Abstract

PURPOSE:To easily make a mixed display of a character string using plural kinds of character fonts of different character size in the same window. CONSTITUTION:When a user operates a function key 9-2 for a character size change command on a keyboard 9 for a window 21 in an input wait state, the number of columns and line width change determining means 8 determines the optimum number of columns and line width for a specified character size by referring to a character pitch and line width information control means 7 which holds optimum line widths and the number of columns per unit length by character sizes. Further, a font file control means 3 loads the contents of the character font file 1-2 of the specified character size in a buffer 10. A multiwindow control means 6 displays the character string in the window 21 with the determined number of columns and line width by using the character font of the specified size until change in character size is instructed again for the window 21.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a multi-window document display method in which character fonts of different sizes are used and character strings of different sizes are mixedly displayed in respective windows of a display screen.

[0002]

2. Description of the Related Art In a multi-window document display in which a plurality of windows are displayed on a display screen and a character string is displayed for each window, character strings are displayed using only one type of character font common to each window in the old days. Was,
Recently, as an improved version, it has been reported that character fonts of different sizes are used so that character strings of different sizes can be displayed in window units (for example, Japanese Patent Laid-Open No. 62-145283). reference). However, this technique cannot display a plurality of types of character strings having different sizes in a mixed manner in one window.

Therefore, as a further improvement of the above,
A document display method has been reported in which character strings of different sizes can be mixedly displayed in each window. This is because, for example, as seen in Japanese Patent Laid-Open No. 63-280296, the large headline character size, the small headline character size, and the main body character size are specified together with the specification of the document name in the document format setting. In editing, the main heading character, the sub heading character, and the body text are used properly so that character strings of a plurality of sizes can be displayed in one window.

[0004]

As described above, it has been possible to display character strings of various sizes in a mixed manner in a single window using character fonts of a plurality of sizes in the past. However, since it is necessary to specify the size of each character such as the large heading character, the small heading character, and the body character in the format setting, the user must input a character string using a window. If you want to use a character size that has not been formatted while you are there, you need to perform the formatting again and the work efficiency is significantly reduced.

The present invention has been made in view of such circumstances, and an object thereof is to execute a character size change command by pressing a predetermined key on the keyboard without the troublesome operation of formatting. Another object of the present invention is to provide a multi-window document display method in which a character font of a specified character size is used for display thereafter only by inputting.

[0006]

In order to achieve the above-mentioned object, the multi-window document display method of the present invention uses character fonts of a plurality of sizes to display different size characters in each window of the display screen. In the document display method of displaying columns in a mixed manner, when the user inputs a character size change command to the window, the number of columns and line width of the window suitable for the character font of the size specified by the command. After that, until a character size change command is input again to the window, a character font having the determined number of columns and line width and the size specified by the command is used to enter the same window. It displays a character string.

[0007]

Embodiments of the present invention will now be described in detail with reference to the drawings.

Referring to FIG. 1, an example of an information processing apparatus for carrying out the multi-window document display method of the present invention includes a plurality of character font files 1-1 to 1-n, a display 2, and a font file control means. 3, a terminal emulator 4, a font change notification means 5, and a multi-window management means 6 such as an X window system.
And the number of columns / line width information management means 7, the number of columns /
It is composed of a line width change determining means 8, a keyboard 9 and a character font buffer 10.

The character font files 1-1 to 1-n are files for storing alphabetic fonts and kanji fonts of different sizes for the same character code. The character font file 1-1 has a character size (1) ( For example, a character font of 16 x 16 dots)
The character font file 1-2 stores a character font of character size (2) (for example, 24 × 24 dots), ..., The character font file 1-n stores a character font of character size (n) (N × N dots), respectively. is doing.

The column number / line width information managing means 7 is designed to correspond to each character size (1) to (n) and is considered to be optimal when a character font of that size is used. The column number / line width change determining means 8 is means for holding information on the number, and when the font change notifying means 5 notifies the font change to a certain window through the terminal emulator 4, the changed font size is set. This is a means for determining the optimum number of columns and line width by referring to the column number / line width information managing means 7.

The keyboard 9 is an input device used by the user to input various commands and data. In this embodiment, the keyboard 9 has function keys 9-1 to 9-1 for inputting a character font change command. 9-n are provided. Each of the function keys 9-1 to 9-n has a one-to-one correspondence with a character font of each size, and when the function key 9-1 is operated, a command to change to a character font of character size (1) Is issued and the function key 9-2 is operated, the character size (2)
A command to change to the character font of is issued,
... When the function key 9-n is operated, a command for changing to a character font of character size (n) is issued.

The operation of this embodiment will be described below.

When the user gives an instruction to open a window, for example, by designating the character size (1) by operating the keyboard 9, the multi-window management means 6 will move the window in the horizontal direction as a part of preparation. The size L and the designated character size (1) are sent to the terminal emulator 4 through the font change notifying means 5 and requested to return the number of columns and the line width.

In response to this request, the terminal emulator 4 passes the window size L and the character size (1) to the column number / line width change determining means 8 to send the column number,
Requesting the return of the line width, the column number / line width change determining means 8 refers to the column number / line width information managing means 7 to determine the optimum line width for the designated character size (1), and The optimum number of columns is obtained by multiplying the window size L by the optimum number of columns per unit length for the designated character size (1), and the result is returned to the terminal emulator 4. The terminal emulator 4 notifies the multi-window management means 6 of the returned number of columns and line width.

