Re: painting over an widget

[Stefan Kost <kost imn htwk-leipzig de>]

I've further experiemnted with this. I am now overriding the expose event of the
widget (treeview) with my own method.
This gets correctly invoked and I just call the expose_event of parent and
afterward do a few gdk_draw_line calls.
No crash no warnings, but no lines neither.

It would be really nice if someone could help me or point me into the right
direction.
