Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a window selection device, and more particularly to a window selection device that selects and outputs display data of a desired window under a multi-window system.

〔overview〕

The present invention displays the window markers (icons) of all windows, including windows that are not displayed on the screen, on a screen such as a CRT display, and only requires the operation of selecting and inputting a desired window marker from a signal input device. To make a hard copy of the display data of a desired window without any effect on the currently displayed window by making it possible to output the display data of the window corresponding to the in-toe indicator selected in . This also significantly improves the operability at that time.

[Conventional technology]

Under a multi-window system, multiple windows cannot be displayed on a CRT display, and these multiple windows are managed using a window management table. That is, the window management table stores the attributes of each window, such as its appearance and size, as well as the list structure between the windows.

With control based on such a window management table, some of the multiple windows are actually displayed on the CRT display, but other windows are hidden behind the displayed window, and still other windows are hidden. It is paused and not displayed on the screen.

Conventionally, window selection devices that select a desired window from among a plurality of windows and output the display data to a printer, for example, have been designed to be able to select only the windows that are actually displayed on the CRT display screen. It had become. Therefore, in order to output the data of the currently dormant window or the data of the window that is hidden behind the displayed window and is not currently visible, the dormant window must be redisplayed on the screen or covered. This required operations to display hidden windows on the CRT display by moving or reducing the size of the hidden windows.

[Problem that the invention seeks to solve]

However, in order to make a hard copy in a conventional window selection device, operations such as redisplaying a dormant window or adding transformations to a currently displayed window only add effort and burden to the operator. Moreover, it requires a great deal of effort to restore the original display to its original state, and furthermore, it has a negative impact on the reliability of data processing on a CRT display.

The present invention makes it possible to select a desired window, including windows that are not currently displayed, without adding any modification operations to the window currently displayed on a screen such as a CRT display (with an extremely simple operation). The object of the present invention is to provide a window selection device that can select a window and output the data.

In the figure, 11 is a mouse, and 12 is a keyboard. The mouse 11 and the keyboard 12 constitute the signal input device 1 of FIG. An operation signal for controlling the screen of the CR/T display 13, a window generation signal, a hard copy signal to the window blink 14, etc. are input from an input device such as a mouse 11 or a keyboard 12. The processor 15 is controlled according to a program stored in a ROM (not shown). processor 15
accepts input signals from the mouse 11 via the mouse control device 16, and receives input signals from the keyboard 12 via the keyboard control device 17. Of the signals input from the mouse 11 or the keyboard 12, the processor 15 stores information regarding each window in the window management table 18, and stores display data in the window memory 19. This window memory 19
In addition to window display data, a window indicator for selecting a window as described later, such as icon data, is stored. In order to display overlapping windows on the CRT display 13, the window management table 18 stores information about window positions, sizes, attributes such as pause flags, and relationships between windows, and uses a list structure to display the overlap status between windows. need to be managed.

FIG. 3 shows information stored in the window management table 18. Window management table daily information includes window width bpw, window height bph, screen X coordinate bpx, screen Y coordinate bpy, character size csize, line pinch pitch, next window pointer "p1 of previous window" pointer bp, i%

Here, click one of these icons with the mouse 11
Alternatively, when selected on the keyboard 12, control passes from the processor 15 to the hardcopy controller 22. The hard copy control device 22 retrieves the selected window data from the window memory 19, performs vertical and horizontal image conversion (not shown), and transfers control to the printer control device 23.

The printer control device 23 sends the vertically and horizontally converted window data to the printer 14, and the printer 14 prints the window data.

In addition, in FIG. 2, the window management table 18, window memory 19. The overlap control device 20 and the bit mover 21 constitute the hardware of the window display means 2, the hard copy control device 22 constitutes the hardware of the window data selection means 3, and the printer control device 23 and the blink 14 constitute the output means. 4.

2) Operation The operation of the window selection device configured as above will be explained. Note that the explanation of the operation of inputting a predetermined signal from the mouse 11 or keyboard 12 and displaying a window on the CRT display 13 is omitted since it has been described above.
In the following, a window that overlaps the CRT display 13 as shown in FIG. 5(a)
WinB is displayed on the screen and the window -in
If window WinD is hidden behind A and there is a dormant window WinC, all windows WinA, WinB, WinCXWin
The icons of D are shown in FIG. 5(b) with symbols 30, 31, 32, .
The operation for displaying on the CRT display 13 as shown at 33 will be explained.

Window WinA on CRT display 13.

