Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a window display method, and particularly to a window display method suitable for transitioning a work environment between a plurality of work environments.

[Conventional technology]

Traditional window display methods display multiple windows on a single screen and run applications on each window to create a specific work environment. In addition,
Related methods of this type include JP-A-60-2
No. 05492 and JP-A No. 60-254228.

[Problem to be solved by the invention]

In the above-mentioned conventional technology, a plurality of windows are opened on a CRT and a plurality of applications are operated to form one work environment. However, if you want to work in a different working environment than the current one, - degrees.

Close all windows (i.e. terminate all applications running on them),
It was extremely inconvenient to use because I had to open a new window to set up a new work environment. In other words,
A problem has arisen in that it is not possible to move to another work environment while temporarily suspending the current work environment (that is, temporarily saving the window state).

An object of the present invention is to solve the above problems.

[Means to solve the problem]

The above purpose is to maintain multiple window management records for each window whose elements are window display data (window display position and size) and pointers that connect each window display data according to display priority. This is achieved by providing a window management table and a work environment management table that holds a pointer to the window with the lowest display priority for each work environment.

[For production]

The above work environment management table holds, for each work environment, a pointer to the window with the lowest display priority in that work environment, and the above window management table holds window display data (window display position, size, etc.), and a pointer to the next window to be displayed after the window is displayed. Therefore 1
When a work environment is specified, the pointer to the window with the lowest display priority in the specified work environment can be obtained from the work environment management table, and then the pointer to the window with the lowest display priority can be obtained from the window management table. Windows can be displayed based on the display data of the lowest window. Furthermore, the display data of the window to be displayed primarily can be obtained by using the pointer to the window to be displayed primarily. Thereafter, the above process can be repeated until the window with the highest display priority is reached, and the specified work environment can be automatically created.

〔Example〕

An embodiment of the present invention will be described below with reference to FIG. FIG. 1 is a block diagram showing the overall configuration of the present invention. AP
The I display section 1400, the AP2 display section 1500, and the APn display section 1600 are display sections for applications such as word processors, spreadsheets, and graphs. Window management tape/Lz
1100 is a table that manages window display data such as the positions and sizes of multiple windows to be displayed on the VRAM 1700. Work environment management table I
Reference numeral 200 denotes a table that stores, for each work environment, a pointer on the window management table 1100 to the window with the lowest display priority in each work environment.

Here, configuration examples of the window management table 1100 and the work environment management table 1200 will be explained with reference to FIGS. 2 and 3. FIG. 2 shows the contents of the window management table. The display position of each window, corresponding to the row number of the table.

Window display data such as the size and type of AP operating on the window is stored. Furthermore, an FP pointer and a BP pointer are set to determine the display order of windows. The BP pointer stores the line number of the window whose display priority is one lower. The line number of the window with one higher display priority is stored in the FP pointer.This allows the FP pointer to be used to display the FP in the window display data when the line number of the window to be displayed first is specified.
By referring to the value of the pointer, the line number of the window to be displayed primarily can be determined. in this way,
By referring to the FP pointers one after another, windows can be displayed based on one display priority.

FIG. 3 shows the contents of the work environment management table. The work environment is set according to the row number of the table. Select the line number of the first window to be displayed from the window management table in Figure 2 and store that line number in the FP pointer.4 This allows you to select any work environment number from the work environment management table. Then.

Based on the FP pointer, the FP pointer on the window management table is followed, and one work environment is set.

Next, window display control will be explained using FIGS. 2 to 4. Figure 4 Working environment E1 display screen
Based on the window management table in Figure 3 and the work environment management table in Figure 3, work environment designation area 2, which is a screen displaying three windows API, AP2, and AP3, indicates the current work environment. Since E1 is currently selected, row number 1 in the work environment management table in Figure 3 is selected, and based on the value 1 of the FP pointer, the window display data of row number 1 in the window management table in Figure 2 is selected. is retrieved, the API is activated according to the AP type, and a window is displayed. Furthermore, based on the value 3 of the FP pointer of line number l on the window management table, the window display data of line number 3 is retrieved,
According to the AP type, AP2 is activated and windows are displayed in an overlapping manner. Thereafter, window display data is similarly retrieved and the window is displayed until the value of the FP pointer becomes -1.

Finally, from the work environment E1 display screen in Figure 4, work environment E
Regarding the control when switching the work environment to the two display screens, the window display control unit 1 will be explained using FIGS.
The processing contents of 000 will be explained.

First, the window display control unit 1000 activates the VRAM erasure unit 1300 to erase display data on the VRAM 1700. (1005 in Figure 5) Next, retrieve the relevant data from the work environment management table 1200 (1010 in Figure 5), retrieve the relevant window display data from the window management table 1100 (1015 in Figure 5), and then retrieve Based on the AP type in the window display data.

Selects the relevant AP display section from among the API display section 1400 to APn display section 1600 (FIG. 5 1025), sends window display data and starts the AP display section (FIG. 5 1030 to 1045). The AP display section generates display data based on the sent window display data, and sends it to VRA M170G and C.
Display a window on RT. Window display control section 1
000 is the FP on the window management table 1100 after sending the first window display data to the AP display unit.
Determine the value of the pointer (1050 in FIG. 5).

If the value is other than -1, the next window display data is retrieved based on the FP pointer (1055 in FIG. 5).

The above process is repeated until the end flag is turned on, thereby switching the work environment from El to E2.

〔Effect of the invention〕

As explained above, according to the present invention, it is possible to automatically migrate between a plurality of set work environments, so it is possible to interrupt one work, migrate to a new environment, or switch to an old environment. Returning can be done easily. Also.

Since it is possible to move to a new environment while retaining the relative positional relationship between windows at the time of interruption, when returning to the old environment, each window can be returned to the state at the time of interruption, improving usability.
