When the child window extends out of the parent window, the coordinate position is changed and input again, and the same procedure as above is repeated.

FIG. 5 is a flowchart for moving the parent window.

As can be seen from the figure, in order to move the parent window, first, the window to be moved is specified.

That is, the window to be moved is designated by the mouse, the coordinates of the position are output by the input coordinate output unit 16, and this is sent to the target window specifying unit 18, and then the target window specifying unit 18 makes the above-mentioned coordinates. Using, the window stored in the window management information storage unit 17 is searched for the window displayed at this coordinate position and is sent to the window moving unit 15.

Next, the target window is moved to a desired position with the mouse.

When the specified window is the parent window, the window moving unit 15 receives the coordinate position of the movement destination of the parent window from the input coordinate output unit 16 and calculates the amount of movement from the original position. At the same time, the original coordinate data of the parent window stored in the window management information storage unit 17 is sequentially updated with the new coordinate data.

Next, the coordinate data of the corresponding child window is read from the window information storage unit 17.

Next, the window moving unit 15 calculates coordinate data after the child window is moved so that the child window moves by the same amount as the parent window, and the calculated data is stored in the window management information storage unit 17. The stored original coordinate data of the child window is sequentially updated.

Then, based on the updated coordinate data, graphic data is created in the same manner as described with reference to FIG.
Display on the display 11.

When it is desired to continue moving the parent window, the above procedure is repeated.

FIG. 6 is a flow chart when the specified window is a child window.

The window moving unit 15 receives the coordinate position of the destination of the child window from the input coordinate output unit 16, while reading the coordinate data of the corresponding parent window from the window management information storage unit 17.

To search for the corresponding parent window, the window specifying information (for example, the ID number in FIG. 3) from the target window specifying unit 18 may be used.

Then, the protrusion determining unit 19 determines whether the child window does not protrude from the corresponding parent window at the coordinate position of the movement destination.

In case of protruding, the coordinate position of the moving destination is changed and input again.

If it does not stick out, the original coordinate data of the child window stored in the window management information storage unit 17 is updated with the coordinate data of this destination.

Then, based on the updated coordinate data, graphic data is created in the same manner as described with reference to FIG.
Display on the display 11.

When it is desired to continue moving the child window, the above procedure is repeated.

When the parent window is moved to overlap another parent window and child window which have already been generated, for example, the moving parent window is prioritized, and the overlapping area is changed to another parent window. And it is better not to display child windows.

Similarly, when a child window is moved to overlap another child window that has already been created, for example, the moving child window is given priority, and another child window is displayed in the overlapping area. It is better not to.

As described above, according to the image display device of this embodiment, the child window is generated in the corresponding parent window and its movement is restricted within the parent window.

When the parent window is moved, the corresponding child window is also moved.

Therefore, even when a plurality of sets of windows are displayed on one display, it is possible to easily know which parent window the child window corresponds to.

Therefore, the operator can perform the window operation quickly and efficiently.

Further, since each set of windows can be independently operated by different input sections, if each operator operates each input section, one display can be treated as a plurality of displays. This enables the image display device to be used efficiently.

In the present embodiment, a mouse is provided for each group, but one window may be used to operate all windows.

Further, the window processing unit of the present embodiment configures each set of windows as a parent window and a child window. However, the windows making up each set have a predetermined relationship with each other, and the windows of other sets are different from each other. The same operation as described above can be performed in all cases in which it is desired to identify on the display.

For example, the windows forming each set may be windows having an equal relationship.

In this case, the same operation as described above can be performed by treating one of the sets as a parent window for convenience.

Further, the window processing unit of the present embodiment includes a window generation unit capable of determining the display position of a child window so that a predetermined child window is generated in a corresponding parent window, and a predetermined child window. , Provided with a window moving unit capable of deciding the display position of the child window so as to move within the corresponding parent window and along with the movement of the parent window, but limited to such a configuration Instead, the display position of the child window may be determined such that the child window is displayed at a display position having a predetermined relative relationship with the display position of the corresponding parent window on the display.

Therefore, for example, the child window may be generated near the corresponding parent window.

Furthermore, the window processing unit of the present invention is not limited to such a configuration, and may create windows so that each set of windows can be identified on the display.

For example, the windows may be created so that the windows are displayed on the display in different display colors for each set.
