Signature

Description

set_fontset_fontSetFontSetFontset_font sets the font FontFontFontfontfont for the output window WindowHandleWindowHandleWindowHandlewindowHandlewindow_handle. All subsequent text outputs (e.g., with the operators disp_textdisp_textDispTextDispTextdisp_text, write_stringwrite_stringWriteStringWriteStringwrite_string or read_stringread_stringReadStringReadStringread_string) will now use the new font instead of the default font (see set_system('default_font',Font)set_system("default_font",Font)SetSystem("default_font",Font)SetSystem("default_font",Font)set_system("default_font",Font)). All available fonts can be queried with query_fontquery_fontQueryFontQueryFontquery_font.

The syntax for the specification of FontFontFontfontfont is the following:

     FONTNAME[-STYLE]-FONT_SIZE.

• Normal,

• Bold,

• BoldItalic, or

• Italic.

The FONT_SIZE is measured in pixels.

An example of a valid string for FontFontFontfontfont would be

'Courier-Bold-14'.

Attention

For different machines the available fonts may differ a lot. Therefore it is suggested to use the operator query_fontquery_fontQueryFontQueryFontquery_font or the procedure set_display_font.
