Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a character string display method for automatically adjusting the size of character fonts displayed within a window in a window system supporting multi-sized fonts.

0002

[Prior Art] In a conventional window system,
The size of the characters displayed within the window on the display screen was fixed, and the amount of characters that could be seen through the window depended on the size of the window. Therefore, when the amount of characters is larger than the window, it is necessary to scroll the text within the window or increase the size of the window. but,
The method of scrolling the text has the disadvantage that only a portion of the content is displayed, making it difficult to grasp the overall content. Furthermore, when a large number of windows are open on the display screen, it may not be possible to enlarge the window to a size that can display all the contents, and the text must be scrolled. On the other hand, in a window system that supports multi-size fonts, the size of the character font within the window can be changed arbitrarily.

0003

[Problem to be Solved by the Invention] However, in conventional window systems that support multi-size fonts, when changing the size of character fonts in a window, the user has to change the character width, height, etc. Since it is necessary to give instructions to the text, there is a problem in that operations become complicated when referring to multiple texts.

An object of the present invention is to provide a character string display method in which the system automatically adjusts the size of character fonts displayed in a window to reduce the burden on the user.

[0005]

[Means for Solving the Problems] In order to solve the above problems, in the character string display method according to the present invention, the area necessary for displaying text consisting of character strings is ), the text font size is increased until the area required to display the text is less than or equal to the window on the display screen, or until the size of the text font is the smallest that can be displayed on the display screen. I'm trying to reduce the size. When determining the size of the text font, for example, find the maximum width and height of the area in the window that can display text, and make sure that the maximum width of the text is smaller than the width of the area that can display the string ( or equal), and then reduce the text font until all lines of text are less than (or equal to) the height of the area in which the string can be displayed. If the entire text cannot be displayed even if the text font is made the smallest, the text font size is determined to be the size obtained at that time, and only the portion of the text that fits within the window is displayed.

[0006]

[Operation] According to the above character string display method, the size of the character font is automatically adjusted based on the area required to display the text and the size of the displayed text.
Text can always be displayed in a font size that corresponds to the window size. Therefore, it is no longer necessary to specify the width, height, etc. in order to obtain characters that match the size of the window, and the operability of the system can be further improved. Furthermore, even if the window size is changed, the entire screen can be displayed as much as possible.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the character string display method according to the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the functional configuration of a computer system to which a character string display method according to the present invention is applied. In FIG. 1, an application 1 such as an editor or a file displays characters on a display screen via a window/font management system 2. The window font management system 2 is
While exchanging information with the window system 3, an appropriate character font size is determined, and the characters are output to the screen display device 5 through the operating system 4.

FIG. 2 is a block diagram showing a specific circuit configuration of the above-mentioned computer system. This computer system includes a CRT 11 that is a screen display device that displays multiple windows on a display screen, a CRT driver 12 that controls the display on the CRT 11, and a keyboard 13 that inputs commands, character strings, numerical values, etc. , the CRT 11
A mouse 14 for inputting instructions from the user to the window displayed above, a keyboard/mouse driver 15 for outputting various data by the user's operation of the keyboard 13, and various data and programs are stored. It is composed of a disk device 16, a disk device driver 17 that controls data input/output from the disk device 16, a memory device 18, and a CPU (central processing unit) 19.

The memory device 18 stores programs for executing the window/font management system 2, the window system 3, and the operating system, application programs, and characters and numbers input from the keyboard 13 and mouse 14. Data is stored. The memory device 18 also contains information necessary for the window/font management system 2 (width and height values of the area where text can be displayed in the window, text width and height, window width and height, (character font size, etc.) are stored in a predetermined storage area.

The CPU 19 is a circuit that controls the entire system and performs arithmetic processing on predetermined data based on various instructions. include. Among these, in window/font management system 2, if the area required to display text is larger than the window on the display screen, , or until it becomes the smallest character that can be displayed on the display screen, and displays only the portion of the text that will fit in the window.

