Dear John,
thanks for the code snipped,
it was really helpful. I copied
it to my small sample windows application
and the ref_window "pointer" is null?:
12 window.set_default_size(800,600);
(gdb) n
16 Glib::RefPtr <Gdk::Window> ref_window;
(gdb) n
18 ref_window = window.get_window();
(gdb) n
20 Gdk::Cursor m_Cursor (Gdk::WATCH);
(gdb) p ref_window
$2 = {pCppObject_ = 0x0}
(gdb)
... and my application dies.
I guess I do need to do more, or I do something terribly wrong :-)
I moved the code into my window constructor but it did not help either.
Any idea ?
Karl
