Next, the operation of the virtual space window management system of this embodiment constructed as described above will be explained.

When the virtual space window 62 is generated as a child window of the root window 61, the control unit 8
Clearing the coordinates (x, y) of the display frame 63 of the display range storage unit 2, the size of the display frame 63 (width, height)
And the initial setting such as storing the size (width, height) of the display frame 63 in the display range storage unit 2 and generating and displaying the layout change menu window 64 and the end menu window 65 respectively (step S41). It should be noted that 1 is set in the not_move_flag of the arrangement information storage unit 1 of the virtual space window 62.
Is set (flagged).

Next, the control section 8 calls the arrangement state display means 5 (step S42).

The arrangement state display means 5 first obtains the virtual space range (-X, -Y) to (X, Y) which are system fixed values (step S51), and whether the arrangement information storage unit 1 exists. It is determined whether there is a target window based on somehow (step 52).

If there is a target window, the layout status display means 5 displays the virtual space coordinates (x, y) and size (width) of the target window from the layout information storage unit 1.
h, height) is obtained (step S53), and the reduced display coordinates ((x-(-X)) / 1 of the virtual space window 62 are obtained.
0, (y-(-Y)) / 10) to the size (width /
(10, height / 10) displays a reduced image of a window that is the target of (height / 10) (not a window other than the arrangement change mode), and not_move_fla
A color indicating that the window cannot be moved is added to the reduced image of the window in which g stands (step S54).

Subsequently, the arrangement state display means 5 obtains the virtual space coordinates (x, y) and the size (width, height) of the display frame 63 from the display range storage unit 2 (step S55), and the virtual space window 62. Reduced display coordinates ((x-(-X)) / 10, (y-(-Y)) / 10)
A display frame 63 of size (width / 10, height / 10) is displayed on the screen (step S56).

The arrangement state display means 5 performs steps 52 to 5 until the target window in step S52 is exhausted.
When 6 is repeated and the target window is exhausted, the control is returned to the control unit 8.

The control unit 8 determines whether or not there is a click event in the virtual space window 62 (step S43). If there is a click event in the virtual space window 62, the current position of the display frame 63 is changed to the mouse cursor position. This means that the window moving means 3 is called in order to change the display position of the reduced image of the window in the display frame 63 (step S4).
4).

The window moving means 3 first displays the display frame 6
The virtual space coordinate (x, y) after the movement of 3 is calculated, and the value is stored in the display range storage unit 2 (step S61).

Next, the window moving means 3 judges whether or not there is a target window based on whether or not the layout information storage section 1 exists (step S6).
2), if there is a target window, not_move
It is determined whether _flag is not standing (step 63). The window moving means 3 uses not_move
If _flag is set, control is returned to step 62,
If not_move_flag is not set, the virtual space coordinates (x, y) of the window from the arrangement information storage unit 1
And the size (width, height) are obtained (step S64).

Subsequently, the window moving means 3 determines whether or not the target window is within the display frame 63 (step S65), and if it is within the display frame 63, the target window is displayed. To call the window display routine (step S66).

On the other hand, if it is not in the display frame 63, the window moving means 3 displays the target window in the display frame 6.
The window non-display routine is called in order to move the window 3 to the outside so as not to display the window (step S67).

Step S65 (and step S12
In determining whether the window of 4) is within the display frame 63, the window moving means 3 determines the display range storage unit 2
The virtual space coordinates (x, y) and the size (width, height) of the display frame 63 are acquired from (step S7).
1), virtual space coordinates (x, y) and size (width, height) of the window from the layout information storage unit 1
Is obtained (step S72), the magnitude relationship between the lower right corner position of the display frame 63 and the upper left corner position of the window is compared (step S72), and the magnitude relationship between the upper left corner position of the display frame 63 and the lower right corner position of the window is compared. (Step S7
3) It is determined whether the window is inside the display frame 63.

Step S66 (and step S12
In the window display routine of 5), the window moving means 3 uses the virtual space coordinates (x, y) of the display frame 63 and the virtual space coordinates (x = wx, y = wy) of the window to display coordinates (wx-x) of the window. , Wy−y) is calculated (step S 81), and the window display coordinates (wx−
(x, wy-y) (step S82).

Step S67 (and step S12
In the window non-display routine of 6), the window moving means 3 obtains the coordinates (x, y) and judges whether the window has been in the display state on the root window 61 until now (step S91), and the display state up to now. If so, the window is moved to the outside of the display frame 63 (step S92).

When the window is moved out of the displayable range, the displayable range of the screen of the display device 6 becomes (0,0).
It is in the range of (width, height), and it is used that the window is not displayed even if the window is moved to any other position. For example, (0,0) to (600,90
If 0) is in the displayable range, the window is
0,1200), the window will not be displayed on the root window 61 of the display device 6.

Further, the control section 8 judges whether or not there is a click event in the layout changing menu window 64 (step S45), and if there is a click event in the layout changing menu window 64, the window can be moved. Since this means the setting of the arrangement change mode, the arrangement change means 4 is called (step S46).

