By specifying any one of 0, the page change to the previous page of the window screen is selected, and by specifying any of the areas B11 and B12, the page change to the next page of the window screen is selected. (2) Operation The microprocessor unit 11 informs that the display item of the window is selected from the screen editing menu and that one window is selected from the following menu by the value of the cursor pointer 12 and the switch-on operation of the mouse. When it is recognized, the window width signal generation circuit 17, the priority circuit 18, and the offset memory 19 are respectively controlled, and the designated window is displayed on the CRT display 1.
Display output to 3. That is, the window width signal generation circuit 1
7 is a CR under the control of the microprocessor unit 11.
The window width signal is output at the display timing of the window to be displayed in synchronization with the synchronization signal from the T controller 15. This window width signal is input to the priority circuit 18. The priority circuit 18 determines a priority order based on overlapping windows to be displayed under the control of the microprocessor unit 11,
The window width signal received from the window width signal generation circuit 17 is selectively output according to the priority order. The window width signal output from the priority circuit 18 is supplied to an offset memory 19. The offset memory 19 outputs an offset address of the window in synchronization with the window width signal received from the priority circuit 18. The offset address is input to the adder 20 together with the display address output from the CRT controller 15, and the offset address of the display target window is added to the display address. The display address output from the adder 20 is given to the RAM 14 via the address selector 16. As a result, the read address of the RAM 14 is switched from the main display area to the window display area each time the display timing of the window to be displayed is reached, and during that time, the data in the window display area is changed to the CR.
The window is sent to the T display 13 and a designated window screen in the main screen including the window change menu is displayed. FIG. 3A shows a display screen displayed on the CRT display 13 at this time, and FIG. 4A shows data correspondence in the RAM 14. Here, from the window change menu, for example, to change the window size, if the area of [size] is designated by the operation of moving the mouse cursor, the area designation is recognized by the microprocessor unit 11. When recognizing the designation of the change in the window size, the microprocessor unit 11 displays the [size] area in an inverted display state and also displays the display data of the window frame display area around the window in the main display area of the RAM 14 in the RAM 14. The frame data is temporarily evacuated to a predetermined non-display area, and the frame data is written in that area. This gives C
On the RT display 13, a window screen to which a window frame (F) is added is displayed. FIG. 3B shows a display screen displayed on the CRT display 13 at this time, and FIG. 4B shows data correspondence in the RAM 14. Next, a cursor movement operation of the mouse causes
The command area in the window frame (F) is designated according to the size change. That is, when changing the fixed size of the window, one of the areas “L”, “D”, “M”, and “S” shown in FIG. 6 in the area A3 of the window frame (F) is designated by the cursor. I do. For example, by selecting “L”, the maximum screen (720 horizontal dots (45 characters) × 920 vertical dots)
Dots (46 lines)), and by selecting “D”, the default screen (688 dots horizontal (43 characters) × 90 vertical dots)
0 dots (45 lines)), selecting “M” results in an intermediate screen (352 dots (22 characters) × 460 dots (23 lines)), and selecting “S” results in a minimum screen (horizontal). 96 dots (6 characters) x 120 dots (6
Line)). When the size of a part of the window is changed, the area (L, D,
Other areas (A1 to A8) except for (M, S) are designated by the cursor. That is, when the size in the horizontal direction is changed, the area A in the window frame (F) is moved by moving the mouse cursor.
