Abstract

PURPOSE:To improve operation circumstances of a window by changing the thickness of a window frame and validating the select indication of a cursor to a position in a prescribed length or shorter distant from the frame before the elapse of a certain time at the time of moving the window frame on a display picture. CONSTITUTION:At the time of expanding/reducing a window 2 in a state (a), a cursor 4 is moved to a window frame selectable area 5. A window frame 3 has the same thickness as the area 5 as shown by a state (b) to indicate that selection is possible. Though the cursor 4 is moved out of the area, selection is possible when a prescribed time does not elapse yet. The button on a mouse is depressed to move the cursor thereafter, thereby expanding or reducing the frame 3 in accordance with movement of the cursor s shown by a state (c). Finally, the cursor 4 is stopped in an arbitrary position, the button is released and the thickness of the frame 3 is restored to the original thickness at the time of elapse of the prescribed time after movement to the outside of the area 5, and the picture in a hidden area is drawn again, thus completing expansion/reduction of the window 2.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a method for controlling the display of a window when enlarging or reducing a window by moving a window frame in a multi-window system.

[Conventional technology]

The prior art will be explained using FIGS. 2(a) to 2(d).

In FIG. 2, 1 is the display screen of the display device (hereinafter referred to as the display screen), 2 is the display area (i.e. window), 3 is the frame (hereinafter referred to as window frame), and 4 is the indicated position of the pointing device. It is a mark (hereinafter referred to as a cursor).

Conventionally, in order to enlarge or reduce the window 2 in the state shown in FIG. 2(a), first, when the cursor 4 is moved onto the window frame 3, the cursor 4 is moved to 5 as shown in FIG. 2(b). The shape of the cursor 4 changes to indicate that window frame 3 can be selected. Next, select the window frame 3 by pressing the mouse button, for example, and move the cursor 4 to an arbitrary position. As shown in FIG. The image is enlarged or reduced according to the movement of the image.

Finally, as shown in FIG. 2(d), if you stop the cursor 4 at a desired position and deselect the window frame 3 by pressing the mouse button, for example, you can enlarge or enlarge the window 2. Reduction is complete.

Note that "selecting" a window frame refers to the act of not only indicating the window frame by positioning the cursor, but also expressing the intention to make the window frame follow the cursor in order to enlarge or reduce the window. , in this case corresponds to holding down the mouse button.

[Problem to be solved by the invention]

In the above-mentioned conventional technology, the selectable range of window frames is limited to seven frames of the window. Further, the window frame can be selected only when the cursor is on the window frame. Therefore, sophisticated pointing device operations were required to select the window frame. It is also possible to make the window frame thick all the time to make it easier to select the window frame, but in this case the display area becomes narrower.

Furthermore, in the conventional technology, the fact that a window frame is selectable is indicated by changing the shape of the cursor, so if you are not paying attention to the cursor, you cannot tell whether the window frame is selectable or not. The problem was that there was no.

An object of the present invention is to facilitate the selection of a window frame without reducing the display area, and to clearly indicate whether or not a window frame can be selected by changing the thickness of the window frame, thereby allowing window operations. The goal is to improve the environment.

[Means to solve the problem]

In order to achieve the above object, a display screen control method according to the present invention displays a window on the display screen of a display device, and in a display screen control method that enlarges or reduces the window, the frame of the window is adjusted using a pointing device. When selecting and moving a window, the thickness of the frame is changed to indicate that the window in question can be selected.

According to another aspect, the display screen control method according to the present invention has the following features:
A screen of a display device in a computer system is divided into one or more individual display areas or overlapping display areas, and each of the display areas corresponds to one or more programs running in parallel on the computer system. In a display screen control method that outputs a display to By changing the thickness of the frame of the area, it is displayed that the display area is selectable.

In these display screen control methods, preferably, when the indicated position of the pointing device is within the frame and within a predetermined distance from the frame, the frame can be selected.

Furthermore, after the pointing position of the pointing device leaves the selectable range of the frame, the frame may be made selectable for a predetermined period of time.

[Effect]

The present invention facilitates the selection of a window frame by expanding the window seven frame selectable range and/or extending the window frame selectable period.

Also, by changing the thickness of the window frame to indicate that the window frame can be selected,
Easily confirms window frame selection.

〔Example〕

An embodiment of the present invention will be described below with reference to the drawings.

FIGS. 1(a) to 1(d) are diagrams showing how a window is enlarged (according to one embodiment of the present invention).

In the figure, 1 is a display screen and 2 is a window.

3 indicates a window frame, 4 & sentence cursor, and 5 a window frame selectable area.

In the state shown in FIG. 1(a), in order to enlarge or reduce the window 2, first move the cursor 4 to the window 7 frame selectable area 5, and as shown in FIG. The thickness of frame 3 becomes, for example, the same thickness as window frame selectable area 5, indicating that window frame 3 is selectable.

After this, even if the cursor 4 moves out of the window frame selectable area 5, the window frame 5 remains unchanged for a predetermined period.
is selectable. After this specified period,
Window frame 3 becomes unselectable and returns to its original thickness. At this time, the area hidden under the thicker frame 5 of the window 7 will be redrawn.

Next, if you move the cursor 4 to an arbitrary position while keeping the window frame 6 selected, for example by pressing the mouse button, the window frame 5 will follow the cursor 4, as shown in Figure 1 (0). The image will be enlarged or reduced.

Finally, as shown in Figure 1(d), if you stop the cursor 4 at a desired position and deselect the window frame 3, for example by releasing the mouse button, the drawing will be redrawn in the window 2 area. is carried out.

Then, after a predetermined period has elapsed since the cursor 4 was moved outside the window frame selectable area 5, the thickness of the window frame 3 returns to the original thickness), and the enlargement or reduction of the window 2 is completed. At this time, the area hidden under the thickened window frame 3 will be redrawn.

Next, an example of a method for extending the selectable period of window frame 3 will be described.

FIG. 3 is a flowchart of a routine that is activated at predetermined intervals, for example, by a timer interrupt.

This routine extends the selectable period of window frame 3. First, in step 6, cursor 4
It is determined whether or not the position is inside the window frame selectable area 5. If it is inside, selection of window frame 3 is permitted in step 7, and a counter is set to 'N1 in step 8. If it is not inside, it is determined whether the counter is "0" or not in step 9, and if it is "0", selection of the wind frame 5 is prohibited in step 10, and '
If it is not 0, the counter is decremented by 1 in step 11.

As a result, after the cursor 4 leaves the window frame selectable area 5, the window frame 3 can be selected for a period that is N times the interval at which this routine is activated.

〔Effect of the invention〕

As explained above, according to the present invention, the selectable area of the window frame is wide (and the selection can be made for a while even if the cursor leaves the selectable area), making it easy to select the window frame. become. Also,
Whether or not a window frame is selectable is indicated by changing the thickness of the window frame regardless of the change in the shape of the cursor, so there is no need to always pay attention to the cursor. Since the width of the window 7 frame becomes thicker only when the window frame is selectable, the display area does not become narrower.

According to the present invention, window operability can be improved as described above.
