Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a multi-window control method, and in particular,
The present invention relates to a window control method suitable for operating a large number of windows.

[Conventional technology]

Conventionally, regarding the woodcutter's window control method, as described in Japanese Patent Application Laid-Open No. 118833, a method to easily redisplay the target window at the top when it is hidden by another window has been discussed. It was getting worse.

[Problem a that the invention attempts to solve]

The above-mentioned prior art relates to a means for selecting a window that has already been made invisible, and does not take into account the problem of preventing all windows from being hidden. Therefore, in order to redisplay an invisible window, there is a problem in that an operation different from normal operation is required or the display area of the window is narrowed.

The purpose of the present invention is to prevent windows from overlapping more than necessary by widening the area where windows are arranged, and also to reduce the complexity of operations caused by expanding the area, and to provide flexibility in the operation method. The purpose is to have

[Crafts to solve problems]

In order to achieve the above object, the present invention makes the background on which the window is arranged larger than the display screen.

Further, in order to be able to display any position within the background, the entire screen is regarded as one window, and a scrolling means is provided so that the display contents can be freely scrolled.

Furthermore, in order to prevent windows that you want to always display on the screen from moving off the display screen due to screen window scrolling, you can fix the window to an arbitrary area on the display screen and scroll the screen window. A means is provided to prevent the display position from being dominated by the user.

[Effect]

This is because there is no limit to the size of the background screen.

All windows must fit within a narrow display screen.

This eliminates the need for overlapping windows, making it possible to avoid overlapping windows as much as possible, and switching the active window (currently selected window) without complicated operations. Furthermore, the arrangement of windows can also be made flexible.

The screen/window can be scrolled using scrolling means such as an elevator-type scroll bar or scroll button, or a two-dimensional scroll screen that reduces the entire background screen onto the display screen and then moves the display screen frame. Therefore, any position can be displayed.

Furthermore, by fixing a window to a specific position on the screen regardless of whether it is open or iconized, you can view data in multiple windows in different locations while viewing data in one window. It's easy to use, as you can edit files, keep icons, etc. in small windows where you can always see them, and take them out when you need them.

〔Example〕

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing the overall configuration of an embodiment of the present invention.

In the figure, a window management table 2000 is a table that manages the positions, sizes, etc. of a plurality of open windows. The coordinate conversion means 3000 converts the position and size of the window managed by the world coordinates, which are the coordinates of the evening scene, into the graphic RAM 5000.
This is a means of converting to screen coordinates for display. Moreover, coordinate transformation is not performed on the position and size of the window managed by screen coordinates due to the fixed plane position.

Here, the control unit 1000, the coordinate conversion means 3000 activated by the control@1000, and the screen scrolling means 4000 are placed on the ROM or RAM,
Further, it is assumed that the window management table 2000 is placed on RAM.

FIG. 2 shows a diagram showing the relationship between a screen window and the background on which the window is placed. The figure (Ji) is a screen window, and the figure (b) is a diagram showing the entire background. The dashed rectangle 110 in this figure represents that its interior is displayed within the screen window 100.

In FIG. 212(b), there are four windows wd1. wd2. wd3. wd4 is open, and a rectangle 110 containing wdl and wd2 is displayed within the screen window 100. If the screen window 100 is scrolled here, the position of the dashed rectangle 110 will move and the displayed content of the screen window 100 will change.

Here, in FIG. 2(a), screen window 1
00 scroll bar and 4
00 is displayed, but this may be a two-dimensional image such as that shown in FIG. Alternatively, it is also desirable to use the above two scroll means in combination.

FIG. 3 is a diagram showing an example of how the window management table 2000 is constructed. The window management table 2000 consists of a header section 2100 and a main body section 2200.

Screen windows are also like other windows.
It is managed within the main body section 2200.

The main body section 2200 is composed of the items shown below.

(1) title...window name (2) ap
... Type of application software running on the window (3) fp ... Pointer to the window with one display priority (4) bp ... Pointer to the window with one display priority lower ( 5) ff...Flag indicating whether to fix the position on display ii1 screen (6) Xm1n, 7m1n, Xmax, Yma
x: The x and y coordinates (3) and (4) of the two diagonal points of the window are bidirectional pointers for linking windows based on display priority.

In the header section 2100 of the window management table 2000, (7) FP: Pointer to the window with the lowest display priority (F3) BP: Pointer to the window with the highest display priority It is possible to access windows in both directions using the windows indicated by these as a base point. Note that pointers fp and bp.

FP and BP do not indicate window numbers, but point to the number boxes for quick access of the window management table intangible part 2200.

In addition, (5) is a flag indicating whether to move the position of the window on the display screen accordingly when the display contents of the screen are scrolled, or to fix it so that it does not move. When it is, it is 1, otherwise it is 0.

The window coordinates in (6) are the coordinates on the background screen 200 shown in FIG. 2(b) when the flag in (5) is 0, and the coordinates on the background screen 200 shown in FIG. 2(b) when the flag in (5) is 1. ) on the screen window 100. However, the screen window coordinate values are always background screen 2.
00.

