Description

[Detailed Description of the Invention] [Summary] The present invention relates to a screen scrolling method using a layout screen in which a graphic screen larger than a display screen is scrolled using a reduced size layout screen. For the purpose of scrolling the screen, the frame position of the layout screen is detected and converted to the coordinate position on the entire display screen, and when the frame of the layout screen is moved using an operating means such as a mouse, the detected entire display The screen information for one screen is read out based on the converted position coordinates on the screen and displayed on the display screen.

[Industrial Field of Application] The present invention relates to a screen scrolling method that uses a layout screen to scroll a graphic screen larger than a display screen using a layout screen.

CAD, paint systems, etc. handle graphic screens that are larger than the display size, and as the graphic screen becomes larger, the proportion of the display screen to the entire graphic screen decreases. In such cases, there is a need for a technology that easily and quickly cuts out a necessary portion from the entire graphic screen and displays it on a display.

[Prior Art] FIG. 8 is an explanatory diagram showing a conventional screen scrolling method.

In FIG. 8, reference numeral 30 denotes a CPU as a controller, and the CPU 30 is provided with an entire screen graphic memory 16 that stores the entire graphic screen.
The data in the area corresponding to the screen is transferred to the main screen display memory (frame memory) 14 and displayed on the main screen 12 of the display device 10 by a dedicated CRT controller. Further, 22 is a layout screen memory (frame memory), which stores data obtained by read access using a predetermined spacing address corresponding to the reduction ratio in order to display the information in the entire screen graphic memory 16 in a reduced size. A layout screen 20 is displayed, for example, at the lower left position of the main screen 12, and within the layout screen 20, a frame 18 indicating the current display position of the main screen 12 is displayed.

The conventional screen scrolling method for such a graphic display is that the windows 34-1 to 34- of the main screen 12
When the scroll bar 4 is clicked, for example, with a mouse, quantitative scrolling is performed to move the contents of the graphic screen on the main screen 12 in a preset direction by a predetermined amount.

[Problems to be Solved by the Invention] However, in such a conventional quantitative scrolling method, even if the desired position to be displayed on the layout screen is known, quantitative scrolling is necessary to move the frame to the displayed position. There were cases where the user had to repeat the process several times, which caused the problem that the operation was complicated and it took a long time to scroll to the desired position.

For example, in a Gantt chart graphic display that can display only 1/16th of the main screen or the entire screen (1/4 height x 1/4 width), you can scroll the main screen from the left edge of the Gantt chart to the right edge. requires three page scrolls.

In addition, although you can check on the layout screen where work is concentrated in the Gantt chart, it was necessary to perform quantitative scrolling several times to accurately display that area on the main screen.

The present invention has been made in view of such conventional problems, and an object of the present invention is to provide a screen scrolling method using a layout screen that allows the main screen to be easily and quickly scrolled from the layout screen to an area desired to be displayed. do.

Is displayed.

FIG. 4 is an operation flow diagram showing screen scroll control of the present invention in the embodiment of FIG. 2.

First, use the mouse 24 or keyboard 38 to
When the PU 30 is instructed to display a layout, the processing flow shown in FIG. 4 is executed, and in step S1 (hereinafter, "step" is omitted), the layout screen 20, which is a reduced display of the entire graphic screen, is displayed on the main screen as shown in FIG. At the same time, a frame 18 indicating the position of the main screen 12 currently displayed is displayed in the layout screen 20.

Subsequently, in S2, it is checked whether there is an instruction to end the layout display, and if there is no instruction to end the display, the process proceeds to S3, where the position of the frame 18 in the layout screen 20 is detected. The position of this frame 18 is detected as the position on the entire graphic screen stored in the entire screen graphic memory 16.

Next, the process advances to S4, and it is determined whether the position of the frame 18 detected in S3 is different from the current position of the main screen 12. If it is different, the main screen 12 is scrolled, and the entire graphic corresponding to the frame 18 is Display the screen position.

FIG. 5 is an operational flow diagram showing in detail the frame position detection and main screen scroll processing shown in steps 83 to S5 of the operational flow diagram of FIG. 4.

In FIG. 5, first, the position of the frame 18 is detected at S31 and S31.
It will be held at 32. That is, at 831, first layout screen 2 is displayed.
The starting point coordinates (Xi, Yi) of the frame 18 displayed within 0 are detected.

