Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window system control technique and an information processing technique, and more particularly to a technique effectively applied to control of a window system in an information processing device such as a personal computer or a workstation.

[0002]

2. Description of the Related Art It has become common to employ a window system having a graphical user interface as basic software for information processing devices such as personal computers and workstations.

In such a window system, a conventional window system is used, as described in, for example, Japanese BP, published on June 21, 1995, "Latest Personal Computer Technology 795" P98. Then, at the left and bottom edges of the window, the X axis (left and right) respectively
A scroll bar for scrolling in the Y-direction and the Y-axis (up and down) direction is arranged. When scrolling the display data, the mouse pointer is moved to the corresponding scroll bar for each axis direction, and the scroll bar in the scroll bar is moved. It has been practiced to operate the cursor to individually control the direction and amount of scrolling.

[0004]

In the above-mentioned prior art,
There is a technical problem that the operability is inferior because it is necessary to move the mouse pointer onto the scroll cursor every time scrolling in each of the X and Y axis directions. In particular, in the scroll movement in the diagonal direction, it is necessary to individually perform both operations of the X and Y axes, which further lowers the operability, and when looking at the drawing operation in the window,
Once the image data of the moving destination is drawn at the moving end in one axis direction, and then the drawing operation at the moving end of the other axis is required, which increases the load on the graphic drawing processor during scroll movement. However, there is a technical problem that the scroll speed also decreases.

Furthermore, since the scroll bar is always displayed on the edge of the window, the display range of the normal image data is narrowed by the display area of the scroll bar, and the availability of the display and the window is reduced. There is also a technical problem.

It is an object of the present invention to provide a window system control technique capable of improving the operability in scroll movement within a window.

Another object of the present invention is to provide a window system control technique capable of improving the speed of scroll movement within a window.

Still another object of the present invention is to provide a window system control technique capable of improving availability of a display area of a display.

SUMMARY OF THE INVENTION Among the inventions disclosed in the present application, the outline of a representative one will be briefly described.
It is as follows.

That is, the present invention selectively displays a part of display data of an arbitrary size through the first window, and scrolls or jumps the display screen in the first window to display the display data. In the control method of the window system that can display an arbitrary area,
The scroll movement or the jump movement is controlled at the position of the pointer cursor located at an arbitrary position in the first window.

Further, according to the present invention, a display for visualizing and outputting display data, an input means for inputting information, and a part of the display data of an arbitrary size are set in the screen of the display. Is selectively displayed through the window of the first window, and any area of the display data can be displayed by scrolling or jumping the display screen in the first window, and any area in the screen of the display can be operated by the operation of the input means. In a data processing device including a window system having a pointer cursor positioned at the position, the scroll movement or the jump movement is controlled at the position of the pointer cursor at an arbitrary position in the first window. It is a thing.

More specifically, for example, when scrolling is required in the first window, a specific key operation or mouse button operation defined in advance is used as a trigger to move the mouse pointer to the current mouse pointer position. The moving window as the second window is displayed, and the scroll movement in the first window is controlled by moving the mouse pointer in the moving window.

According to the present invention, since the moving window is displayed at the position where the mouse pointer is currently located and the direction and amount of scroll movement can be designated, the mouse is always added to the scroll bar provided at the edge of the window as in the conventional case. The operation such as positioning the pointer is not necessary at all, the number of times of operating the keys and the mouse is reduced, and the operability particularly when the scroll movement is performed in the diagonal direction is significantly improved. Further, in the case of the diagonal scroll movement, the number of unnecessary redraws of the image data in the first window is reduced as compared with the case where the scroll is performed for each of the X and Y directions. The speed of the entire scroll movement can be improved accordingly. Further, it is not always necessary to arrange the scroll bar at the edge of the first window, and the first window can be widely used by that amount,
Improves display availability.

In the following description, scroll movement will be described for simplicity, but jump movement can be realized in the same manner.

A scroll bar 2 in the Y-axis direction and a scroll bar 3 in the X-axis direction are displayed at the right end and the lower end of the window system 1 of FIG. 1, respectively. It is not always necessary to realize the scroll movement in FIG. 1 and is shown for convenience of comparison with the prior art.

