Hi folks, I've wrote a little custom widget (subclassing GtkBox) and now I'm wanting to use it with GtkBuilder, but when I try to load the .ui with GtkBuilder i get a error: Gtk-CRITICAL **: Error building template class 'MyCustomWindow' for an instance of type 'MyCustomWindow': Invalid object type `MyCustomWidget' So, after create my custom widget which are the required steps so GtkBuilder can create widget sucessfully ? Thanks. _______________________________________________ gtk-list mailing list gtk-list@xxxxxxxxx https://mail.gnome.org/mailman/listinfo/gtk-list