For example, taking the layout screen 20 shown in FIG. 6 (+a) as an example, the layout screen 20 initially shows a frame 18 shown in ■, and when this frame 18 is moved to the position of the frame 18' shown in ■. shall be.

For example, if the lower right corner of the layout screen 20 is the origin O, the starting point coordinates at the position marked ■ in the frame 18 are the starting point coordinates (Xi
, Yl). Regarding the frame 18' after the movement, the position coordinates (X2.Yl) are detected in the same way.

Next, the process proceeds to 832, where the starting point coordinates (Xi, Yi) of the frame 18 of the layout screen 20 are converted into coordinates of the entire graphic screen.

This coordinate transformation is performed as follows.

If the horizontal and vertical sizes of the layout screen 20 in FIG. 6(a) are (W1, Hl), the starting point coordinates of the frame 18 (Xi, Y
l) is first normalized by the size of the layout screen 20 and converted into normalized coordinates (Xi/Wl) (Yi/H1). However, in this case, i=1.

Next, the entire graphic screen 16a shown in FIG. 6(b)
Let the horizontal and vertical sizes of the frame 18 be (W2.H2), then multiply each of the normalized start point coordinates of the frame 18 of the layout screen 20 by the value of the size (W2.H2) of the entire graphic screen 16a, and match the frame 18. Full graphic screen 16
Find the starting point coordinates (x, y) on a.

Similarly, for the frame 18' indicated by ■ on the layout screen 20 after the movement, the starting point coordinates (X, Y) of the frame 18' on the entire graphic screen 16A can be determined.

Next, the process proceeds to 84, where it is determined whether the coordinate position of the frame starting point coordinates (x, y) on the entire graphic screen detected in S32 is different from the coordinates of the starting point position on the entire graphic screen of the main screen 12 currently displayed. If the starting point position coordinates of the two are different, the process proceeds to S5, and data for one screen is read from the entire screen graphic memory 16 from the conversion starting point coordinates (x, y) of the frame 18 detected in S32. This allows the main screen 12 to be transferred to the main screen frame memory 14 and rewritten, thereby performing a scroll process of switching the main screen 12 to the display in the frame 18 at a different position, that is, the display in the moved frame 18.

7A, 7B, and 70 are screen explanatory diagrams showing a specific embodiment of the scrolling device according to the present invention, taking the graphic display of a Gantt chart as an example.

In FIG. 7A, only the main screen 12 is displayed, and an operation message including a layout display is shown in the window 52 above the main screen 12, and the cursor 50 is moved to the mouse 24 as shown. When you move to the layout display part and perform a click operation, the layout display is reversed in black and white, and the layout screen 2 shown in Figure 7B is displayed.
The display state changes to 0.

In addition, in FIG. 7A, in addition to the numbers on the quantitative scroll bars of the windows 34-1 to 34-4 on the lower and right sides of the screen 12, there are also numbers in the four windows 48-1 to 48-4. A window 34- in which a scroll bar for continuous scrolling is displayed, and a scroll bar for quantitative scrolling in diagonal up and down directions is further displayed in the lower right corner.
5 is provided.

When the display is switched to the layout screen 20 shown in FIG. 7B, a frame 18 indicating the current display position of the main screen 12 is displayed in the layout screen 20.

If you want to scroll the main screen 12 in the display state shown in FIG. 7B, for example, as shown in FIG.
When the cursor 50 is placed inside and moved by operating the mouse 24, the frame 18 also moves following the cursor 50 as shown in FIG. 7C.

As this frame 18 moves, a positional shift occurs between the frame 18 and the main screen.
Frame 1 has been scrolled and moved as shown.
The display switches to the main screen 12 showing the entire graphic screen of 8. Therefore, in one operation using the layout screen 20, any position on the entire graphic screen can be moved to the main screen 1.
2 can be scrolled.

Of course, as in the conventional method, quantitative scrolling is also possible as shown in FIG. It is possible to perform quantitative scroll display on this screen by scrolling.

In the above embodiment, a specific example of the graphic display of the Gantt chart was shown, but the present invention is not limited to this, and can be applied to any appropriate system that scrolls and displays a graphic screen larger than the main screen of the display. Can be applied. Further, in the above embodiment, scrolling is performed by operating a mouse, but it goes without saying that an appropriate operating means such as a light pen or a touch display may be used.

[Effects of the Invention] As explained above, according to the present invention, large scrolling on a graphic screen or scrolling to an arbitrary position can be easily and quickly performed with a single mouse operation, and the operator can The effort can be significantly reduced.
