Thanks. > I didn't tested it but here is the typo I think. be carefull to verify that when the destroy signal is called, the $window still exists. iirc the destrioy signal is called just before really destriying it, but not 100% sure.

This function croaks if not called in list context. so, basically, you want to do ($x, $y) = $gtkwindow->window->get_position; note, also, the important "->window" --- this accesses the GdkWindow owned by the GtkWidget. remember that the GdkWindow doesn't exist until the widget has been realize()d or show()n.

Specifically, Can't call method "get_position" on an undefined value at ./test.pl line 20. Any ideas? Thanks. -- Steve Fox http://k-lug.org Loading Comments...
