for the picture file for many times, so that the steps are complicated, and the efficiency is low; when the picture is selected, the picture is selected according to the picture file name through the display attribute dialog box, and the operation is not intuitive; when the number of the catalogues and the files is large, the user needs to try one by one when the user wants to find a favorite file as a background, and the operation speed is low; when the picture is used as the desktop background, only a part of the picture may be displayed for a larger picture, and the picture display may be obviously deformed for a picture with a larger difference with the desktop length-width ratio, so that the display effect of the picture cannot be well controlled by the method.

Therefore, the existing desktop background control method has the problems of low operation efficiency, non-intuition, inconvenience and incapability of well controlling the display effect.

Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

The embodiment of the invention can be applied to a computer device using a windows XP operating system, but is not limited to the method, and persons skilled in the art can easily understand that the invention can be applied to any computer device with a display and a processor. Generally such a computer device, as shown in FIG. 2, includes a main memory 201 coupled to bus 200 for storing data and instructions, and formed of Random Access Memory (RAM) or other dynamic storage; a processor 202 coupled to bus 200 for executing instructions in main memory; a Read Only Memory (ROM)203 coupled to bus 200 for storing static information and instructions for processor 202; storage device 204, coupled to bus 200, may store additional information and instructions, and may employ media such as magnetic, optical, or magneto-optical disks. A display 205, coupled to bus 200, for displaying program information may employ devices such as a Cathode Ray Tube (CRT), Liquid Crystal Display (LCD), and the like. An input device 206, coupled to bus 200, for entering information, may include alphanumeric and other control keys. Another user input device may be provided, such as a cursor control, a mouse, a joystick, a trackball, or cursor direction keys, a touch screen, a stylus, a wireless remote control, etc. computer pointing device 207 may also be provided, and may transmit direction information and key commands input by a user to processor 102 and may control a cursor on display 205 to move. Computer pointing devices typically have two degrees of freedom in two axes (e.g., x, y) that can specify positions in a plane. A communication interface 208 coupled to bus 200 for receiving and transmitting data information, computer devices connected to a local area network 209 through communication interface 208, local area network 209 connected to a host 210, and also connected to an internet service provider 211 and to the internet 212 through internet service provider 211. The computer device runs by fetching an instruction from the main memory 201 by the processor 202, executing the instruction, reading or writing data according to the requirement if the instruction needs to input or output data, and fetching a next instruction after executing the instruction. Hardware circuitry employed in connection with the present invention may be replaced with software instructions or a combination of hardware and software instructions and embodiments of the present invention are not limited to any specific combination of hardware circuitry and software.

With the above features as the determination criteria, a mobile device such as a PDA, a mobile phone, a digital tv set-top box, a notebook computer or a PC having the above features can be regarded as a computer device.

Taking windows xp as an example, a typical layout of a desktop is a desktop window 101, a desktop background 102 and a shortcut 103 as shown in fig. 3, the desktop background is divided into 2 main areas, namely a shortcut area 104 and a blank area 105, in order to show the range of the shortcut area 104 and the blank area 105, an area boundary 106 which does not exist is schematically drawn in the figure for convenience of description, and a task bar 107 is also included in the figure for taking charge of task scheduling and switching, and a "start" button 108 is used for calling up more start links in a menu mode. The desktop background 102 is a picture overlaid on the desktop window 101 (the picture may also be dismissed by the user and replaced with a monochrome background). For most users, the number of icons on the desktop will occupy no more space than 1/3 of the total area of desktop space.

Some operating systems also support multi-desktop switching. For example, a linux operating system has 4 desktops which can be switched arbitrarily by a user, and windows xp, although not directly providing multiple desktops, provides a programming interface for creating multiple desktops.

For the improvement of the visual effect of the desktop, the operating system provider and the third-party software provider all make continuous efforts, such as a 3D desktop window (the desktop window is arranged in a 3D manner, so as to improve the use experience of the user) or a desktop plug-in auxiliary tool (such as a desktop clock, a desktop news reader, and a desktop search provided by "Yahoo | widget Engine", "google desktop", and the like), which contribute to the improvement of the use experience of the user of the computer, but lack a solution for the quick and efficient setting of the desktop background.

In addition, a virtual desktop software is also provided in the third-party software, and the virtual desktop software has the characteristic of supporting the creation of a plurality of desktops. Similar to the purpose of multiple desktops provided by an operating system, the main function of a virtual desktop is to provide more flexible application program shortcut grouping management to meet different working environment requirements, a user can perform different works on different virtual desktops and can switch between different virtual desktops at any time, for example, the user creates 2 virtual desktop settings by using certain virtual desktop software, a virtual desktop a mainly based on an entertainment function mainly provides program shortcut links of multimedia entertainment functions, a virtual desktop B mainly based on the work mainly provides program shortcut links of office software, and the user can switch to the virtual desktop a when using the virtual desktop B to go to work at work. Desktops described herein also include the case of such virtual desktops. The virtual desktop can be a stand-alone replacement program for the desktop control function of the complete operating system, or a function extension program based on the desktop function of the existing operating system.

The following describes the subclassing of the windows XP operating system default desktop and the implementation of the process of the present invention.

In the existing windows XP operating system, the desktop does not provide response to the selection of a mouse in a background area of the desktop and the operation of a roller, and the invention can be implemented by taking over the response process of the desktop to a message and then using a code to respond according to the operation of the mouse so as to control the output effect of the desktop. The invention intercepts the human-computer interaction message of the desktop by subclassing the desktop, and calls an API (application programming interface) when receiving a specific message after analyzing and filtering the message to realize the operation of the desktop display content and the control of the desktop display process. The invention completes the control of the desktop through the cross-process sub-type of the desktop window, intercepts the information of the desktop window and realizes the display control and the interactive operation on the background area of the desktop. Fig. 4 shows a flowchart of the process of subclassing the desktop, which specifically includes: firstly, a system hook function is installed, a subtype message is sent to a resource manager, the message triggers the system hook function, an operating system automatically loads a DLL (dynamic link library) containing the hook function to a resource manager process, then the hook function is executed, the system hook function responds to the message, and the subtype of a desktop window is completed. In order to avoid affecting the system performance, DLL reference can be added to keep DLL in the resource manager process after the operation of subtype is completed, and the system hook is cancelled. The interception of desktop messages and the integration of processing codes and the desktop are completed, and the processing codes can receive operation information of a keyboard, a mouse or other computer pointing equipment of a user on the desktop and respond to corresponding messages.

Referring to fig. 5, it is a flow chart of method embodiment 1 of the present invention, including:

step 501, a link icon is set on the desktop, and the link icon is used for pointing to a picture file which is saved in a storage unit and serves as a desktop background.

In order to make the description more intuitive, in the embodiment, the desktop background file mainly uses a picture file, and the appearance of the link icon mainly uses a thumbnail.

