How do I change the font of a GtkText widget?
There are a couple of ways of doing this. As GTK+ allows the appearance of applications to be changed at run time using resources you can use something like the following in the appropriate file: style “text” { font = “-adobe-helvetica-medium-r-normal–*-100-*-*-*-*-*-*” } Another way to do this is to load a font within your program, and then use this in the functions for adding text to the text widget.
