get_font

Herror ::get_font ( const HTuple &WindowHandle, char *Font ) HTuple HWindow::GetFont ( ) const

Get the current font.

::get_font queries the name of the font used in the output window. The font is used by the operators ::write_string, ::read_string etc. The font is set by the operator ::set_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',Fontname) prior to opening the window. A list of all available fonts can be obtained using ::query_font.

Parameters

`WindowHandle` (input_control)	window `->` HTuple.long
Window identifier.

`Font` (output_control)	string `->` char *
Name of the current font.

T_write_string(TupleWindowHandle,String) ;
new_line(WindowHandle) ;
set_font(WindowHandle,CurrentFont) ;