According to a picture file which is preset by a user and is to be set as a desktop background, a link address of the picture file is obtained, a link icon is generated by matching with a preset display style, and the link icon is drawn on the desktop. Because the sub-type operation of the desktop is carried out in advance, the mouse and keyboard messages can be processed, when the link icon is judged to be selected or operated, the response to the operation can be realized by the code, and the corresponding processing is carried out.

The pictures to be set as the desktop background may be located in any directory on the local hard disk, or may be all picture files in a specified directory, for example, a directory "C: all picture files under \ my document \ my picture \ my desktop \ are used as picture files to be set. The picture files can be locally available, downloaded from a network to a local cache directory, or stored on the network. The directory for storing the picture files may contain multiple levels of subdirectories, and whether the picture files in the subdirectories need to be acquired or not can be set in advance by a user. There are two methods for specifying the location of a picture file: firstly, a directory is appointed, all picture files in the directory are files to be set, and secondly, a certain picture file under the directory is appointed to be used as a file to be set, and the picture file and the file can be combined for use. Multiple sources of picture files may be specified simultaneously.

According to the source of the picture file designated by the user, a link icon pointing to the picture file can be generated, the link icon object can comprise a display attribute and a pointing attribute, the display attribute specifies the display style of the link icon, the link icon can be displayed as a figure, a symbol or a character and a combination of the figure, the symbol or the character, and the link icon object can also be displayed in a hidden manner on the display style, such as being displayed in a transparent manner, in the case, the link icon can be selected by the user or can be clicked by using a computer pointing device such as a mouse and the like although the link icon is invisible; the pointing attribute specifies the location information of the picture file pointed by the link icon, and the location information may be a path and a file name of the picture file, or other types of location information, such as a URL.

The number of the link icons can be multiple, the link icons can be used as a layer to be placed on a desktop for display during display, the desktop can be regarded as a mode that a shortcut layer and a desktop background layer are overlapped, and preferably, the layer of the link icon can be placed below the desktop background layer. The following lists several optional hierarchical relationships: as shown in fig. 6a, the position diagram of the layer is sequentially from top to bottom: the desktop background layer is possibly covered by the pictures of the link icon layer and the shortcut layer; the link icon layer can also be placed at the lowest layer, as shown in fig. 6b, from top to bottom: the desktop background layer is not covered by the pictures of the linked icon layer, when the background pictures occupy the whole desktop background layer, the linked icon layer is covered, and when the background pictures are slightly smaller than the whole desktop background layer, the linked icon layer is partially visible; the desktop background layer can be further additionally provided with a link icon background layer which is used as a background layer of the link icon, when the desktop background layer is not provided with a background picture, the background of the whole desktop is displayed as a picture of the link icon background layer as a background, as shown in fig. 6c, the shortcut icon layer, the desktop background layer, the link icon layer and the link icon background layer are sequentially arranged from top to bottom and can be separately arranged, the two can be simultaneously displayed, the background picture of the desktop background layer of the original desktop covers the link icon layer and the link icon background layer, and when the desktop background picture is large enough, the link icon layer and the link icon background layer are not visible because of being completely covered. When the link icon layer is covered or hidden, the link icon layer can be activated or displayed through a preset command for the user to operate. The selectable hierarchical control method comprises the following steps: when the desktop is drawn, the required hierarchical relation can be expressed by controlling the drawing sequence through codes, and a specific layer can be encapsulated in an interface element such as a window, and then the required hierarchical control target is achieved by controlling the hierarchy of the window.

Preferably, the link icon may be a thumbnail of the picture file, a symbol icon or a text mark, and a combination thereof. When the thumbnail of the picture file is displayed, the thumbnail of the picture file needs to be generated in advance according to the picture file data, and the generation method can be calling a thumbnail generation function provided by an operating system, or rewriting codes to read the data of the picture file, obtaining the thumbnail according to a certain sampling algorithm, and storing the thumbnail in a data structure of a link icon as an attribute value of the link icon. The method can enable the user to conveniently preview the approximate content of the picture file, and is convenient for the user to purposefully select the needed picture as the desktop background. The link icon may also be displayed as a specific symbol, such as a symbol representing an image, and further, may be displayed as a symbol representing a picture file type. Such as graphic marks of GIF or JPG pictures, etc., can allow a user to recognize information such as the type of picture file. Of course, the link icon may also be displayed as a text label, such as a text message as "picture". The link icon may also be transparent and not visually displayed, but actually occupies a certain display space, which may prevent the link icon from obstructing the desktop background.

Preferably, the thumbnail may be a thumbnail of a complete image or a thumbnail of a portion of an image of the picture file. When the complete image data is taken to form the thumbnail, the general view of the whole picture can be seen in the formed thumbnail, so that a user can conveniently preview the general content of the picture, but the details can not be seen clearly, and only a part of the picture can be taken to form the thumbnail, so that the details in the picture can be better displayed in the thumbnail; when a part of the picture is taken, the central area of the picture with a fixed size can be taken, and the area beside the picture can also be taken, for example, the local picture at the upper left corner of the picture can be taken, and the local picture can be square or circular.

The placement location of the link icon may be anywhere on the desktop. Preferably, in the windows xp computer operating system, the shortcut icon is generally placed on the left side of the desktop, in which case, the desktop may be divided into a shortcut area and a blank area according to a portion of the desktop occupied by the shortcut icon, and the link icon of the present invention may be placed in the blank area. By using the mode for displaying, the link icon and the desktop shortcut icon are respectively displayed at different positions, so that the link icon and the desktop shortcut icon are prevented from being mutually covered or mutually staggered, and the visual appearance is clearer. Preferably, the link icon can be placed in any window, and for convenience of operation, the link icon is placed in a desktop floating window, in windows xp, typical desktop floating windows are two, one is a desktop sub-window which is always located below other application windows, the other floating window can be located at the top layer (or not) when displayed but can be hidden when not used, the floating window is activated at the edge of the screen through a mouse, normal work of a user cannot be influenced, and the window activated at the edge of the screen can be a window which is reduced at the edge and slides out from the edge in an amplifying mode, or can be a window which is directly displayed on the screen. The floating window set as the desktop child window and the floating window placed on top may remain constant all the time while the operating system executes the "show desktop" command to automatically minimize other application windows. Floating windows are common in some desktop tools, such as Microsoft Vista operating system and "Yahoo! The Widgets Engine and Google Desktop provide auxiliary tools running on the Desktop, such as clock programs, news browsers, mail notification tools and the like, and timely communication tools such as Tencent QQ also utilize the Desktop floating window. In this embodiment, when a floating window is used as a thumbnail container, preferably, the floating window in the form of a desktop sub-window that does not occupy a working space may be preset with one or more windows, for example, a windows xp operating system, a window may be created on a desktop as a desktop floating window through CreateWindow (creating a window) or CreateWindowEx (creating a window with an extended style parameter) system function, the desktop floating window is also a part of the entire desktop, and unlike a common window, from the overall logic, the desktop floating window is a part of the desktop, in this embodiment, when link icons are displayed in the floating window, all link icons may be displayed in one floating window or in multiple floating windows, a specific display mode is set as required, and the floating window may be moved to any place of the desktop by a user as required, the user may autonomously arrange the arrangement of the desktops. Of course, the floating window displaying the link icons can be maximally displayed on the background of the whole desktop, so that more link icons can be displayed at one time, and when the number of the link icons is large, a user can conveniently select the required link icon without page turning operation. A common window can also be created to serve as a connecting icon container, and the property of the common window can be improved to have the characteristics of the desktop floating window. In order to enable the display effect of the link icons to be more coordinated with the desktop, the floating window can be set to be in a borderless and transparent background style, and the floating window can be better fused with the desktop.

