Description of the Related Art Under a multi-window system, a plurality of windows are managed by a window management table. The window management table stores attribute information such as the position and size of each window. . Then, a plurality of windows are controlled to be displayed on a CRT display by control based on the window management table. [0004] Under a conventional multi-window system, a window with a higher priority is displayed in front of other windows, so that its contents can be viewed. A window can be selected with a mouse cursor or the like to perform a predetermined process. However, a window with a low priority may be partially or entirely hidden by another window. [0005] Therefore, in the conventional multi-window, it may not be possible to grasp what window is displayed and how many windows are displayed on the display screen. Also, even if there is a window that is known to be displayed on the display screen, if the window is hidden by another window, the window cannot be pointed directly with a mouse cursor or the like. You can move the display position of other windows,
It was necessary to delete them, and a complicated operation was required to simply select a window. It is an object of the present invention to make it possible to easily perform a selection instruction for specifying a window displayed on a display screen. According to a first aspect of the present invention, there is provided a window information storage means for storing window information including display position information and size information regarding a window to be displayed on a display screen, When displaying the window on the display screen, a window is generated based on the window information stored in the window information storage means, and the generated window is displayed at a corresponding display position on the display screen. Window display means, and link setting means for generating a window marker corresponding to the generated window in conjunction with generation and display of the window, and setting link information to the window corresponding to the window marker. And the link information of the corresponding window is set by the link setting means. Array display means for arranging and displaying window markers in a predetermined display area in the display screen separately from the window displayed on the display screen, and display position instructing means for indicating an arbitrary display position on the display screen When the display position of the window mark arranged and displayed in the predetermined display area by the arrangement display means is selected and instructed by the display position instructing means, based on the link information set corresponding to the window sign. Window specifying means for specifying a window corresponding to the window mark. A second aspect of the present invention is a window display means for generating and displaying a plurality of windows in which display positions and sizes on a display screen are individually set in a superimposed display state according to the display priority of each window. In conjunction with the generation and display of the individual windows, window markers corresponding to the displayed individual windows are individually generated one by one, and the individual window markers and the windows corresponding to the window markers are generated. Link setting means for setting link information between, and an array display means for arranging and displaying in a predetermined display area in the display screen each window marker in which link information to a corresponding window is set by the link setting means, Display position indicating means for indicating an arbitrary display position on the display screen; and Of each window labeled arranged displayed in the display area, when the display position of the desired window indicator has been selected indicated by the display position indicating means
Window specifying means for specifying a window corresponding to the window marker based on link information set corresponding to the window marker. FIG. 1 is a system configuration diagram of a window selection device according to the present invention. In the figure, 11 is a mouse, 12
Is a keyboard. Mouse 11 or keyboard 1
An operation signal for controlling the screen of the CRT display 13, a window generation signal, a hard copy signal of the window to the printer 14, and the like are input from input devices such as 2.
The processor 15 is controlled according to a program (not shown) stored in a ROM. The processor 15
An input signal from the mouse 11 is received via the mouse controller 16 and an input signal from the keyboard 12 is received via the keyboard controller 17. Processor 1
Numeral 5 stores information relating to each window among the signals input from the mouse 11 or the keyboard 12 in the window management table 18 and stores the display data in the window memory 19. The window memory 19 stores window indicators for window selection, for example, icon data, which will be described later, in addition to the display data of the windows. In order to display overlapping windows on the CRT display 13, information on the position, size, attributes such as a pause flag, etc. and the relationship between windows is stored in the window management table 18, and the overlapping between windows is performed by a list structure. You need to manage state. FIG. 2 shows information stored in the window management table 18. Information in the window management table 18 includes window width bpw, window height bph, screen X coordinate bpx, screen Y coordinate bpy, character size csize, line pitch pitch, next window pointer fp, and previous window pointer. b
