get_fontget_fontGetFontGetFontGetFontget_font queries the name of the font used in the
output window WindowHandleWindowHandleWindowHandleWindowHandlewindowHandlewindow_handle. The font is used by the operators
write_stringwrite_stringWriteStringWriteStringWriteStringwrite_string, read_stringread_stringReadStringReadStringReadStringread_string etc. The font is
set by the operator set_fontset_fontSetFontSetFontSetFontset_font. 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',Font)set_system("default_font",Font)SetSystem("default_font",Font)SetSystem("default_font",Font)SetSystem("default_font",Font)set_system("default_font",Font) prior to opening
the window. A list of all available fonts can be obtained using
query_fontquery_fontQueryFontQueryFontQueryFontquery_font.