Preferably, the link icon can be displayed in a fixed row and column mode, a size gradient mode or a stack mode. When the link icons are displayed in a fixed row-column mode, the range of the display area needs to be preset or acquired, and the display size of the link icons needs to be preset, of course, in order to keep consistency of desktop display effects, the link icons can be the same as the desktop shortcut icons, and the size of the link icons can be slightly larger, so that larger link icons can be provided for a user to recognize and check conveniently, then certain blank intervals are increased according to the size of the display area and the size of the link icons, the number of icons to be arranged in each row is calculated, the link icons are displayed row by row, and the link icons can be conveniently browsed by the user through the mode display, and are not mutually shielded, so that the user can conveniently select. The mode of gradual change of the size can be used for displaying the link icon, in this way, the currently selected link icon is displayed in an enlarged state, the enlarged size can be set according to specific needs, for example, the enlarged size can be set to be 2 times of the original size of the link icon, the link icon positioned around the enlarged displayed link icon can also be enlarged in a slightly smaller size (such as 1.5 times of the original size) for display, other link icons far away are kept to be not enlarged for display, so that the link icon has a transition effect on the display, the visual effect is better, the judgment and the selection of a user are facilitated, meanwhile, the enlarged behavior can be associated with the cursor of the pointing device of the computer, the link icon at the position where the cursor of the pointing device of the computer is positioned is enlarged, and the enlarged link icon is switched along with the movement of the cursor, in specific implementation, a message mechanism of an operating system can be adopted to intercept and acquire the position of the cursor, judge the link icon on the position, enlarge and display the link icon, and enlarge and display the surrounding link icons in a smaller proportion, so that a user can more clearly view the information of the link icon to be selected. The link icons can also be displayed in a stacked mode, for example, the link icons can be arranged in a partially overlapped mode and arranged in a rotatable ring, when the link icons need to be selected, the ring-arranged link icons can be moved by using a computer pointing device, so that the needed link icons rotate to the forefront and are selected, and in the mode, more link icons can be placed for selection under the condition that the occupied desktop area is small, and the better display effect is achieved.

Preferably, when the number of the link icons is larger, the page display can be performed. The control can be performed according to the number of each page display preset by the user, and the specific control mode and the controlled effect can be realized and thought by those skilled in the art, and are not described herein.

Preferably, when the number of the link icons required to be displayed per page is greater than the display number that can be accommodated in the current display area, more link icons are displayed on the current page in a scrolling screen manner, and the operation of scrolling the screen can be controlled by a device such as a wheel of a computer pointing device (e.g., a mouse), or can be controlled by a page up/down key of a keyboard.

Preferably, when the current screen scrolling operation is performed by using equipment such as a roller of the computer pointing device, the stepping speed of the scrolling screen can be dynamically adjusted according to the position of the cursor of the computer pointing device on the screen, and the method has the advantages of strong controllability and intuitive stepping effect.

Step 502, receiving a selection of the link icon, and setting the picture file pointed by the link icon as a desktop background picture.

After executing the subclassing operation on the windows of the windows XP desktop according to the method, the method can intercept the operation and the state information of the pointing equipment (such as a mouse) of the computer on the desktop, and can trigger the program codes to carry out the predetermined processing when detecting the specific operation and state by analyzing the state information. For example, when the click operation of the computer pointing device is intercepted, the current coordinate of the cursor of the computer pointing device is obtained, the judgment is carried out according to the display position of the link icon, the click operation of the computer pointing device on which link icon is executed is judged, the pointing attribute of the link icon is obtained, the corresponding picture file is found, the picture file is opened, the picture data is read, and the picture data is written on the desktop background, so that the operation of setting the desktop background is realized. When the position of the cursor of the pointing device of the computer is not on any link icon, the message is sent to the original desktop message response processing code for processing, and the user may click a shortcut icon. The above operations of determining the operation of the computer pointing device, obtaining the picture file data, and writing the data on the desktop can be implemented in another way, and are not limited to the above method.

In this step, the selection of the link icon may also be automatically implemented instead of the selection of the link icon by the user, for example, when the desktop is started, a default link icon may be selected, and the picture file pointed to by the default link icon is used as the desktop background; or the desktop background picture can be set according to a prestored link icon selected last time as a default selection.

Preferably, the setting of the picture file as the desktop background in this step can be implemented by the following process: acquiring an image of the picture file pointed by the link icon; displaying the image on the desktop background. Various methods can be adopted in the specific operation of realization, namely, the data of the picture file can be directly written into the desktop background; or setting an image buffer area, writing the image into the buffer area, calling system functions to generate images of other parts of the current desktop except for the desktop background image, superposing the images to the image buffer area according to a preset mode, and replacing the content of the image buffer area into the desktop background; it is easily understood by those skilled in the art that any method that can implement setting the desktop background to the selected picture file can be adopted, and is not limited to the above two methods.

Preferably, the method further comprises receiving an operation command of a computer pointing device or a keyboard, and operating the background picture of the desktop. The invention can realize the control operation of various display effects of the desktop background picture, including the switching, scaling, local amplification, movement and the like of the background picture, and the control operations can be used by users, thereby enriching the display effect of the background picture, improving the controllability of the background picture and increasing the aesthetic degree of the desktop background.

Preferably, the operation on the desktop background may be:

when a page turning key of a computer keyboard or a preset specific key combination of a computer pointing device is pressed, the desktop background pictures are switched. When a user presses a page turning key or a specific key combination, the desktop after the sub-type operation intercepts the transmission of a message, the program judges that if the command is a predefined command for switching the background, a corresponding processing program is called for processing, a current background picture is obtained firstly, a next or previous picture file of the current picture file is obtained according to the command of the user, the image data of the picture file is read, and the image data is written into the desktop background, so that the picture switching is realized. Furthermore, when the picture file to be displayed is obtained, other pre-stored information such as the display proportion and the display position when the picture file is set as the desktop background last time can be taken out at the same time, and the display effect can be displayed according to the last time, so that the user only needs to set the display effect once for the picture file to be displayed, the picture file can be automatically displayed according to the last time setting mode when the picture file is used next time, repeated setting is not needed, and the use of the user is facilitated. The above processing procedure can be realized by other specific methods, and is not limited to the above method.