p, pointer swsp of the first subwindow, pointer swep of the last subwindow, pointer parent of the parent window, data titl of the title bar
e, a pointer atbp of the active title bar, a pointer dtbp of the inactive title bar, and a pointer iconp to the icon data. As shown in FIG. 3A, for example, when three windows winX, winY, and winZ are displayed on the screen in an overlapping manner, the processor 15
Creates a list structure between windows as shown in FIG. 3B based on a window generation signal from the mouse 11 or the keyboard 12. In FIG. 3B, the pointer swsp of the base window management table points to the first subwindow, that is, the window at the forefront of the screen, and the pointer sweep of the base window management table is the last subwindow, that is, the rearmost screen of the screen. Point to the window. FIG. 3 (a)
Like window winX, window wi
When nY is displayed on the last screen, the end mark NILL is first stored in the pointer bpx of the management table of the window winX and the pointer fpz of the management table of the window winZ in FIG. It is determined that the pointer bpx of the management table of the window winX and the pointer fpz of the management table of the window winZ are NILL, and the pointer swsp of the base window management table points to the management table of the window winX, and the pointer swe
A list structure is created so that p points to the management table of window winZ. The pointer fpx of the management table of window winX points to the management table of window winY, the pointer fpy of the management table of window winY points to the management table of window winZ, and the pointer bpy of the management table of window winY and the like. Point to the management table of window winX, and the pointer bpz of the management table of window winZ points to the management table of window winY, so that the windows winX, winY, winZ
Create a list structure between them. Window winX, wi
Pointer p of each management table of nY and winZ
arentx, parenty, and parentz point to the base window management table. When each window is displayed on the screen of the CRT display 13, control is transferred from the processor 15 to the overlap control device 20. Overlap control device 2
Numeral 0 is for creating control data for extracting information such as the display position of each window from the window management table 18, adjusting the display procedure, and displaying the information on the screen.
Also, the bit mover 21 is an overlap control device 20.
The display data of the window is taken out of the window memory 19 in accordance with the control data created in the above, that is, the display procedure, and is outputted to the CRT display 13. FIG. 4A shows, for example, that the windows winA and winB are displayed on the screen of the CRT display 13 in an overlapping state, the window winC is at rest, and the window winD is behind the window winA. This is a state that is hidden by the user. When a hard copy signal (not shown) is inputted from the mouse 11 or the keyboard 12 in this state, the processor 15 causes the window winA actually displayed from the window management table 18 to be described later in more detail. , WinB as well as the currently inactive window winC and the window winD hidden behind the window winA, for example, the icon display is indicated by the icon data pointers iconp1, iconp2, iconic of the window management table 18.
onp3, iconp4 (In the example shown in FIG. 3B, the icon data pointers iconpx, iconpy, and ic are respectively set in the windows winX, winY, and winZ.

Although iconp2, iconp3, iconp4 are not shown, windows winA, winB, win
C, winD (which is an icon data pointer), as shown in FIG. 4B, for example, on the lower side of the screen. Here, when one of these icons is selected with the mouse 11 or the keyboard 12, the control is transferred from the processor 15 to the hard copy control device 22. The hard copy control device 22 takes out the selected window data from the window memory 19, performs vertical / horizontal image conversion (not shown), and transfers control to the printer control device 23. The printer control device 23 sends the window data that has been converted to portrait / landscape to the printer 14, and
Prints window data.
In FIG. 1, the window management table 18, the window memory 19, the overlap control device 20, and the bit mover 21 constitute the hardware of the window display means 2, and the hard copy control device 22 constitutes the hardware of the window data selection means 3. And the printer control device 23 and the printer 14 constitute the output unit 4. The operation of the window selecting device having the above configuration will be described. A predetermined signal is input from the mouse 11 or the keyboard 12 and the CRT display 13
The description of the operation of displaying a window on the CRT display 13 is omitted because it has been described above, and the window win overlapping the CRT display 13 as shown in FIG.
A and winB are displayed on the screen, and the window win
In the case where the window winD is hidden behind A and a window winC is inactive, icons of all the windows winA, winB, winC, and winD are denoted by reference numerals 30, 31, 32, and 33 in FIG. As shown, the operation for displaying on the CRT display 13 will be described. A window wi is displayed on the CRT display 13.
nA and winB are displayed. When the window winD is hidden behind the window winA and the window winC is at rest, when a hard copy signal (not shown) is input from the mouse 11 or the keyboard 12, the processor 15 Starts an icon display program stored in a ROM (not shown). FIG.