[0011] When determining the size of the character font,
First, reduce the text font until the width of the text is less than the width of the available area of the window, then reduce the text font until all lines of text can be displayed within the available area of the window. Make smaller. If all of the text cannot be displayed even when the font is set to the smallest size, the text font size is determined at that time, and the text is written in the window using that text font.

Next, the processing procedure of the window/font management system 2 when determining the size of a character font will be explained with reference to the flowcharts of FIGS. 3 and 4.

In the flowchart of FIG. 3, the window/font management system 2 determines the width and height of the currently displayed window (step 101), and further, based on the information on the width and height of the window, The maximum width and height of the area in the window where text can be displayed is determined (step 102). Then, set the maximum width and height of the area that can display text in the window.
Let maxX←width of the area and maxY←height of the area, respectively (step 103). Next, the value of the widest line in the text is determined, and the value is set as x←maximum width line (step 104). Then, it is determined whether the x is greater than maxX (step 105), and if x is greater than maxX, it is determined whether there is a font that is one rank smaller (step 106). If there is no font that is one rank smaller, the process ends; if there is a font, the font is made one rank smaller (step 107).
), return to step 104.

Next, in the flowchart of FIG. 4, if x is not larger than maxX in step 105, the height of the entire text is determined and set as y←(font height + margin) x number of lines (step 108). Then, it is determined whether the above y is larger than maxY (
step 109), if y is greater than maxY, 1
It is determined whether there is a font with a lower rank (step 110). Here, if there is no font that is one rank smaller, the process ends, and if there is a font, the font is made one rank smaller (step 111), and step 10
Return to 8. Furthermore, if y is not larger than maxY in step 109, the process ends at that point.

FIG. 5 shows an example of a display using a conventional window system. In the conventional method, when the size of the window 23 is small compared to the amount of text 22 on the display screen 21, it is not possible to display all the contents. Therefore, in order to check the entire contents, either increase the size of the window or use the text 2
2 had to be scrolled up, down, left and right. on the other hand,
FIG. 6 shows an example of display by the window/font management system of the above embodiment. In FIG. 6, since a character font of an appropriate size is determined based on the amount of text 22, it is possible to display the entire content without cutting off the edges. Furthermore, even if the window size is changed and the character font cannot be displayed even if the text is set to the smallest size, it is possible to display as much of the text as possible.

In the flowcharts of FIGS. 3 and 4 described above, the width of the window is first focused, but this may be set as an option, and the height may be focused first. For example, if the width is extremely wide compared to the height of the text, if you focus on the width first, the font may become too small and there is a possibility that there will be a lot of white space in the vertical direction. Therefore, depending on the text to be displayed, it may be possible to select whether to emphasize either the height or the width. In this case, the user may be able to select it manually, or the system may select it automatically. Also, if the size of the text varies (for example, if one line is extremely long in horizontal writing), instead of taking the maximum height or width, calculate the average value and use it as the height or width of the text. May be applied as width.

Furthermore, in the flowcharts of FIGS. 3 and 4, the font is made smaller until all directions (width or height) that were noticed earlier can be displayed, but a certain condition is set and the condition is If satisfied, the font size may be determined at that point. For example, if you pay attention to the width first, if you reduce the size of the font to a certain point and the vertical direction is all (or half) displayed, even if the horizontal direction cannot be displayed completely, the font Make sure to write the characters in the correct size. Note that this process may also be automatically selected by the system.

Although the window/font management system 2 is incorporated into the system in FIG. 1, it may be incorporated into the application as a window/font management routine 6, as shown in FIG. Note that in FIG. 7, the same parts as in FIG. 1 are represented by the same symbols.

[0019]

[Effects of the Invention] As explained above, in the character string display method according to the present invention, when the area required to display text is larger than the window on the display screen, the area is at least as large as the window on the display screen. The size of the character font is reduced until it is equal to the size of the window, or until it becomes the smallest character that can be displayed on the display screen, so the width and height etc. This eliminates the need to specify, which greatly reduces the burden on the user.