And when the roller of the computer pointing device is rolled, the background picture is enlarged or reduced on the desktop. The desktop intercepts the information of the roller operation and the current cursor position, calls a desktop background picture scaling function program after program judgment, firstly obtains the display proportion and path information of the picture file displayed by the current desktop background, reads the image data of the picture file, enlarges or reduces the image according to the user command, and writes the processed image data into the desktop background, thereby realizing the scaling operation of the desktop background. The above-described processing may be implemented by other specific methods, and is not limited to the above-described method.

When the local part of the background picture is selected, the selected local pattern can be amplified to the whole desktop background, and before amplification, the range of the selected local area can be adjusted in advance to enable the aspect ratio of the local area to be consistent with the aspect ratio of the desktop, so that after the local area is amplified to the whole desktop background, the picture is not deformed to be displayed.

And when the roller of the computer pointing device is pressed down and moved on the background picture, moving the desktop background picture.

Preferably, when the desktop background is reduced, a threshold value of the minimum size is preset, when the reduced desktop background picture reaches the threshold value, the step of reducing and displaying the desktop background picture on the desktop is automatically circulated for a plurality of times, the desktop background picture is automatically reduced until the preset size is reached, for example, the preset size can be set to be equal to the size of the link icon, under the condition, when the automatic circulation reducing process is executed, the center position of the picture can be simultaneously translated towards the center of the thumbnail, so that the center of the picture is overlapped with the center of the link icon when the reduced picture size gradually changes to the size of the link icon, and the effect of automatically flying the picture into the link icon is simulated; similarly, an automatic zoom-out process may also be applied to make the background picture disappear at the center of the desktop or other positions, and a more complex automatic gradual zoom-out effect may also be achieved by changing the center translation rule and adding more intermediate sizes. This display effect improves the user experience.

Preferably, the selection of the link icon is scrolling a scroll wheel of a computer pointing device over the link icon, and the displaying of the content of the document on the desktop background is a step-by-step enlarged display of the content of the document on the desktop background in an automatic manner until it reaches a certain preset size or display scale, such as: receiving an amplifying instruction of a user for pushing a roller wheel for the first time on a link icon B adjacent to a link icon A of a current desktop background file to obtain the file content pointed by the link icon B, firstly drawing the file content on an area, which just covers the link icon B, of the desktop, wherein the initial position size of the file content is the same as that of the link icon B, then repeatedly moving the drawing position and amplifying and redrawing until the center of a final drawing picture is coincided with the center of a desktop window, and the maximum edge size of the drawn picture is 1/3 of the size of the corresponding desktop window, and then setting the picture file on the desktop background in a larger proportion than the previous time as the scrolling and amplifying operation continues. The effect achieved in this way is: when the link icon is a thumbnail of a desktop background file, when a user sends a scroll amplification instruction on a certain link icon for the first time, the user can see that the thumbnail is gradually amplified and flies to the center of the screen, and actually, the background file corresponding to the thumbnail, not the thumbnail itself, is automatically amplified and translated to the desktop background center. Those skilled in the art will appreciate that the starting position, starting size, target position, and target size of the auto-scaling process may be varied as desired.

Preferably, the computer pointing device may be a mouse, a pointing stick, a trackball, or a touch pad, and is not limited to these devices. The computer pointing devices can send operation instructions to the computer device through the communication interface to realize the control operation of the computer device, wherein the mouse is most widely applied.

Preferably, the selection of the link icon is a single click of a computer pointing device key, a double click of a computer pointing device key, a scroll of a scroll wheel of a computer pointing device, or a depression of a specific key of a keyboard on the link icon. For example, there may be a single or double click command using a left or right button of a mouse, or the like.

Preferably, when the desktop background is set, besides the modes of tiling, stretching, centering and the like in the prior art scheme, and full display of the picture according to the width and full display according to the length, the invention provides an intelligent filling mode related to the difference coefficient of the aspect ratio of the picture and the desktop window, wherein the intelligent filling mode takes the set critical aspect ratio difference coefficient of the picture and the desktop background window as a boundary line and determines the adopted background picture scaling display mode according to the size relationship between the actual aspect ratio difference coefficient and the set critical aspect ratio difference coefficient. For example: when the actual height-width ratio difference coefficient of the picture file and the desktop window does not exceed the critical height-width ratio difference coefficient, displaying the picture on the desktop background in a stretching mode that the desktop window is filled with the picture in the longitudinal direction and the transverse direction; and when the actual height-width ratio difference coefficient of the picture file and the desktop window is larger than the critical height-width ratio difference coefficient, keeping the height-width ratio of the picture before and after scaling unchanged, and stretching and displaying the picture on the desktop in an equal ratio mode in which the desktop window is filled with the picture according to the relative long edge. The implementation effect of the method is that the desktop background can adopt different default display modes according to different aspect ratios of the pictures: when the aspect ratio of the picture is approximately the same as that of the desktop, the user can obtain the full-screen desktop display effect that the desktop window is filled with the picture with small deformation; for pictures with high aspect ratio of portrait and large difference of desktop background, selecting a longitudinal filling mode, reserving blank areas on the left side and the right side of the screen so as to keep the proportion of the pictures unchanged, and for wide pictures of landscape types, selecting a transverse filling mode, and reserving blank areas on the upper side and the lower side of the screen; when the actual height-width ratio difference coefficient of the picture file and the desktop window does not exceed the critical height-width ratio difference coefficient, the picture file can be enlarged and displayed on the desktop background in a short edge filling mode, and the implementation effect is as follows: a part of two ends of the long edge is abandoned, and an equal-ratio full-screen display effect is obtained, and meanwhile, the display effect is prevented from being influenced by blanks on two sides of the short edge. The method is realized by the following specific steps:

let the height and width of the picture be h_pic，w_picThe height and width of the table top are h_desk，w_deskThe critical aspect ratio difference coefficient a, which may be set by the user, indicates the degree of distortion of the picture that the user can tolerate. Calculating aspect ratio S_pic＝h_pic/w_pic，S_desk＝h_desk/w_deskThe actual aspect ratio difference coefficient m is abs (S)_desk-S_pic)/S_deskIf m & lta & gt, the size ratio of the picture is close to that of the desktop, the deformation degree of the picture displayed on the desktop in a stretching mode is within a tolerable range of a user, the picture is displayed on a desktop background in a stretching mode that a desktop window is filled with the picture in the longitudinal direction and the transverse direction, and the actual scaling factors of the picture in the transverse direction and the longitudinal direction are unequal and are unequal in stretching ratio. If m is larger than a, the difference between the size ratio of the picture and the size ratio of the desktop is larger, the deformation degree of the picture displayed on the desktop by stretching exceeds the tolerable range of a user, and at the moment, the aspect ratio of the picture before and after zooming is kept unchanged, and the picture is displayed according to the relative lengthAnd (3) displaying the mode equal ratio stretching of the edge filled with the desktop window: if h is_pic/w_pic，＞h_desk/w_deskCalculating the scaling of the picture as h according to the target that the picture is longitudinally filled with the desktop_desk/h_picThen, drawing of the picture on the desktop is completed at the scaling, and the mode is generally automatically applied to portrait mode photos taken vertically; if h is_pic/w_pic，＜＝h_desk/w_deskThen, the scaling of the picture is calculated as w according to the goal that the picture is horizontally filled with the desktop_desk/w_picThen, drawing of the picture on the desktop is completed at the scaling, and the mode is usually automatically applied to display of the picture in the wide landscape mode.