When WinB is displayed, window WinD is hidden behind window WinA, and window WinC is in a dormant state, when a hard copy signal (not shown) is input from the mouse 11 or keyboard 12, the processor 15 reads the ROM. (not shown) starts an icon display program stored in the computer. FIG. 6 shows a flowchart of the icon display program. By running this program, all windows WinA, WinB, Wi
nC,、WinD icon CR、T display 1
3 can be displayed.

In the flowchart of FIG. 6, in step ST1, in order to search for the pointer to the icon data of the first window, first, the frontmost A pointed to by the pointer swap in the Hayes window management table (example shown in FIG. 4 (bl) Then, the start address of the window management table for window WinA) is stored in register P.

Next, based on the start address position of the window management table pointed to by register P, pointer 1comp to the icon data of this window management table.
1 is stored in a predetermined position of register r (step 5T
2). In this case, a pointer 1comp 1 to the icon data of the window WinA is stored at the first address of register r.

Next, in order to judge whether this window is the last window (this judgment is made as shown in Figure 4 (bl), the end mark NI [, (This is done by noting that L is stored.) Check whether the pointer fp is the end mark old LL in the window management table stored in the register P (step 5T3).
. In this case, the first window WinA is not the last window, but its management table pointer fpl
Since the old end mark LL is not stored in , the process advances to step ST4 to search for a pointer to the icon data of the next window WinB. In step ST4, the pointer fpL in the window management table currently pointed to by register P is tapped, and the start address of the window management table of the next window is stored in register P. As a result, the start address of the window management table of the second window WinB is stored in register P. Next, the process returns to step ST2 again, and the window Win
Pointer 1co to icon data of B's management table
Store np 2 at the next address location in register r.

As a result, the next address position of register r is a pointer to the icon data of window WinB.
np 2 is stored.

By repeating the above procedure, pointers to the icon data of windows WinC and WinD are added to the predetermined address positions of register r.1conρ3. 1conρ4 are stored sequentially. After the pointer 1comp4 to the icon data of the window WinD is deposited in the register r, it is determined in step ST3 whether the pointer rp4 of the management table of the window WinD is the end mark [[-[,]. Window WinD is the last window and the end mark NILL is stored in pointer fp4, so pointer 1compL to register r
, 1comp2 , 1comp3 , 1co
The storage of np4 is completed, and the process proceeds to step ST5 to display the icon on the CRT display 13. In step ST5, pointers 1conpl, 1con to the icon data sequentially stored in register r
ρ2゜1comp3, 1conp4 to respective windows WinA, inB, WinC,
The icon data storage location of WinD is searched, and the icon data of each window is extracted from this icon data storage location, stored in the window memory 19, and then transferred to the CRT display 13 under the control of the focus mover 21.
The icons are displayed as shown at 30, 31, 32, and 33 in FIG. 5(b), and the icon display process is completed. In this process, it is assumed that a certain link relationship is formed between the icon data stored in the window memory 19 and the display data of the window corresponding to this icon data.

After the icons are displayed on the CRT display 13 in this way, the operator selects the icon for the window for which he wants to make a hard copy using the mouse 11 or the keyboard 12, and the processor 15 transfers control to the hard copy control device 22 to make the hard copy. The copy selection device 22 is
The display data of the window corresponding to the selected icon is searched in the window memory 19 and taken out. Then,
The extracted window display data is converted into vertical and horizontal images and passed to the printer control device 23, and the printer control device 23 outputs the result to the printer 14.

In the embodiments described above, icons are displayed as window indicators for each window on the CRT display 13, and desired window data is printed on the blink 14 by selecting one of the icons using the mouse 11 or keyboard 12. However, as a modified example, instead of displaying the icon of each window on the CRT display 13, the title bar of each window is displayed, and the operator can select the desired title bar using the mouse 11 or keyboard 12. It is also possible to have the printer 14 print the window data. By displaying the title bar on the CRT display 13, a desired window to be hard-copied can be selected without making a mistake even when there are many windows.

Furthermore, in the above embodiments, a hard copy signal is input from the mouse 11 or keyboard 12 when displaying icon data or title bar data on the screen, but the window is displayed on the screen without inputting a hard copy signal etc. After the icon data or title bar data is displayed on the screen, the icon data or title bar data may be automatically displayed on the screen without the operator's intervention.

〔Effect of the invention〕

When selecting a window to make a hard copy to a printer, etc., you can simply perform a simple key operation from the signal input device without having to move or reduce the currently displayed window. In addition to the displayed window, you can arbitrarily select any of the currently displayed dormant windows or windows hidden behind other windows to output the display data. It is possible to obtain the effect that operability can be significantly improved without any loss in processing reliability.
