Since the conventional window system is configured as described above, when the pointing device is moved with respect to the window being displayed on the screen, the window becomes difficult to see due to the display of the mouse cursor. As a mouse cursor movement event occurs for the application corresponding to the window, there is a problem that the processing speed of the application decreases.

In particular, when the window is displaying a moving image or the like, the display of the moving image is disturbed by the mouse cursor, and the real time display of the moving image cannot be maintained due to the occurrence of the mouse cursor movement event, which is an obstacle to the moving image display. I will end up.

The present invention has been made in order to solve the above-mentioned problems, and it is possible to set or release the restriction on the movement of the cursor within each window displayed on the display means, so that the window can be released. An object of the present invention is to provide a window system and a window display method capable of preventing a screen display defect due to execution of an event process accompanying the movement of the cursor inward.

[0009]

In a window system according to the present invention, an instruction means for instructing a cursor movement and a setting for individually setting a cursor movement condition into a display window for each window that can be displayed on the display means. Means, management means for storing and managing cursor movement conditions into the display window for each window set by the setting means, and cursor movement instruction by the instruction means based on the cursor movement conditions managed by the management means. And a control means for controlling the movement of the cursor into each display window.

In the window display method, the cursor movement to each display window associated with the cursor movement instruction is individually controlled with reference to the cursor movement condition to each display window set for each window.

[0011]

In the window system of the present invention, when the cursor moving condition into the display window is individually set for each window that can be displayed on the display means by the setting means, the managing means sets each window. The cursor movement condition to the display window is stored and managed, and when the cursor movement to each display window occurs by the instruction means, the control means controls the cursor movement instruction based on the cursor movement condition managed by the instruction means. By controlling the cursor movement into each display window due to
It is possible to effectively limit the movement of the cursor into the window that causes display failure.

Further, the window display method is performed by individually controlling the cursor movement into each display window according to the cursor movement instruction while referring to the cursor movement condition into the display window set for each window. Even if the cursor movement is instructed to each displayed window, it is possible to individually prohibit the cursor movement into the display window.

The same reference numerals are attached to the same components.

In the figure, reference numeral 2 denotes an input control unit which corrects the input data based on the input data from the input unit 1 such as a pointing device and the information in the window information table 4 and outputs it to the window control unit 3 or the window. It controls the output to the control unit 3.

In the window system thus constructed, the cursor moving condition into the display window is individually set for each window that can be displayed on the display unit (window display unit 5) by the setting unit (input unit 1). When set to 1, the management means (window information table 4) stores and manages the cursor movement condition into the display window for each set window, and the pointing means (input unit 1) moves the cursor into each display window. When the movement occurs, the control unit (window control unit 3) controls the cursor movement into each display window according to the cursor movement instruction by the instruction unit based on the cursor movement condition managed by the instruction unit, thereby causing a display failure. It is possible to effectively limit the movement of the cursor into the window that accompanies.

Further, the window display method is performed by individually controlling the cursor movement into each display window in accordance with the cursor movement instruction while referring to the cursor movement condition into the display window set for each window. Even if the cursor movement is instructed to each displayed window, it is possible to individually prohibit the cursor movement into the display window.

FIG. 2 is a diagram showing an example of the window information table 4 shown in FIG.

As shown in this figure, the window control section 3 has a window number 11, an upper left coordinate 12, and a lower right coordinate 1.

On the other hand, if the determination in step (1) is NO, when a cursor display cancellation request is input from the input section 1 to the window of the program area 7-1, that is, a prohibition flag setting request has already been made. The cursor display prohibition flag 16 is ON. It is determined whether or not a cancellation request has been made for the prohibition flag (2). If NO, the process returns. If YES, the cursor display prohibition flag 16 is turned OFF (4). To return.

In this way, the cursor display prohibition flag 16 can be set / released individually for each window, and the cursor display prohibition flag 16 is set when executing the cursor movement control based on the flowchart shown in FIG. The movement of the mouse cursor can be controlled from the state.

FIG. 4 is a flow chart showing an example of a cursor movement processing procedure in the window system according to the present invention. Note that (1) to (9) indicate each step.

First, when a cursor movement instruction is given by the pointing device of the input unit 1 (1), the outer frame (see FIG. 5) of the window W1 displayed on the screen of the window display unit 5 is moved by the mouse cursor K1. It is determined whether or not it is instructed (2), and if NO, the position information currently instructed by the cursor is output to the window control unit 3 (5), and the mouse cursor is moved and displayed on the screen following the operation of the pointing device. (6) Return.

On the other hand, if the judgment in step (2) is YES, the input control unit 2 refers to the window information table 4.
(3) It is determined whether or not the cursor display prohibition flag 16 corresponding to the instructed window is set to the ON state (4). If YES, the process is ended, and if NO, the cursor movement instruction is given by the pointing device. Cod
(7) The position information is output to the window controller 3 (8), and the mouse cursor is moved and displayed in the displayed window W1 following the operation of the pointing device (9).
, Return. As a result, when the cursor display prohibition flag 16 of the window W1 is set to the ON state, even if the pointing device is moved, the operation shown in FIG.
As shown in, the mouse cursor K1 is prohibited from moving from the outer frame of the window W1 to the inside, and other processing,
For example, it does not affect the moving image display processing.
Further, it is possible to prohibit the internal movement of the mouse cursor for each window, and it is possible to effectively eliminate the deterioration of the visual recognition of information associated with the display of the mouse cursor in the window.

In the above embodiment, the case where the movement of the mouse cursor into each window in which the mouse cursor is displayed is controlled based on the cursor display prohibition flag 16 has been described.
Even a window system in which subordinate windows are displayed within each window can be easily dealt with by increasing and managing the number of cursor display prohibition flags 16 on the window information table 4.

[0028]

As described above, according to the present invention, the management means is set when the condition for moving the cursor into the display window is individually set for each window that can be displayed on the display means by the setting means. The cursor movement condition to the display window is managed for each window, and when the cursor movement to each display window is caused by the instruction means, the control means controls the cursor movement condition based on the cursor movement condition managed by the instruction means. Since the cursor movement into each display window according to the movement instruction is controlled, it is possible to effectively limit the cursor movement into the window which causes a display failure.

In the window display method, the cursor movement to each display window in response to the cursor movement instruction is individually controlled while referring to the cursor movement condition to each display window set for each window. With the configuration, even if the cursor movement is instructed to each displayed window, the movement of the cursor into the display window can be individually prohibited.

Therefore, it is possible to limit the movement event process activation by the pointing device to the window of the application for which the real-time property must be maintained, and it is possible to effectively prevent the screen display failure and the like due to the reduction of the processing speed of the application. Further, it is possible to eliminate the display obstruction to the in-window information due to the cursor display in the window, and it is possible to significantly improve the visibility of the window information.
