Thanks a lot for your help. I'm new to libglademm and it's been a few years since I used gtkmm. I solved the problem using a "creation function" (an extern "C" wrapper around my constructor, looks somehow ugly in a C++ program). Now on_realize() is called. I've posted a .tar.gz of a working program on the list. on_realize(), on_configure_event(), on_expose_event() are called correctly. The visible attribute is enabled in glade. There's a small working sample program to the list in my "gtkglextmm with libglade example - source attached" posting. Philipp P.S.: I currently have a problem with on_button_pres_event() not being called, if I don't find a solution I'll post on the list soon. _______________________________________________ gtkmm-list mailing list [email protected] http://mail.gnome.org/mailman/listinfo/gtkmm-list