That is, in this embodiment, the moving window 4 displayed on the window system 1 is used instead of the conventional scroll bars 2 and 3. Since the display coordinates of the moving window 4 are currently determined centering on the coordinate value at which the mouse pointer 6 is located, there is no need to perform an operation such as positioning the mouse pointer 6 at a specific position in the window system 1. Inside the moving window 4, a circular moving area 5 composed of a plurality of concentric circles 5a to 5c centering on the initial position of the mouse pointer 6 is displayed. The minimum gauge circle 5a forming the circular movement area 5 is
For example, the radius is 25 dots (pixels), the middle gauge circle 5b has a radius of 50 dots, and the outermost gauge circle 5c has a radius of 50 dots. Give a measure of. The scroll direction is determined by the moving direction of the mouse pointer 6 with respect to the center of the circular moving area 5. Then, in order to actually scroll the display screen 1a in the window system 1, the mouse pointer 6 is moved in an arbitrary direction in the circular movement area 5 in the movement window 4 by an arbitrary distance to move the movement destination. Base point 7 of window system 1
This is performed by obtaining the (logical) coordinate value of (display data 10).

An example of the operation of the window system control method and the information processing apparatus of the present embodiment will be described below with reference to the flow chart of FIG.

First, a specific key 61 or button 71 (hereinafter, referred to as a scroll start key)
It is monitored whether or not the scroll start key (generically referred to as a scroll start key) is pressed (step 201), and when it is pressed, the coordinate value (Xk, Y) of the current base point 7 of the window system 1 is monitored.
k) is obtained (step 202), and the current coordinate value (Xm, Ym) of the mouse pointer 6 is obtained (step 203). Then, the moving window 4 is displayed at the current coordinate value (Xm, Ym) of the mouse pointer 6 (step 204). At this time, the current mouse pointer 6
The moving window 4 is drawn so that the coordinate values (Xm, Ym) of the moving window 4 coincide with the center of the circular moving area 5 of the moving window 4, and the current position of the mouse pointer 6 is automatically changed to the circular moving area 5 It is in a state that matches the center of the.

Further, the movement of the mouse pointer 6 in the movement window 4 and the pressing of a specific key 61 or button 71 (hereinafter collectively referred to as a confirmation key) for confirming the scroll designation are monitored (step 205, step 2).
06).

When the pressing of the enter key is detected,
From the difference between the current coordinate value (Xm ', Ym') of the mouse pointer 6 in the moving window 4 and the first coordinate value (Xm, Ym), the movement amount ΔXm, ΔYm of the mouse pointer 6 is calculated.
(The sign represents the moving direction) is calculated (step 20
7) Further, the moving amount ΔXm, ΔYm of the mouse pointer 6 is added to the coordinate value (Xk, Yk) of the current base point 7 to obtain the coordinate value (Xk ′, Yk ′) of the base point 7 of the moving destination (step 208), the coordinate value (Xk ', Y of the base point 7 of the movement destination)
At k '), the scroll movement is completed by redrawing the display data 10 and setting the moving window 4 in the non-display state (step 209).

As described above, in the case of the present embodiment, since the moving window 4 can be output to the current position of the mouse pointer 6 and the scroll direction and amount of both the X and Y axes can be designated at the same time, the conventional method is used. In comparison with the case where the scroll bar 2 and the scroll bar 3 are individually operated for each of the X and Y axes, particularly, the keyboard 60 and the mouse 70 by the operator in the scroll movement in the diagonal direction.
Since the operation amount of is reduced, the operability is improved. Also,
In the diagonal scrolling, it is not necessary to redraw the display screen 1a of the window system 1 for each scroll end of each of the X and Y axes as in the related art, which reduces the load on the drawing system and reduces the scroll speed. It is possible to improve.

Further, in FIG. 1, the conventional scroll bar 2 and the scroll bar 3 are displayed for convenience of description, but by using the moving window 4, the display of the scroll bar 2 and 3 can be omitted, and the scroll concerned. The display area of the display screen 1a in the window system 1 can be expanded by the width of the bars 2 and 3, and more of the display area can be used to output the original display data 10.
It is possible to improve the availability of.

