[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window display device for displaying a window on a display screen using a plurality of application programs, and more particularly to a window display device and a window display method capable of changing the window size.

[0002]

2. Description of the Related Art A GUI (graphical user interface) such as a window system which is characterized by an icon or multi-window screen display and an input operation of directly pointing a window or a menu with a pointing device is used to display various windows. Various operations are possible. For operations on windows, for example, "Iconize" that displays the window itself as an icon
There are "move" to change the display position of windows and "resize" to change the size of windows.

As shown in FIG. 9, the resizing operation for resizing the window is displayed on the resizing corner 101 displayed at each corner of the window display frame or on each side of the window display frame. Drag the mouse on the resized area 102 (move the mouse while holding down the mouse operation button to release the mouse operation button)
By performing an operation, or by clicking the resize button 103 displayed at a specific position of the window (holding down the operation button of the mouse and immediately releasing it), clicking the size of the window,
Alternatively, the window desired by the user can be displayed by displaying the window operation menu 105 by clicking or dragging the mouse, selecting a size change item from the menu items, and then performing a click operation indicating the size of the window. It is done by the method of inputting the size of. At this time, in order to visually present the size of the window that the user is about to input to the user, a virtual window display frame called a rubber band 104 indicating the size of the window after resizing is displayed. There are cases.

The size of the window display can be changed by such a size changing operation. Conventionally, the size changing operation is performed in the size changing operation for changing the size of the window. There are the following four types of changes in the display contents of the window after being opened.

1. As shown in FIGS. 10 (A) and 10 (B), the range of contents displayed changes as the frame of the window changes.

2. As shown in FIGS. 11A and 11B, the display magnification of the display content is enlarged or reduced according to the change of the window frame.

3. As shown in FIGS. 12A and 12B, only the frame of the window changes and the display content does not change.

4. As shown in FIGS. 13A and 13B, the window frame changes and the display content does not change, but it changes to fit the window frame.

The reason why such a difference occurs in the operation result despite the window resizing operation is that the corresponding processing after resizing differs depending on the application program (application program) displaying the window. Is.

Many of the above 1 and 2 are that the application program displaying the window when the size of the window is changed generates the display contents according to the new window frame, and 3 and 4 are the window. Window system or GU that displays a window at the request of the application program instead of the application program when the size of the window is changed
Most of I are re-displaying the display contents according to the new window frame. Therefore, although the user's input operation for resizing to change the size of the window display is the same for any application program window, the operation result differs depending on the application program.

[0011]

As described above, although the user's operation is exactly the same, the operation result differs depending on the application program. Therefore, before the user performs the operation of changing the size of the window, It is difficult to predict the operation result in advance, and the operation result of the size change tends to be different from the user's intention. If the operation result is different from the user's intention, the user is forced to perform a size change operation to restore the window size before the size change operation, which causes a problem that work efficiency is significantly reduced. In order to prevent the above-mentioned operation failures from occurring, it is necessary for the user to learn in advance how the window display contents will change as a result of the resizing operation for each application program. Yes, there is a large memory burden on the user and work efficiency is poor.

The present invention is for solving such a problem, and it is displayed with the window whether or not the window size changing operation by each application program involves changing the display contents in the window. A window display device and a window that can be posted to the user with or without a size change request instruction input unit, thereby eliminating the size change operation that the user does not intend and improving work efficiency. It is intended to provide a display method.

04).

Further, the window display control unit 22 determines whether or not the frame size of the application program 30 can be changed (step 205), and if the frame size can be changed, an instruction input unit for changing the frame size (first step). It is determined to add the frame size change corner 56, the frame size change area 57, and the frame size change button 55, which are the instruction input section, to the window frame (step 206).

Here, the window frame display data storage unit 2
6 has a window that can be resized, a window that can be resized, and a window that can both
Stores the display data of various window frames of windows whose size cannot be changed.

The window display control unit 22 sends the size of the window requested to be displayed and the determination in step 206 to the window display data generation unit 25, and the window display status storage unit 11 displays the window display coordinates and the window position. Record the display coordinates of the various buttons and the vertical relationship of the windows. FIG. 7 shows an example of recording the window display status stored in the window display status storage unit 11.

