How to draw focus?

[Peter Krueger <pkrueger appss de>]

Hello,
I have a GtkDrawingArea which shall get the keyboard focus when a user
clicks with the mouse over it. I want to draw a focus then as explained in
the GtkDrawingArea-docs with gtk_paint_focus(). But gtk_paint_focus() is
not documented. Can anyone explain me please how it shall be used and what
the meaning of the different parameters is?

Thanks...Peter