1 and A2 to change the size in the vertical direction, specify one of the areas A3 and A4 in the same frame by the same operation as described above, and change the size in the vector direction to the area A5. , A6, or A7, A8. In FIGS. 3 and 4, either A1 or A2 is designated, the mouse is turned on, and the mouse is moved in that state. Here, since the size is changed in the horizontal direction, the mouse is moved in the horizontal direction. The operation direction at this time does not need to be right beside, and may be an oblique direction (vector direction). The microprocessor 11 sequentially reads signals accompanying the switch operation of the mouse and the movement of the cursor, recognizes the designated direction of the window size and the amount of change, and each time the output signal width of the window width signal generation circuit 17 is output. And variably controls the window area according to the amount of movement of the mouse. Thereby, CRT display 1
The horizontal size of the window displayed on the display screen 3 changes with the movement of the mouse. FIG. 3C shows a display screen displayed on the CRT display 13 at this time, and FIG. 4C shows data correspondence in the RAM 14. When the predetermined window size is reached, the switch-on state of the mouse is released and the mouse is turned off, whereby the state is recognized by the microprocessor 11. The microprocessor 11 recognizes that the operation of changing the size of the window has been completed by turning off the mouse. Thereafter, the area of the [size] is selected again by the mouse cursor moving operation, and the mouse switch is turned on, thereby canceling the display of the window frame (F) and the window frame (F) on the display screen. Is erased, the saved data of that part is read out and returned to the main screen display, and the window whose size has been changed is displayed on the display screen together with the window change menu shown in FIG. The display mode is such that the window can be changed. In the above description, the change of the horizontal size of the window has been described as an example. For example, when the size is changed in the upper left or lower right direction on the display screen, the area A of the window frame (F) is changed.
The mouse may be moved in the vector direction by designating 5, A6 with the cursor, and when changing the size in the upper right or lower left direction on the display screen, the window frame (F)
It is sufficient to move the mouse in the vector direction by designating the regions A7 and A8 of the window with the cursor, and to change the size in the vertical direction on the display screen, move the regions A3 and A4 of the window frame (F) with the cursor. You can move the mouse up and down by specifying. To move the window in an arbitrary direction, the user may select a "move" area from the window change menu and then operate the mouse in the same manner as in the case of the size change. That is, for example, when moving the window in the left-right direction, the user may specify the areas A1 and A2 of the window frame (F) with the cursor and operate the mouse in the left-right direction.
When the window is to be moved up and down, the user can specify the areas A3 and A4 of the window frame (F) with the cursor and operate the mouse up and down.
Alternatively, when moving the window in the lower right direction, the user may specify the areas A5 and A6 of the window frame (F) with the cursor and operate the mouse in the vector direction. When moving the window in the upper right or lower left direction, Area A of window frame (F)
7. A8 may be designated by the cursor and the mouse may be moved in the vector direction. When moving this window screen,
Microprocessor unit 11 with mouse movement
The offset value of the display target window in the offset memory 19 is rewritten under the control of. These operations,
Since the processing means and the processing means can be easily understood from the above-described size changing processing operation, the description of the operation is omitted here. When scrolling the window screen in an arbitrary direction, select a region of [Scroll] from the window change menu by moving the mouse cursor.
Window frame (F) shown in FIG. 6 displayed on the display screen
After selecting a desired scroll direction from, the mouse switch is sequentially turned on each time scrolling is performed. That is, for example, when scrolling the window screen sequentially in the left and right direction, one of the areas B1, B2 or B3, B4 of the window frame (F) shown in FIG. When the window screen is scrolled up and down sequentially, one of the areas B5, B6 or B7, B8 of the window frame (F) is designated by the cursor, and the mouse switch is scrolled. Operate each time. When sequentially switching the window screen to the previous page, after designating the area B9 or B10 of the window frame (F) with the cursor, the user sequentially turns on the mouse switch every time the page is switched, and sequentially switches the window screen to the next page. When switching to a page, the area B11 of the window frame (F)
Alternatively, after specifying B12 with the cursor, the mouse switch may be sequentially turned on each time the page is switched. The window frame (F) shown in FIG. 6 is erased by selecting the [Scroll] area again from the window change menu and turning on the mouse switch. As described above, the window change menu and the window frame (F) on the display screen are respectively designated by the mouse, so that various window changing operations can be performed easily and quickly. In the above-described embodiment, the window is surrounded by the window frame (F), and the command area is divided within the frame. However, the present invention is not limited to this. A display form in which a command designation area is provided in part may be used. In the above embodiment, menu selection and item selection are all performed by using the mouse, but the invention is not limited to this, and other input means may be used. According to the present invention, display or non-display of an instruction area for instructing scroll display of display contents displayed in a window display screen can be performed as required by a selection instruction on a selection display menu. The display can be switched arbitrarily.
