Description

get_fontget_fontget_fontGetFontGetFont queries the name of the font used in the output window. The font is used by the operators write_stringwrite_stringwrite_stringWriteStringWriteString, read_stringread_stringread_stringReadStringReadString etc. The font is set by the operator set_fontset_fontset_fontSetFontSetFont. Text windows as well as windows for image display use fonts. Both types of windows have a default font that can be modified with set_system('default_font',Fontname)set_system("default_font",Fontname)set_system("default_font",Fontname)SetSystem("default_font",Fontname)SetSystem("default_font",Fontname) prior to opening the window.