Next, the window display data generation unit 25 reads the display data of the window frame corresponding to the decision from the window frame display data storage unit 26, and inputs the size change instruction input unit having the requested size and based on the decision. Display data of a window frame having is generated (step 207).

Here, the window display data generator 25
Reads the display content of the window stored in the window display content storage unit 27 and generates display data of the content to be displayed in the window (step 208).

Then, the window display data generator 25
Sends the window frame and window display contents to the display drive control unit 33. As a result, the window of the application program 30 is displayed on the display device 34 (step 209).

FIG. 8A shows a display example of the application program of the "memo editor" when the window is displayed in this manner.

Now, the user operates the window displayed by using the keyboard 1 and the mouse 4, but when the user inputs the mouse 4 by dragging, the input operation of the mouse button by the user is Through the mouse I / O interface 5 and the mouse button depression detector 6, while the display position of the mouse cursor is via the X / Y coordinate detection unit 8, a menu display instruction detection unit 12, a total size change instruction detection unit 17, It is sent to the resizing control unit 18 and the frame size change instruction detecting unit 19. The menu display instruction detection unit 12 reads the display status of the window stored in the window display status storage unit 11 and determines whether the user's mouse drag is performed on the menu bar (menu display area) 59 shown in FIG. To do. Further, the all-size-change-instruction detection unit 17 reads the window display status stored in the window display-status storage unit 11, and determines whether or not the user's mouse drag is performed on the all-size change area 53 or the all-size change corner 52. To judge. In addition, the frame size change instruction detection unit 19 reads the display status of the window stored in the window display status storage unit 11, and whether the user's mouse drag is performed on the frame size change area 57 or the frame size change corner 56. Determine whether

On the other hand, when the user clicks and inputs the mouse 4, the user's mouse button input operation is the mouse I
/ O interface 5, mouse button depression detection unit 6
On the other hand, the display position of the mouse cursor is displayed on the menu display instruction detection unit 12, the total size change instruction detection unit 17, the resize control unit 18, and the frame size change instruction detection unit 19 via the X / Y coordinate detection unit 8. Sent. The menu display instruction detection unit 12 reads the display status of the window stored in the window display status storage unit 11 and determines whether the user's mouse click is performed on the menu bar (menu display area) 59. Further, the all-size change instruction detection unit 17 reads the display status of the window stored in the window display status storage unit 11, and determines whether or not the user's mouse click is performed on the all-size change button 51. Further, the frame size change instruction detection unit 19 reads the window display status stored in the window display status storage unit 11 and determines whether or not the user's mouse click is performed on the frame size change button 55 (step 210).

When the menu display instruction detection unit 12 determines that the user's operation is a menu display instruction, the determination result is sent to the menu display control unit 13. The menu display control unit 13 reads out the menu display items stored in the menu item storage unit 14 and sends them to the menu display data generation unit 15. The menu display data generation unit 15 reads the menu display data stored in the menu display data storage unit 16, adds the menu display items to generate the menu display data, and sends the menu display data to the display drive control unit 33. As a result, the display drive control unit 33 displays the window operation menu on the display device 34 (step 211).

At this time, release one of the menu items in which the next user operation is displayed (when the menu item is displayed by dragging the mouse button)
Or by clicking the mouse button (when the menu item is displayed by clicking the mouse button), the menu display instruction detection unit 12 determines that the user's operation is the menu selection instruction, and the determination result is menu display control. It is sent to the section 13 (step 212).

The menu display control unit 13 reads out the menu display item stored in the menu item storage unit 14 and determines whether or not the selected item has a lower item (step 213). Sends the contents of the menu display to the menu display data generation unit 15. If there is no subordinate item, it judges whether the selected item is the frame size change or the total size change, and the judgment result is the all size change instruction detection unit 17 Is sent to the frame size change instruction detection unit 19 (step 214).