Note that the information regarding the screen window in the window management table body section 2200 is ignored except for the coordinate value (6).

FIG. 4 shows an example in which the screen window 100 shown in FIG. 2(a) is scrolled downward. Figure 4 (aJ
is an example of scrolling when the value of the screen fixing flag ff of window wdl in Fig. 3 is 0, and Fig. K4 (
b) is an example of scrolling when the value of the screen fixing flag ff is l.

#! 4(a), as the screen window is scrolled downward, the window wcll.

wd2. wd4 is also moving within the display screen. On the other hand, in FIG. 4B, window wd2. Although wd4 moves, the position within the display plane of wdl does not change.

Here, the screen fixation box 500 is placed, for example, in a title bar that displays a title, etc., and represents the current value of the screen fixation flag ff for that window. Also, for example, by clicking the screen fixing box 500 with a pointing device such as a mouse, the value of the screen fixing flag ff can be set to 0.
．． You can switch between 1 and 2. For example, suppose that the screen fixation box 500 is clicked with the mouse when the value of the screen fixation flag ff of the window wd1 is 0.

At this time, in the information regarding the window wdl in the window management table main body 2200, the value of the screen fixing flag ff is switched to 1, and the coordinates Xm1n
, ymin, Xmax, Yrnax are converted to screen coordinates. Coordinate transformation is performed using the formula shown below.

Xxmin' = Xtmin
(1))'tmin' = )'tmin -)'a
min (2)Xsmax'=XtmaxX
omax (3) Ytmax'= Ytmax
Yornax (41 Also, when the value of the screen fixing flag ff is 1, the screen fixing box 50
When 0 is clicked with the mouse, the value of the screen fixing flag ff is switched to O in the information regarding the window wdl in the window management table main body 2200.
The values of the coordinates Xm1n, Ymin, ax, )'max are converted to world coordinates, which are coordinates on the background. Coordinate transformation is performed using the formula shown below.

X5m1n”””tmin” Xem1n
(5) Fsmin""3'xmxn + F@min
(6) “””= “*max” “@w
ax (7)Xsmax'= 7nmax +
7nmax (8' Now, when it is necessary to redisplay the screen window due to moving or changing the size of the window, switching the active window, scrolling the screen window, etc.), the control unit 1
000 starts the coordinate transformation means 3000.

The coordinate conversion means 3000 converts the window management table 20
When the coordinate information of each window managed in 00 is world coordinate, it is converted to screen coordinate and set as display information in the window display table. The window display table is a table that stores display attribute information in descending order of display priority.

A processing flowchart of the coordinate conversion means 3000 is shown in FIG.

First, in step 301O, it is determined whether processing has been completed for all windows.

However, this does not include screen windows. Process completion determination is made using the window management table 2000.
This is done based on a bidirectional pointer FP, BPj'psbp, for linking windows within the same window according to their display priorities. That is, the process starts from the window pointed to by the FP with the lowest display priority, and after the window pointed to by the BP with the highest display priority is processed, the process ends.

In step 3020, pointers FP, BP, fp
, obtain the coordinate values of the window pointed to by the window number, which is the value of bp.

Next, in step 3030, it is determined whether the position of the window currently being processed is fixed within the screen window. If fixed, the coordinates obtained in step 3020 are screen coordinates, so there is no need to perform coordinate transformation, and the process jumps to step 3050. If it is not fixed, proceed to step 3040.

In step 3040, the window position expressed in world coordinates is converted to screen coordinates. Equations (1) to (4) are used for coordinate transformation.

From the screen coordinates of the processing window thus obtained, it is determined in step 3050 whether this window is even partially within the screen window. That is, it is determined whether the rectangle indicated by the coordinates X[n l n *Ymin*ring aX* YlnaX overlaps with the rectangle of the screen window.

As a result, if they do not overlap, there is no need to display them and the process returns to step 3010. If they overlap, step 306
Go to 0.

When it is determined in step 3050 that the window being processed is in the first display area, in step 3060 the window number and screen coordinates are set in the window display table, and then in step 301O
Return to

With the above processing, it is necessary to display the window! information can be created.

Incidentally, window display is performed by referring to the window management table and window display table, but at that time, if even one of the coordinate values set in the window display table is outside the display area of the screen window, the display area will be clipped.

〔Effect of the invention〕

Since the present invention is configured as described above, it produces the effects described below.

(1) By expanding the background screen on which windows are placed, flexibility in window arrangement can be increased, and windows do not need to be overlapped unnecessarily.

(2) By providing a scrolling means in the screen window, any position within the background screen can be easily displayed, and operations such as switching the active window can be easily performed.

(3) It is possible to fix the position of the window within the display area and prevent the window from being scrolled out of the display area by scrolling the screen/window. It has excellent operability because you can edit window data and keep track of the position of the regular ζ window.