Another alternative fill method: when m is less than a, a full screen stretching mode is not adopted, but a short edge filling mode is adopted, the algorithm can be easily deduced by referring to the judging method when m is more than a in the previous example, and repeated description is not needed, at the moment, the short edge is filled in a desktop window, and parts at two ends of the long edge are invisible because the parts exceed the screen, so that the mode has the advantages that the equal-ratio full screen display effect can be achieved by abandoning one part at two ends of the long edge, and the ratio difference coefficient of the height-width ratio between the picture and the desktop is small, the proportion occupied by the abandoned parts is correspondingly small, and the integrity of the picture is; for the case of m > a, the long side fill mode of m > a described above can still be employed, but is not limited thereto.

As another extended embodiment of this embodiment, the link icon may not only point to various types of picture files, but also point to various multimedia files, such as animation files, audio files, video files, web pages, text files, and other multimedia files, and after the user selects the link icon, the corresponding file content may be displayed on the desktop background, and for the file that needs the media player to display its content, the corresponding media player program or control, and plug-in are automatically invoked to play the file. During playing, the movie is played on the desktop background, for example, by adding a sub-window of a desktop window on the desktop, the movie can be played on the desktop background by loading a media player control in the window or writing a decoding playing code by itself, and in this way, the desktop operation can be performed while the user enjoys the movie. As an extension, the user can also set to switch to a pop-up window for playing. Similarly, for flash animation, URL address, text file, etc., the content can be displayed directly on the desktop background in a similar way, except that corresponding presentation components may be used or corresponding code needs to be written for different file types. The support for the multimedia files enriches the selection range of users, increases the functions of desktops and is more convenient for the users to call the media files. It should be noted that, for other types of files except for pictures, the method for generating the link icon of the thumbnail type may also use an operating system or a component supporting the display of the type of file to intercept the display effect, or rewrite the code according to the file type structure to read the data of the file, obtain the thumbnail according to the file decoding algorithm, and store the thumbnail in the data structure of the link icon as an attribute value of the link icon.

In order to facilitate the downloading of pictures from the network, whether new picture files exist on the network can be checked at regular time or during starting according to the default or user-set URL addresses stored in the picture files on the network, if the new picture files exist, the new picture files are downloaded, the new picture files can be displayed on the topmost layer of a desktop in a semitransparent mode, and the pictures disappear after the display timing is finished or a user clicks a specific area. The newly downloaded pictures can also be displayed on the whole desktop or in a desktop floating window arranged on the desktop.

The invention can also use the operation instruction of the mouse pointer in the special area on the screen to complete different operations, preferably define the command in 9-grid mode, virtually define the blank area of the desktop after setting the desktop background into the 9-grid area, and appoint corresponding operations for the mouse operation information of each area, such as: and double-clicking in the grid at the right side to switch the next desktop background picture, double-clicking in the grid at the left side to switch the previous desktop background picture, double-clicking in the grid at the middle part to switch between full and previous snapshots, double-clicking in the grid at the upper part to switch the previous snapshot, and double-clicking in the grid at the lower part to switch the next snapshot. The advantage of this is that need not to provide the function of abundant desktop background quick adjustment with the help of extra control interface. As an extension, similar definitions of "4 squares", "6 squares", etc. may also be specified. The blank area is the largest rectangular area which can be determined on the desktop background and does not include the shortcut, and the space occupied by the side column window which is parked at one side of the desktop window can be deducted during calculation.

Referring to fig. 7, there is shown a flow chart of embodiment 2 of the method of the present invention.

In this embodiment, taking the windows xp operating system as an example, the link icon in this embodiment is displayed in the form of a thumbnail of a picture file, and the thumbnail is displayed in a blank area of a desktop, compared with embodiment 1, page turning and scrolling control, and desktop scaling and translation control are added, which specifically includes the following steps:

and step 701, dividing a blank area of the desktop.

For an operating system desktop actually used by a user, the number of shortcut icons placed on the desktop is generally small, and the shortcut icons are generally arranged on the left half part of the desktop, while the right half part of the desktop is basically a blank area, and the position information of the blank area can be obtained through an interface calling function provided by windows XP, for example, the position of the rightmost shortcut icon on the desktop can be obtained, and then the width of the right blank area can be calculated, and the height of the blank area can be calculated according to the position and the height of a task bar, so as to obtain the position of the blank area.

And setting the distance between the blank area of the screen and the thumbnail. Suppose the width of the available blank area on the right side of the acquired desktop is w_totalHeight of h_totalTo hold the screenThe appearance of the display effect is beautiful, and the longitudinal and transverse intervals w between the blank area on the right side of the desktop and the thumbnail drawing area need to be set_margin，h_marginMeanwhile, the longitudinal and transverse spacing w between the thumbnails needs to be set_delta，h_deltaThe thumbnail has a total drawing area width w_total-w_marginHeight of h_total-h_margin. It should be noted that, when the desktop implements application guidance in different technical solutions, it does not necessarily adopt the form of shortcut icons, but may also adopt layered, classified menus, drawer interfaces, etc., which are not in conflict with the method for acquiring blank areas described in the present method.

The blank area may be located at a different location depending on where the shortcut icon is located on the desktop, for example, when the shortcut icon is located on the right side of the desktop, the blank area may be in the left portion of the desktop, and in some other cases, the blank area may be in the middle or upper and lower portions of the desktop.

Step 702, setting a thumbnail in a blank area of the desktop.

And obtaining a path of the picture file according to the picture file which is preset by a user and is to be set as a desktop background, and extracting a thumbnail of the picture file as the attribute of the thumbnail.

As for the size of the thumbnail, the size setting of the thumbnail by pixel may be set by the user in advance.

When thumbnails are displayed, the number of thumbnails that can be displayed on each screen is limited due to the physical area of the screen display size, and if each page is displayed according to the number of thumbnails that can be accommodated, which is calculated according to the physical area size, page turning operation is required when there are many thumbnails. The number of thumbnails displayed per page may be set by the user, and when the number exceeds the number that can be displayed per screen limited by the physical space of the screen, a page turning operation may be performed instead by providing a scroll operation control.

