Hi all,
I have a class that derives from Glib::Object that should implement
Gtk::Orientable. I thought it would be sufficient to just do:
class MyClass : public MyParentClass, ::Gtk::Orientable {
public:
MyClass() : Glib::ObjectBase(“MyClass"), MyParentClass(),
Gtk::Orientable() {}
};
Even though this compiles without problems, I do get into trouble at runtime
with errors like:
(test1:35777): GLib-GObject-WARNING **: attempting to add an interface
(GtkOrientable) to class (gtkmm__CustomObject_MyClass) after class_init
(test1:35777): Gtk-CRITICAL **: gtk_orientable_get_orientation: assertion
'GTK_IS_ORIENTABLE (orientable)' failed
(test1:35777): Gtk-CRITICAL **: gtk_orientable_get_orientation: assertion
'GTK_IS_ORIENTABLE (orientable)' failed
I have tried changing the order of the parent constructors but that doesn’t
seem to make a difference.
I would be very grateful for any help!
Thanks in advance and best regards,
Tom