It shows a flowchart of an icon display program. By executing this program, all windows winA, winB, winC, winD
Can be displayed on the CRT display 13. In the flow chart of FIG. 5, in step ST1, first, in order to search for the pointer to the icon data of the first window, the foreground A (FIG.
In the example shown in (b), the start address of the window management table of the window winA) is stored in the register P. Next, based on the start address position of the window management table pointed by the register P, a pointer iconp1 to the icon data of the window management table is stored in a predetermined position of the register r (step ST2). In this case, the pointer iconp1 to the icon data of the window winA is stored at the position of the first address of the register r. Next, in order to determine whether or not this window is the last window (this determination is made in FIG.
As shown in (b), this is done by paying attention to the fact that the end mark NILL is stored in the pointer fpz of the management table of the last window winZ. ) Pointer fp in window management table stored in register P
Is a termination mark NILL (step ST3). In this case, the first window winA is not the last window, and the end mark NILL is not stored in the pointer fp1 of its management table. Proceed to. In step ST4, the pointer fp1 in the window management table currently pointed to by the register P, that is, the head address of the window management table of the next window is stored in the register P. With this, Regis evening P is 2
The head address of the window management table of the second window winB is stored. Then, again at step ST
2, the window w is set based on the start address of the window management table pointed by the register P.
Pointer i to icon data in management table of inB
Comp2 is stored in the next address position of the register r. As a result, the pointer ico to the icon data of the window winB is located at the next address position of the register r.
np2 is stored. By repeating the above procedure, pointers iconp3, iconp4 to the icon data of the windows winC, winD are set at predetermined address positions of the register r.
Are sequentially stored. After storing the pointer iconp4 to the icon data of the window winD in the register r,
In step ST3, it is determined whether or not the pointer fp4 of the management table of the window winD is the end mark NILL. Since the window winD is the last window and the end mark NILL is stored in the pointer fp4, the pointers riconp1 and ico
The storage of np2, iconp3, iconp4 ends,
The process proceeds to step ST5 to display the icon on the CRT display 13. In step ST5, the register r
Pointer ic to the icon data sequentially stored in
onp1, iconp2, iconp3, iconp4
From each window winA, winB, win
The icon data storage position of C, winD is searched, and the icon data of each window is extracted from the icon data storage position and stored in, for example, the window memory 19, and is displayed on the CRT display 13 under the control of the bit mover 21 as shown in FIG. b) are displayed as indicated by reference numerals 30, 31, 32, and 33, and the icon display process ends. In this process, 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 the icon data. After the icons are displayed on the CRT display 13 in this manner, when the operator selects an icon for the window for which a hard copy is to be made with the mouse 11 or the keyboard 12, the processor 15 sends control to the hard copy control unit 22. Then, the hard copy selecting device 22 searches the window memory 19 for the display data of the window corresponding to the selected icon and extracts it. Then, the display data of the extracted window is converted into a vertical and horizontal image and transferred to the printer control device 23, which outputs the result to the printer 14. In the above embodiment, the CRT display 13
An icon is displayed as a window indicator of each window, and desired window data is printed on the printer 14 by selecting one of the icons from the mouse 11 or the keyboard 12. As a modification, the CRT is used. Instead of displaying the icons of each window on the display 13, the title bar of each window is displayed, and the operator selects one of the title bars from the mouse 11 or the keyboard 12 to print desired window data to the printer 14. You may make it do. By displaying the title bar on the CRT display 13, it is possible to select a desired window for which a hard copy is to be made without error even when a large number of windows exist. In the above embodiment, the hard copy signal is input from the mouse 11 or the keyboard 12 when displaying the icon data or the title bar data on the screen. After the window is displayed on the screen, icon data or title bar data may be automatically displayed on the screen without the intervention of the operator. According to the present invention, when a window whose display position and display size are set in advance on the display screen is generated and displayed, the window is generated and displayed in synchronization with the window generation and display. A window marker corresponding to the window is automatically generated and can be automatically arranged and displayed in a predetermined display area on the display screen. For the automatically generated window marker, the window marker is displayed. Since the link information to the corresponding window is also automatically set, the operator can immediately specify the window corresponding to the window marker by selecting the display position of the window marker.