In the display style of the thumbnail, the thumbnail outer frame display effect can be designated by the user, for example, a frame with a solid shadow, a raised effect, and the like are used.

Taking windows XP as an example, the method is expressed by taking shortcut icons arranged on the left side of a screen as an example, counting the total number of given picture files, and calculating the row and column number of thumbnails displayed on each page according to the following formula:

n_rows＝(h_total-h_margin)/(h_thumb+h_delta)

n_cols＝(w_total-w_margin)/(w_thumb+w_delta)

wherein n is_rowsNumber of lines, h, representing thumbnail_tota1Height, h, of the desktop blank area_marginRepresenting the size of the space reserved in the longitudinal direction of the thumbnail, h_thumbHeight, h, of the thumbnail_deltaIndicating the vertical spacing between thumbnails. n is_colsNumber of columns, w, representing thumbnails_totalWidth, w, of the desktop blank area_marginRepresenting the size of the space reserved in the lateral direction for the thumbnail, w_thumbWidth of the thumbnail, w_deltaIndicating the lateral spacing between thumbnails. And the total paging number of the pictures is set and calculated according to the total thumbnail number and the display number of each page, and the calculation formula is as follows:

n_pages＝n_pics/(n_rows*n_cols)+n_picsmod(n_rows*n_cols)

wherein n is_pagesNumber of divided pages, n, representing thumbnail_picsIndicates the number of pictures, n_rowsNumber of rows, n, representing thumbnails per page_colsNumber of columns per page thumbnail.

The method for setting the number of rows and columns in this embodiment is only an optional solution and is not listed for the purpose of limitation.

And then drawing a page of thumbnail in a blank area of the desktop, when the number is less than one page, drawing only the actual number of thumbnails, when the number is more than one page, only displaying 1 page, placing a page turning control mechanism at the edge so that a user can execute page turning control, wherein the page turning control mechanism can be a number with a link function displayed as 1-n, can be added with a number input box for inputting a page number to be displayed, a jump link of the next page, the last previous page and the last page, and can also be a conventional paging label (such as a tab control of windows) and other interface elements which can be used for paging control.

Referring to fig. 8a, which is an effect diagram of thumbnails displayed in a blank area of a desktop, a desktop background 801 is divided into 2 main areas, namely a shortcut area 804 and a thumbnail area 805, the shortcut area is used for displaying an original shortcut 803, a thumbnail 802 is displayed in the thumbnail area 805, the effect diagram further comprises a page turning control button 806 and a scroll bar 807 for performing scroll control in one page, and the appearance and visibility of the page turning control button 806 and the scroll bar 807 can be set according to the habit of a user.

In windows xp, a method for controlling the scrolling of the screen display by a mouse is adopted: when a user presses a middle mouse button, a scroll indication icon is displayed at the position of a mouse pointer, and at the moment, when the user moves the mouse up, down, left and right on the icon, the user is understood to automatically execute scroll operation, and the farther the distance from the icon is, the faster the scroll speed is. This function will continue to operate continuously until the user operates the middle key again or until the mouse pointer is brought back to the vicinity of the scroll indicator icon, which makes the control of the amount of scrolling quite difficult and is rarely accepted by the user in practice. Compared with the method in the prior art that the distance between the current position of the mouse and the position of the roller when the roller is pressed is related to determine the rolling speed, the method disclosed by the invention has the characteristics of strong controllability and intuitive effect.

In this embodiment, holding down the mouse wheel in the thumbnail mode to move the mouse is designed to move the thumbnail list smoothly, and scrolling the mouse wheel is defined as a list scrolling operation, and the specific method of list scrolling is as follows: while the mouse wheel is scrolling, the step amount of scrolling is calculated according to the Y coordinate of the mouse pointer on the desktop (similarly, the technology can also be applied to other windows) and the total height of the desktop window, and the visible thumbnail is adjusted according to the step amount and the drawing refreshing is completed. When the mouse is set to be close to the top end, the mouse is set to be updated in a whole page when a user performs a scroll operation, and is set to be in a step scrolling unit by taking one line when the lowest area of a desktop window performs a similar operation, and the operation response step number of the mouse at other positions in the longitudinal direction is interpolated and converted in proportion, wherein the calculation formula is as follows: assuming that the top Y coordinate of the desktop window is 0, the bottom Y coordinate is Y, the mouse pointer scrolls at the bottom by a step amount t1 (which is 1 or designated by the user), and the mouse pointer scrolls at the top by a step amount t2 (which may be the number of lines that can be contained in the entire page or designated by the user), when the Y coordinate of the mouse pointer on the screen is x, the corresponding step amount should be (t2-t1)/Y (Y-x).

Step 703, receiving the selection of the thumbnail from the user, and setting the content of the file pointed by the selected thumbnail as the desktop background.

And when the user sees the thumbnail of the picture to be selected in the thumbnail list on the desktop, clicking the thumbnail and setting the picture file pointed by the thumbnail as the desktop background.

When the thumbnail selected by the user is obtained, the information of the mouse can be intercepted, the index number of the thumbnail selected by the user can be obtained through calculation, the index number is the number of each thumbnail, the corresponding thumbnail is found according to the index number, the pointing attribute of the thumbnail is taken out, the directory path and the file name information of the picture file are stored in the pointing attribute, then the data of the picture file is read and written into a desktop background data buffer area, the picture is processed in an intelligent filling mode, and the function of setting the desktop background is realized.

In addition, when a user places a mouse on a thumbnail to be selected and rolls a mouse wheel forwards, the system intercepts the cursor position and the wheel operation of the mouse, judges that the rolling operation is performed on the thumbnail, calls a corresponding processing program, obtains the index number of the thumbnail positioned under the cursor by the processing program, further obtains a picture file pointed by the thumbnail, and gradually enlarges and displays the picture file on a desktop background in an automatic mode until the picture file reaches a certain preset size or display scale, such as: receiving an amplifying instruction of a user for pushing a roller wheel for the first time on a link icon B adjacent to a link icon A of a current desktop background file to obtain the file content pointed by the link icon B, firstly drawing the file content on an area, which just covers the link icon B, of the desktop, wherein the initial position size of the file content is the same as that of the link icon B, then repeatedly moving the drawing position and amplifying and redrawing until the center of a final drawing picture is coincided with the center of a desktop window, and the maximum edge size of the drawn picture is 1/3 of the size of the corresponding desktop window, and then setting the picture file on the desktop background in a larger proportion than the previous time as the scrolling and amplifying operation continues. The effect achieved in this way is: when the link icon is a thumbnail of a desktop background file, when a user sends a scroll amplification instruction on a certain link icon for the first time, the user can see that the thumbnail is gradually amplified and flies to the center of the screen, and actually, the background file corresponding to the thumbnail, not the thumbnail itself, is automatically amplified and translated to the desktop background center. The process of switching the background picture from the thumbnail state to the full-screen background and the user interaction process are organically combined in the response mode, so that the controllability of the setting process is enhanced, and the aesthetic enjoyment can be brought to people through the process of gradually amplifying. Rolling the scroll wheel forward here represents zooming in, but an alternative convention.

