So to use C++ you can always either pass the object into the static function: class CFrame { static gboolean ReadData(CFrame* me); }; /* ... */ g_timeout_add_seconds(1,(GSourceFunc)CFrame::ReadData,frame); or I would prefer to leave the C++ alone and write a small wrapper frame_ReadData(CFrame* f) { return f->ReadData(); } /* ... */ g_timeout_add_seconds(1,(GSourceFunc)frame_ReadData,frame); _______________________________________________ gtk-list mailing list gtk-list@xxxxxxxxx http://mail.gnome.org/mailman/listinfo/gtk-list