When the total size change instruction detection unit 17 and the frame size change instruction detection unit 19 detect the user's instructions for the total size change and the frame size change, respectively, the resize control unit 18 is input with a new window size. Sends the name of the application whose window is being resized, as well as instructing it to accept the operation. If the user's operation input for instructing the size change is clicking a button or selecting a menu item, the user has released the mouse button, and the next operation is pressing the mouse button. On the contrary, when the user's operation to instruct the size change is to drag the button, the user keeps pressing the mouse button, and the next operation is to release the mouse button.

The resizing control unit 18, which receives the input instruction of the new size of the window from the all size change instruction detecting unit 17 and the frame size change instruction detecting unit 19, receives the data of the drag operation of the mouse 4 from the drag detecting unit 10. , It is determined whether or not the user's current operation is pressing down the mouse button. If the mouse button is not pressed, the mouse button is pressed (step 215).

When the mouse button is not pressed down, the rubber band 6 is formed into a rectangle having the upper left corner of the window as the starting point and the current position of the mouse cursor as the diagonal apex.
The rubber band display control unit 20 is instructed to display 0 (shown in FIG. 6). The rubber band display control unit 20 is X /
The current position of the mouse cursor is read from the Y-coordinate detection unit 8 and the rubber band display data generation unit 21 is instructed to generate the rubber band display data. The rubber band display data generation unit 21 sends the rubber band display data to the display drive control unit 33. As a result, the rubber band 60 is displayed on the display screen (step 216).

Subsequently, the resizing control unit 18 receives the data of the drag operation of the mouse 4 from the drag detection unit 10, detects that the user inputs the mouse button release, and the mouse button release input is received. When this is done, an instruction to erase the rubber band 60 is sent to the rubber band display control unit 20, and the window display control unit 22 is notified of the completion of the resizing operation and the display position of the mouse cursor when the mouse button is released. , And the application name of the window to be resized is sent (step 217).

When the window display control unit 22 receives the resize operation completion notification, the mouse cursor display position, and the application name of the window to be resized from the resize control unit 18, the resize operation storage unit 23. Whether or not the size change is possible and the corresponding operation after the size change, which are stored in, are read to determine whether or not the size change is possible. Then, the window display control unit 2
2 is if the application is resizable,
Instruction input section for changing all sizes (second instruction input section)
Total size change corner 52, Total size change area 5
It is decided to add 3 and the size change button 51 to the window frame.

Further, the window display control unit 22 determines whether the frame size of the application program 30 can be changed, and if the frame size can be changed, an instruction input unit for changing the frame size (first instruction input unit). It is decided to add the frame size change corner 56, the frame size change area 57, and the frame size change button 55 to the window frame.

After that, the window display control unit 22 sends the size of the window for which the display is requested and the determination to the window display data generation unit 25, and the window display condition storage unit 11 displays the window display coordinates, Record the display coordinates of various buttons on the window and the vertical relationship of the windows.

Next, the window display data generation unit 25 reads the display data of the window frame corresponding to the decision from the window frame display data storage unit 26, and inputs the size change instruction based on the decision with the requested size. Display data of a window frame having a copy is generated (step 218).

The resizing control unit 18 judges whether the instruction to input the new size of the window is sent from the all-size-change-instruction detection unit 17 or the frame-size-change-instruction detection unit 19, and whether the size change is the frame size change or all. It is determined whether the size is changed (step 219). When the window size changing operation input by the user is a frame size changing operation, the resizing control unit 18 reads out the corresponding operation after the size change stored in the size change corresponding operation storage unit 23, and determines the frame size of the application. The corresponding action after the change is determined (step 220).

For example, the corresponding operation after changing the frame size of the memo editor is to redisplay the display contents by the processing of the application program as shown in FIG.

Further, the resizing control unit 18 instructs the window display control unit 22 to notify the application program 30 of the size change when the corresponding operation after the size change of the application is the correspondence by the application. The window display control unit 22 communicates the new size of the window to the application program 30 via the application communication unit 28 (step 222).

Then, the window display control section 22 instructs the application program 30 via the application communication section 28 to retransmit the display data of the application (step 223).

