Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scroll bar display control system, and more particularly to word processing software, and assigns page numbers with a page break width according to the amount of documents in a screen displaying document data consisting of a plurality of pages. The present invention relates to a scroll bar display control system that controls display by installing the guide portion on the scroll bar.

[0002]

2. Description of the Related Art Conventionally, when controlling the display of a document data consisting of a plurality of pages by a scroll bar, by displaying the boundary line and page number of each page on the scroll bar, it plays a role of scale. Since the line is calculated based on the total number of pages in the document data, it has a uniform division width regardless of the document amount of each page, and the relative position on the document data can only be recognized by the scroll box.

[0003]

As described above, in the conventional control system, the page break width is calculated based on the total number of pages of the document information. Therefore, in displaying the page number on the scroll bar, The boundary of each page is divided with a uniform division width. Therefore, by using the page number displayed on the scroll bar as a guide, the scroll box can be displayed by dragging the scroll box near the page number desired by the user. However, since the page numbers on the scroll bar are divided by the uniform division width, there is no visual effect of grasping the approximate document amount of each page by the scroll bar.

[0004]

The scroll bar display control system of the present invention receives information from an input device,
A means for designating the timing for controlling the scroll bar, a means for calculating the page break width according to the amount of documents on the scroll bar, and a guide part provided with page numbers with the page break width are installed on the scroll bar. And means for doing so.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the present invention, FIG. 2 is a flow chart showing a processing procedure of a page break width ratio calculating device in the embodiment of FIG. 1, and FIG. 3 is a page addition in a scroll bar control device. 4 is a flowchart showing a processing procedure for calculating the guide portion, FIG.
Is a flow chart showing a processing procedure for searching the relative position of the scroll box in the document on the scroll bar.
FIG. 6 is an image diagram of the page break width ratio calculation and a scroll bar provided with a guide portion.

The scroll bar display controller shown in FIG. 1 has an input device 101 for receiving information on mouse and keyboard operations, a user opening a document file, proofreading a document, and dragging a scroll box on the scroll bar with a mouse. The input control device 102 for controlling the timing when clicking on the scroll bar
And a data management device 103 that manages the data of the page number in the document data, the coordinates of the last line of each page and the coordinates of the scroll bar rectangle, and the data of the break coordinates on the scroll bar calculated by the page break width ratio. Further, a page break width ratio calculating device 104 for calculating the page break width ratio at the timing from the input control device 102, and a guide portion provided with page numbers at the calculated ratio are installed beside the scroll bar, and It is composed of a scroll bar control device 105 for searching and controlling the relative position of the scroll box in the document, and an output device 106 for outputting to the CRT based on the information. Since the document amount of each page used in the page break width ratio calculation is based on the display height calculated from the last line coordinate of the page, the data management device 103 manages the document information.

Next, the processing procedure for calculating the page break width in the page break width ratio calculating device 104 will be described with reference to the flowchart shown in FIG. 2 and the image diagrams shown in FIGS.

When the document file is opened, when the document is proofread, the page break width ratio calculation device 1 is required by the information from the input control device 102 that needs to calculate the page break width ratio.
First, in step 201, the total number of pages 04, and the coordinates of the first line and the last line of the document data of each page are displayed in the data management device 103
Get more. Next, in step 202, step 201
The display height on the page is calculated from the difference between the last row coordinate and the first row coordinate acquired. Y1, y2, y shown in FIG.
3 and y4 show images of this display height. In steps 203 and 204, the display height is accumulated up to the last page of the document, and the result is used as the total page display height. Y in the image 601 shows an image of this total page display height. In step 205, y1, y2
Each of y3 and y4 is divided by the total page display height Y calculated in step 203 to calculate the page break width ratios y1 / Y, y2 / Y, y3 / Y, y4 / Y shown in the image 602, and step 206 To store that information.

Next, the process of calculating the page giving guide portion in the scroll bar control device will be described with reference to the flowchart shown in FIG. 3 and the image diagram shown in FIG.

In step 301, the coordinates of the scroll bar rectangle are acquired from the data management device 103, and the height H of the scroll bar rectangle shown in the image 603 is calculated accordingly. In step 302, the page break width ratio is obtained from the data management device 103, and in step 303, the scroll bar rectangular height H is multiplied by each page break width ratio to calculate the scale and page number of the scroll bar side guide portion.
Then, in step 304, the page break width and coordinates on the scroll bar are stored based on the information calculated in step 303.

Next, the procedure of the process for searching the relative position of the scroll box in the document in the scroll bar control device will be described with reference to the flowchart shown in FIG. 4 and the image diagram shown in FIG. Scroll bar control device 10
5 acquires the current position coordinates from the data management device 103 in step 401. When the information indicating that the scroll box has been dragged is not notified as shown in step 402, display is performed from the current position in the display processing of step 407. As shown in the image 604, when the scroll box is dragged to the center of page 4 with the mouse using the guide part of the scroll bar side as a guide, in step 403, the image 60
The scroll box position coordinates (A, B) on the scroll bar shown in 7 are acquired. Further, in the process of calculating the page addition guide portion in step 404, the page division width on the scroll bar and the coordinates thereof stored in step 304 are acquired. In step 405, the image 60
The difference between the page break width coordinate shown in FIG. 3 and the scroll box position coordinate on the scroll bar shown in the image 606 is calculated until before the final page, and the coordinate having the smallest difference is used as a reference. In this example, it corresponds to the coordinates (a0, b3). Furthermore, the page break width (y4 /
The document relative position ratio is calculated by dividing the height B-b3 on the scroll bar obtained by the difference between the position coordinates of the scroll box shown in the image 607 and the coordinate of the page break width by Y) × H. In Step 406, Step 40
The document relative position ratio calculated in step 5 is multiplied by the document display height and converted into coordinates. As a result, the position of the scroll box on the scroll bar indicated on the document data can be recognized, and in step 407, display processing is performed from the coordinate position.

[0013]

As described above, according to the present invention, by installing the guide portion provided with the page number in which the page break width is variable according to the document amount of each page, the page desired by the user can be provided. Can be displayed easily, and the approximate document amount based on the display height of each page can be grasped by using the guide portion as a guide.