In the above-mentioned background picture rendering, the scale and display area of the picture may be controlled when filling the buffer to the desktop instead of being adjusted when writing the picture into the buffer, or the data of the picture file may not be written into the buffer but may be directly written into the desktop background, which has the advantage of reducing the processing steps, but the speed may be relatively slow and inefficient when performing the step 705 described below.

Step 704, receiving a desktop background scaling instruction of the user, and scaling up or down the desktop background picture.

After the desktop picture is set, when the complete picture is displayed in a mode of filling the desktop, due to the limitation of the visible area of the desktop, the details of the picture are not clear, if the resolution ratio of the used background picture is higher, a user can select a local part of the picture, and the desktop system automatically amplifies the local part of the picture and fills the desktop background, so that the display style of the desktop background can be better adjusted, more selections for adjusting the display effect are provided for the user, and the use is more humanized.

When a user presses a left mouse button on a desktop background picture to move and select a local part of the desktop background picture, the system obtains the current position and action of the mouse, after the operation of judging that the local part of the background picture is selected, the coordinates of the upper left corner and the lower right corner when the mouse of the user is selected are obtained through calculation to obtain a selected range, the data of the selected local picture can be obtained according to the range and the display proportion and range of the current desktop, the local picture data are written into a desktop background buffer area, the displayed proportion is adjusted by taking full-screen display of the local picture data as a target, and then the local picture data are replaced into the background of the current desktop, so that the local amplification operation of the specified area of the desktop background is realized. And if the shortcut icon exists in the area selected by the user, the background picture is not processed, and the message is transmitted to the original processing program to process the selected shortcut icon.

In the above process, the obtained selection range may also be adjusted to make the aspect ratio of the selection range consistent with the aspect ratio of the desktop, the adjusted selection range may obtain data of the local picture, and subsequent processing may be performed to make the display of the picture not deformed after the local picture is enlarged to the entire desktop background.

In this step, the specific operation of enlarging and reducing the background picture is that the user rolls the roller of the mouse on the desktop background picture, the system intercepts the position of the mouse cursor and the operation of the roller, calls a corresponding program, enlarges or reduces the picture in the desktop background in proportion, and then redraws the background picture.

When the desktop background is reduced, a threshold value with the minimum size is preset, when the reduced desktop background picture reaches the threshold value, the step of reducing and displaying the desktop background picture on the desktop is automatically circulated for a plurality of times, the picture is automatically reduced until the picture reaches the preset size, for example, the preset size can be set to be equal to the size of a link icon, under the condition, when the automatic circulation reducing process is executed, the center position of the picture can be simultaneously translated towards the center of a thumbnail, so that the center of the picture is overlapped with the center of the link icon when the reduced picture size gradually changes to the size of the link icon, and the effect of automatically flying the picture into the link icon is simulated; similarly, an automatic zoom-out process may also be applied to make the background picture disappear at the center of the desktop or other positions, and a more complex automatic gradual zoom-out effect may also be achieved by changing the center translation rule and adding more intermediate sizes.

The invention also provides a method for translating the desktop background picture, which comprises the following steps: when the desktop background picture is displayed on the desktop window in a size larger than the thumbnail, the user presses a specific keyboard combination or mouse key combination to adjust the display position and area of the desktop background picture. For a desktop background displayed in a mode smaller than a full screen, the method has the display effect that the whole position of the picture on the desktop is moved, for the desktop background which is full of or exceeds the size of the full screen of the desktop, the desktop can only display a part of the picture, and the method can be used for operating and displaying the effect that the specified part of the picture displayed in the range of a desktop window can be flexibly adjusted on the desktop.

For pictures with higher resolution, the invention can directly provide free scaling and translation operations similar to a picture browser on the desktop without starting external picture browsing software, and can fully meet the appreciation requirements of users on picture details or some main objects on the desktop.

The invention can also realize the related operation of the file in the thumbnail area directly, such as: the method comprises the steps of obtaining a selected thumbnail list through judging a keyboard and a mouse selection area, obtaining a corresponding list of picture files according to the thumbnail list, copying the picture files to a clipboard of a system, and then using a related file operation API (application program interface), namely the picture files, to execute operations such as selection, cutting, copying, pasting, moving and the like similar to ordinary files. When the operation of the picture file is realized, the OpenClipboard function of the API of the system can be called to open the clipboard, and the SetClipboardData function is used to set the file to be copied.

Several details of this embodiment are further described below.

In this embodiment, a specific implementation method for determining a corresponding thumbnail according to a position of a mouse is shown in fig. 9, and specifically includes: presetting an index number global variable for recording the index number of a current thumbnail, when a cursor of a mouse moves on a desktop, obtaining the coordinate position of the mouse on the current desktop by intercepting the message transmission of a windows XP, wherein the coordinate value is usually one, initializing the index number global variable in order to judge on which thumbnail the mouse is positioned, then calling by using a desktop object method provided by the windows XP to obtain all thumbnails, circularly taking each thumbnail, firstly taking the first thumbnail for the first time, calculating the position of the thumbnail, judging whether the mouse is positioned on the thumbnail according to the position of the mouse obtained in the previous time, taking down one thumbnail if the mouse is not positioned on the thumbnail, then calculating and judging until all thumbnails are circularly completed, if the mouse is positioned on one thumbnail, considering that the thumbnail is selected by a user as the current thumbnail, and setting the value of the index number global variable as the index number of the thumbnail, and if the mouse is not positioned on any thumbnail, the user is considered not to select the thumbnail, no processing is carried out, the message is transmitted back to the windows XP system, and other responses and processing are carried out by the windows XP system. According to a windows XP conventional operation method, a plurality of thumbnails can be selected by combining shift, ctrl and other key combinations and mouse frame selection, and functions such as pasting and copying can be used, for example, in a resource manager, a plurality of picture files are selected, a copying function is selected, a mouse is moved to a desktop, the pasting function is selected, a system intercepts the message, the following processing is carried out, the selected picture files are copied to a pre-specified desktop background picture file default directory, thumbnails are generated and placed on the desktop, and a user can click the thumbnails to carry out desktop background setting; or the picture file is not copied into the default directory of the desktop background picture file, and a thumbnail pointing to the selected picture file is directly set on the desktop for the user to click.

The thumbnail corresponding to the current position of the mouse can be obtained by the method of fig. 9, which provides a premise for further performing other operations on the thumbnail.