(Second Embodiment) FIG. 3 is a flow chart showing an example of the operation of the control method for the window system according to the second embodiment of the present invention. In the example of the flowchart of FIG. 2 described above, the display screen 1a of the window system 1 is in a static state until the re-drawing at the moving destination is performed by pressing the enter key, but the mouse pointer 6 in the moving window 4 By sequentially updating the display screen 1a in association with the displacement, it is possible to perform scrolling in real time in conjunction with the movement of the mouse pointer 6.

That is, as illustrated in the flowchart of FIG. 3, when the scroll start key is pressed (step 301), the current coordinate value of the mouse pointer is acquired (step 302), and the position of the mouse pointer is set. The moving window 4 is displayed so that the centers of the circular moving areas 5 coincide with each other (step 303). After that, the displacement of the mouse pointer 6 is monitored (step 304), and when the displacement is detected, the movement amount of the mouse pointer 6 is acquired (step 30).
5) Further, the coordinate value of the base point 7 of the window system 1 is acquired (step 306), and the coordinate value of the destination base point 7 is calculated from the movement amount of the mouse pointer 6 and the current coordinate value of the base point 7 (step 306). 307), and redrawing the moving destination of the window system 1 (step 308). The operations of steps 304 to 308 are repeated until depression of the enter key is detected (step 309). That is, in this case, the mouse pointer 6 inside the moving window 4
In response to the movement, the screen of the window system 1 is updated in real time while the moving window 4 is still displayed. When the pressing of the enter key is detected, the used moving window 4 is hidden (step 3
10) The scroll operation is completed.

In the case of the second embodiment illustrated in the flow chart of FIG. 3, the display screen 1a of the window system 1 is updated in real time following the displacement of the mouse pointer 6 in the moving window 4, Scrolling display screen 1 although the drawing system load is heavy

That is, the moving window 8 illustrated in FIG. 4 displays the reduced image 10 a of the entire display data 10, and the current relative position of the window system 1 inside the reduced image 10 a is displayed by the window mark 9. As a result, the operator can immediately know where in the entire display data 10 is output on the display screen of the window system 1. In addition, inside the moving window 8, the entire reduced image 10a of the display data 10 is displayed as X.
And a gauge 8a that equally divides in the Y direction is output,
It gives a guideline for the scroll amount when the window mark 9 is moved as described later.

An example of the operation when the moving window 8 shown in FIG. 4 is used will be described below with reference to the flowchart shown in FIG.

When the depression of the scroll start key is detected (step 501), the coordinate value of the current base point 7 of the window system 1 is acquired (step 502), and further the current coordinate value of the mouse pointer 6 is acquired (step 502). Step 50
3). Then, the moving window 8 is displayed at the current position of the mouse pointer 6 (step 504). At this time, the display position of the moving window 8 is determined so that the position of the mouse pointer 6 coincides with an arbitrary corner portion of the window mark 9 displayed inside the moving window 8. Thus, the operation of searching for the window mark 9 in the moving window 8 and matching the mouse pointer 6 is omitted.

After that, when the movement of the mouse pointer 6 is detected (step 505), the movement amount of the mouse pointer 6 is acquired (step 506), and the movement destination of the mouse pointer 6 is followed inside the movement window 8. like,
The outline of the window mark 9 is displayed by, for example, a broken line (step 507). The operations of steps 505 to 507 are executed until pressing of the enter key is detected (step 5
08).

When the confirmation key is pressed down,
Window system 1 acquired in step 502
From the coordinate value of the base point 7 and the moving amount of the mouse pointer 6 inside the moving window 8, the coordinate value of the moving base point 7 is calculated (step 509), redrawing is performed at the moving destination of the window system 1, and scrolling is performed. The operation is complete (step 510). At this time, the used moving window 8 is hidden.

During the loop of steps 505 to 507 in the flowchart of FIG. 5, the coordinate value of the base point 7 in step 502 is obtained, the coordinate value of the base point 7 of the moving destination in step 509 is calculated, and further, the window system 1 is used.
By redrawing at the destination of the movement, the display screen 1a of the window system 1 can be displayed in real time following the displacement of the mouse pointer 6 inside the movement window 8 as in the case of the flowchart illustrated in FIG. It is also possible to scroll.

In the case of the third embodiment, the reduced image 10 of the entire display data 10 is displayed inside the moving window 8.