On the other hand, the terminal emulator 4 passes the specified character size (1) to the font file control means 3 in parallel with the above processing, and requests the loading of the character font. In response to this, the font file control means 3 opens the character font file 1-1 of the designated character size (1) and the terminal window emulator 6 allows the multi-window management means 6 to refer to the character font in it. Load into buffer 10 via 4.

The multi-window management means 6 uses the number of columns, the line width and the character size (1) designated by the user notified from the terminal emulator 4 as control information of the document data of the window to be opened, for example, as shown in FIG. As indicated by reference numeral 101 of No. 2, it is set in the document data storage area 100 corresponding to the window. Then, the designated window is displayed on the screen of the display 2. In this case, it is assumed that the window 21 is displayed. The document data storage area 100 is provided in the multi-window management means 6, for example.

After that, when a character string is displayed on the window 21 by inputting a character from the keyboard 9 or the like,
The multi-window management means 6 uses the control information 101 shown in FIG.
In accordance with the above, the character font corresponding to the character code of the character size (1) to be displayed is read from the buffer 10, and the character string is displayed in the window 21 with the number of columns and line width designated by the control information 101 of FIG. To do.

Therefore, in the present example in which the character size (1) is specified and opened, the character size (1) is 16 × 16 size as shown in FIG. The character strings 201 and 202 are displayed with the width. The multi-window management means 6 displays the character codes of the displayed character strings 201 and 202 as 1 in FIG.
As indicated by 02, it is stored in the document data storage area 100 after the control information 101.

Now, the user who is creating a document in the window 21 sets the character size to be used thereafter to 24 × 2.
In order to change to 4 dots, when the window 21 is in the input waiting state, that is, when the prompt is returned, the function key 9 on the keyboard 9
When -2 is operated, a command to change to the character size (2) is issued.

When the command for changing to the character size (2) is issued, the multi-window managing means 6 sends the character size (2) and the window size L designated by the command through the font change notifying means 5 to the terminal emulator. 4 and request to return column number and line width.

In response to this request, the terminal emulator 4 passes the window size L and the character size (2) to the column number / line width change determining means 8 to send the number of columns,
Requesting the return of the line width, the column number / line width change determining unit 8 refers to the column number / line width information managing unit 7 to determine the optimum line width for the designated character size (2), and The optimum number of columns is obtained by multiplying the window size L by the optimum number of columns per unit length for the designated character size (2), and the result is returned to the terminal emulator 4. The terminal emulator 4 notifies the multi-window management means 6 of the returned number of columns and line width.

Further, in parallel with the above processing, the terminal emulator 4 passes the specified character size (2) to the font file control means 3 and requests loading of the character font. In response to this, the font file control means 3 closes the currently opened character font file 1-1, then opens the character font file 1-2 of the specified character size (2), and the characters in the character font file 1-2 are opened. The font is loaded into the buffer 10 via the terminal emulator 4 so that the multi-window management means 6 can refer to it.

The multi-window management means 6 uses the number of columns, the line width and the character size (2) designated by the user notified from the terminal emulator 4 as the control information of the document data used in the window 21 thereafter.
For example, it is set in the document data storage area 100 corresponding to the window as indicated by reference numeral 103 in FIG.

After that, when a character string is displayed in the window 21 by inputting a character from the keyboard 9 or the like,
The multi-window management means 6 uses the control information 103 shown in FIG.
In accordance with the above, the character font corresponding to the character code of the character size (2) to be displayed is read from the buffer 10, and the character string is displayed in the window 21 with the number of columns and line width designated by the control information 103 of FIG. To do.

Therefore, after the change to the character size (2) is designated, as shown in FIG. 3, the character size (2) is 24 × 24, and the number of columns and the line width determined above are used. , The character strings 203 to 205 are displayed. The multi-window management unit 6 stores the codes of the displayed character strings 203 to 205 in the document data storage area 100 after the control information 103 as shown at 104 in FIG.

After that, when the change of the character size is instructed again, the same operation as described above is performed, so that the character string is displayed in the changed character size. In FIGS. 2 and 3, since the change to the character size (1) is instructed again, the character string of the character size (1) is displayed in the window 21 and the document data storage area 100 corresponding to the window 21 is displayed. This shows that the control information 105 of the changed character size (1), the number of columns, and the line width and the character code string 106 of the displayed character string are stored.

The above operation is similarly performed for the other windows 22. Therefore, it is possible to display a character string having a plurality of character sizes for each window.

At the time of switching the active window, the multi-window management means 6 uses the document data storage area 10 corresponding to the newly activated window.
The latest character size is recognized from 0, and if there is no character font of that character size in the buffer 10, a request is sent to the terminal emulator 4 through the font change notifying means 5 to load the corresponding character font in the buffer 10.

The contents of the document data storage area 100 as shown in FIG. 2 are stored in an external storage device (not shown) when the window contents are stored, and are read from the external storage device and used when the window is displayed again. It

In the above embodiment, only the character fonts in one character font file are stored in the buffer 10. However, if the size of the buffer is large, the contents of plural kinds of character font files may be stored. Of course good things.

[0031]

As described above, according to the present invention,
When a character size change command is entered by pressing a specific key corresponding to the changed character font size while using a certain window, the character font to be used after that is changed. It is easy and quick to mix and display a character string using a plurality of types of character fonts having different character sizes.