In this embodiment, a specific implementation method for setting a desktop background according to a mouse click is shown in fig. 10, and specifically includes: when a user clicks a thumbnail on a certain thumbnail on a desktop, firstly intercepting the clicking operation message of the mouse, taking the position of the current mouse, obtaining which thumbnail the mouse is positioned on according to the method in the above-mentioned FIG. 9, obtaining the thumbnail selected by the user, judging whether the thumbnail object is empty, knowing whether the picture file pointed by the thumbnail exists by judging, avoiding the problem that the picture file cannot be taken, finishing the program if the thumbnail object is empty, if the thumbnail object is valid, obtaining the path and the file name of the pointed picture file from the attribute of the thumbnail object, judging whether the obtained picture is the picture which is already set on the background of the current desktop, if so, finishing the program, if not, writing the data of the read picture file into a preset picture buffer area bmp1, refreshing the display of the desktop window, and entering the drawing process of the desktop window by self-defining, as described in steps 1005 to 1010: creating a desktop-compatible device context hdcMem by using a createcomapatibledc (create memory device context) function provided by a system, creating a memory image cache bmpMem through createcomapatiblebitmap (create device-compatible memory bitmap), loading bmpMem into hdcMem through SelectObject (select object to device context), copying picture data in a picture cache region bmp1 into hdcMem through a BitBlt (bitmap copy) function, calling an original processing procedure WM _ PAINT (drawing message) message of a desktop window through callwindowpwroc (call window processing procedure), using hdcMem as a parameter, drawing original contents of the desktop (including shortcut icons and the like), and copying the drawn contents in hdcMem into a DC (device context) of the desktop window through a BitBlt (bitmap copy) function, thereby completing the setting and displaying of the desktop background. It should be noted that step 1005 to step 1010 are also a custom drawing process of the desktop window, and the system automatically invokes step 1005 to step 1010 each time the desktop window needs to be refreshed.

In the above method, the link icon may also be displayed as a symbolic mark or a textual mark, and a combination thereof.

By the method, the process of receiving the thumbnail selected by the user and setting the picture file pointed by the thumbnail as the desktop background is realized, and the method of drawing the background picture in the buffer area and copying the image data in the buffer area to the desktop background is adopted, so that the speed of other related operations of the desktop background can be increased. In this embodiment, a method of directly copying the data of the picture file onto the desktop background may also be adopted. In this embodiment, other operations related to the background picture, such as scaling, translation, etc., may also share the same buffer area, so as to achieve the purpose of increasing the operation speed with the least memory occupation.

Thumbnails to be operated are displayed in a web page added to a desktop, and a single thumbnail can be displayed using a built-in object in HTML (hypertext markup language). Preferably, the thumbnail can also be placed in a window on the web page, where the window can be realized by HTML object simulation. The source of the desktop background setting items such as pictures, videos and the like and the thumbnails can be downloaded from a server and displayed on a webpage, or a COM (component object model) component is embedded in the webpage, and local files are accessed through the COM component and displayed on the webpage.

Through an event response function provided by the DHTML (dynamic hypertext markup language), the operation event is responded by using a script (such as JavaScript) in the webpage, and the operations such as selection and zooming of the thumbnail are controlled. The thumbnail object can store attributes such as the position and display mode of the thumbnail original file. In this embodiment, the specific implementation method for setting the desktop background according to the mouse click is as follows:

firstly, a mouse event response function is added to a thumbnail object in a webpage, and a user clicks a thumbnail to trigger the execution of the function. And obtaining a thumbnail object of the trigger event from the event parameter, and obtaining the original file position of the thumbnail from the attribute of the object. An HTML object displaying a thumbnail original file is created or an existing hidden HTML object is displayed, the HTML object is filled in the entire web page, and z-index (stacking order) of the HTML object is set to be positioned at the top of all page objects. And setting the data source of the HTML object as the original file position of the thumbnail to complete the setting of the desktop background.

As can be understood by those skilled in the art, most functions of a common desktop application can be simulated and realized on a page by using DHTML, and functions which are not easy or can not be realized in part in the webpage, such as obtaining blank area information of a desktop background, and the like, can be expanded and realized by using a COM component. For implementing other features of the present invention by using web pages, the core idea is the same as that of embodiment 1, and those skilled in the art can easily implement the core idea with reference to embodiment 1.

In another scheme for implementing the invention by using the ActiveDesktop technology, a COM component is embedded in a webpage, and the COM component is filled in the whole webpage and integrated on a desktop for display. The embedded COM component completes the display and control of the thumbnail and desktop background in response to the operation message, and the implementation of the present invention is completed in the COM component as described in embodiment 1.

In order to make the layout of the thumbnails on the webpage and the background of the desktop more consistent, the access of the desktop attributes can be added into the webpage components, and corresponding operations are executed, for example, the thumbnails and shortcuts and other sidebar programs can be prevented from colliding in the interface layout by acquiring the blank area of the desktop and displaying the thumbnails in the blank area.

In the scheme of implementing the present invention by using the ActiveDesktop technology described above, the content on the Web page may also be flash (interactive vector graphics and Web animation) animation or other objects that can implement user interaction. In an embodiment, the web page can be automatically designated as the desktop background, and a function menu or button for calling ActiveDesktop to designate the web page as the desktop background is provided on the web page, and when the menu or button is selected by the user, the web page is designated as the desktop. Several different web pages may also be provided for selection by the user. The provided web pages may be stored on a local computer device or on a remote server, and may be accessed by a user via a network protocol (e.g., ftp or http).

In yet another embodiment of the present invention, a separate desktop program is created to simulate the desktop functions of the operating system, instead of the desktop program of the operating system, which is capable of intercepting the messages and commands of the operating system to display the desktop to simulate all the functions of the desktop of the operating system, and the implementation of the present invention is completed in the desktop program as described in example 1.

In yet another embodiment of the present invention, a separate desktop program is created and the parent or owner window of the program's main window is set as the desktop window, such that the program's main window is located below the desktop shortcut, above the desktop background, and integrated on the desktop. The implementation of the present invention is completed in the desktop program as described in embodiment 1.

When the method is used for an operating system supporting a 3D desktop, the core ideas are similar, but the specific functions called when the desktop is operated are different, and the appearance effect of the method can be adaptively adjusted according to the 3D characteristics, so that the display style is uniform.

The invention can also be used for mobile equipment or digital television set-top box and other equipment, because there is no mouse equipment, the operation is mainly operated by a keyboard or a remote controller, and the operations of thumbnail drawing, background setting, background zooming and translation and the like are similar to the previous embodiment. It will be readily appreciated by those skilled in the art that the specific code may be varied and the core concepts may be substantially the same when the present inventive arrangements are implemented on different operating systems or computer devices.

The method, the device and the system for controlling the desktop background provided by the invention are introduced in detail, and the principle and the implementation mode of the invention are explained by applying specific examples, and the description of the embodiments is only used for helping to understand the method and the core idea of the invention; meanwhile, for a person skilled in the art, according to the idea of the present invention, there may be variations in the specific embodiments and the application scope, and in summary, the content of the present specification should not be construed as a limitation to the present invention.