The layout changing means 4 first determines whether or not there is a target window based on whether or not the layout information storage unit 1 exists (step S101), and if there is a target window, the system changes. Virtual space ranges (-X, -Y) to (X, Y) that are fixed values are obtained (step S1).
02).

Next, the layout changing means 4 determines whether or not there is a window in which the reduced image window is not generated and displayed based on whether or not there is a value in sw of the layout information storage unit 1 (whether it is 0 or not). (Step 103), and if there is a window in which the reduced image window is not generated and displayed, the virtual space coordinates (x, y) and size (width, heig) of the window are displayed from the arrangement information storage unit 1.
ht) (step S104), and the reduced display coordinates ((x − (− X)) / 10, (y of the virtual space window 62.
-(-Y)) / 10) to the size (width / 10, h
A reduced image window of height / 10) is generated and displayed, and a value (0
Other than) is set (step S105). At this time, n
If it is a window in which ot_move_flag is standing, the arrangement changing unit 4 adds a color indicating that the reduced image window cannot be moved.

Subsequently, the arrangement changing means 4 sets the event selection in the reduced image window (step 10).
6).

Steps S103 to S106 are repeated until there are no windows for which reduced image windows have not been generated and displayed in step S103. When there are no windows for which reduced image windows have not been generated and displayed, the layout changing means 4 causes each reduced image window to be displayed. Determines whether or not there is a mouse event (step S11).
1) If there is no mouse event, it is determined whether or not the layout change mode has been switched based on whether or not there is a click event in the layout change menu window 63 (step S112). The arrangement changing means 4 returns the control to step S111 if the arrangement changing mode is not switched, destroys all the reduced image windows generated for releasing the arrangement changing mode if the arrangement changing mode is switched, and arranges the arrangement information. Sw of the storage unit 1 is set to 0 (step S115).

If there is a mouse event in the reduced image window in step S111, the layout changing means 4 determines whether it is a left drag (step S113), and if it is not a left drag, it is a right click (step S114). ).

If left dragging in step S113,
The arrangement changing means 4 moves the reduced image window so as to follow the mouse cursor (step S121) and determines whether or not the button is released (step S12).
2). If it is a button release, the arrangement changing means 4 determines the position as the movement destination, and the virtual space coordinates (-X + x * 1) of the window corresponding to the reduced image window.
0, -Y + y * 10) is calculated and substituted into the virtual space coordinates (x, y) of the window layout information storage unit 1 (step S123).

Next, the arrangement changing means 4 determines whether or not the window located at the changed virtual space coordinates (x, y) is in the display frame 63 (step S124). For example, the window display routine is called (step S125). On the other hand, if it is outside the display frame 63, the arrangement changing means 4 calls the window non-display routine (step S126).

If it is a right click in step 114, the arrangement changing means 4 determines whether or not not_move_flag is set (step S131), and not_
If move_flag is not standing, not_mo
ve_flag is set to 1 and a color indicating that the reduced image window cannot be moved is added (step S13).
2). On the other hand, if not_move_flag is set, not_move_flag is set to 0, and the color of the reduced image window is returned to the original color indicating that it can be moved (step S133).

FIG. 14 is a diagram showing a specific display example of the virtual space window 62. In the virtual space window 62, reduced images of windows A, B, C, D and E and a display frame 63 are displayed. At this time, the window actually displayed in the root window 61 is
Only the windows A and B that include the reduced image in the display frame 63. Now, assume that windows B and C are to be displayed on the root window 61. then,
The user places the mouse cursor on the upper left position of the reduced image of the window B in the virtual space window 62 and clicks the mouse button (YES in step S43).
Then, after the window moving means 3 is called to move the window on the root window 61 (step S44), the arrangement state display means 5 causes the reduced image of the window on the virtual space window 62 and the display frame 63.
Are moved (steps S54 and S56). As a result, as shown in FIG. 15, the display of the window A on the root window 61 disappears, and the windows B and C are displayed on the root window 61 (step S82).

Next, assume that the user wants to change the layout position of the window in the virtual space. For example, assume that the position of the window A shown in FIG. 14 is to be changed to the position of the window A shown in FIG. At that time, the user positions the mouse cursor on the layout change menu window 64 and clicks the mouse button (YES in step S45). Then, the arrangement changing means 4 is called (step S4
6) After the reduced image window is changed to the placement change mode for selecting an event (step S106), after placing the mouse cursor on the reduced image window of the window A and clicking (YES in step S111),
When the mouse cursor is moved while pressing the left mouse button, the reduced image window of the window A moves following the mouse cursor (step S121).
If the left mouse button is released at the position of the window A shown in FIG. 16 (YES in step S122), the position at that time becomes the position of the window A (step S123).
Window A is displayed at the position shown in 6 (step S
82).

The virtual space window management system is terminated by positioning the mouse cursor on the termination menu window 65 and clicking the mouse button (step S49). Then, the virtual space window 62 on the root window 61 is destroyed and the process returns to the conventional multi-window system processing by the control unit. At this time, if there are windows outside the display frame 63, a warning is issued and all the windows are returned to the display frame 63 by the user, or all the windows are forced to be displayed by the virtual space window management system. It is better to finish after returning to 63.