Upon receipt of this instruction, the application program 30 transmits to the application communication section 28 a window display request consisting of the size of the window and the contents displayed on the window. The application communication unit 28 uses the window display data writing unit 29 to display the content displayed in the window, and the window display content storage unit 2
Write to 7. Then, the window display data generation unit 2
Reference numeral 5 reads the window display contents stored in the window display content storage unit 27 and generates display data of the contents to be displayed in the window (step 224). The window display data generation unit 25 sends the window frame and the window display content to the display drive control unit 33. As a result, FIG.
As shown in (B), only the size of the window frame is changed and displayed (step 227).

On the other hand, when the window size change operation input by the user is a total size change, the resize control section 18 reads the corresponding operation after the size change stored in the size change corresponding operation storage section 23, The corresponding operation after the frame size of the application is changed is determined (step 22).
1).

For example, in the memo editor, as shown in FIG. 5, the corresponding operation after changing the total size is to display the window display contents again.

When the corresponding operation after the application is resized is not supported by the application, the resizing control unit 18 notifies the window display control unit 22 of the window size and character font change. The window display control unit 22 determines the character font from the correspondence between the size of the new window and the type of character font stored in the character font display data storage unit 24 (step 225), and the window display data generation unit 25
Instruct to create window display data. The window display data generation unit 25 reads the display contents of the window stored in the window display content storage unit 27 and the character font stored in the character font display data storage unit 24 (step 226), and displays the display data of the contents to be displayed in the window. To generate. Then, the window display data generation unit 25 sends the window frame and the window display content to the display drive control unit 33. As a result, as shown in FIG. 8C, the size of the window frame and the character font in the window are simultaneously changed and displayed (step 227).

Thus, according to the window display resizing apparatus of this embodiment, regarding the application program for which the window display request has been made, whether the window displayed by this application program can be resized or not and the corresponding operation after the resize are shown in FIG. The size change corner 52, which is determined based on the information stored in the size change handling operation storage unit 23 shown in FIG. 5, and serves as an instruction input unit (second instruction input unit) for changing the entire size if the entire size can be changed. A frame size change corner that adds an all size change area 53 and an all size change button 51 to the window frame and, if the frame size can be changed, serves as an instruction input unit (first instruction input unit) for changing the frame size 56, a frame size change area 57 and a frame size change button 55 are added to the window frame. Therefore, the user can know in advance from the presence or absence of the display of these instruction input units what kind of operation result will be obtained when the size changing operation is performed on the window being displayed. Therefore, the size change operation which is not intended by the user can be eliminated, and the work efficiency can be improved.

In this embodiment, as the application program for displaying the window, the frame size is changed (only the window frame is changed) to redisplay the display contents by the processing of the application program, and the window without the processing of the application program is changed. Using the application program "memo editor (memoedit)" that creates a memo document that can resize the two windows by redisplaying the display buffer and changing the total size (simultaneously changing the window frame and window display contents). As described above, the entire size is changed to redisplay the display contents by the processing of the application program (simultaneous change of the window frame and the display contents of the window), and the frame is redisplayed in the display buffer of the window without the processing of the application program. It is obvious that the result of the resizing can be easily predicted even in another application program capable of resizing the two windows of resizing (changing only the window frame).

Further, in the present embodiment, the display of the instruction input unit (second instruction input unit) for changing the total size and the instruction input unit (first instruction input unit) for changing the frame size
Although it is configured so that the corresponding action after the size of the displayed window is changed can be seen, the information indicating the corresponding action stored in the size change action storing unit 23 is directly replaced with the visible information and is posted to the user. You may As a result, the user can obtain at least the minimum information for predicting the result after the size of the window being displayed is changed, and the same effect as that of the previous embodiment can be expected.

[0074]

As described above, according to the window display device and the window display method of the present invention, it is possible to determine whether or not the window size changing operation by each application program involves changing the display content in the window.
It can be posted to the user with or without the instruction input section for the size change request displayed together with the window.
It is possible to prevent a size change operation different from the user's intention and improve work efficiency. Moreover, the user does not need to learn in advance how the display content of the window changes for each application program by the size changing operation, and the memory burden on the user can be reduced.
