libglade's _new() function has a "root" parameter: http://developer.gnome.org/doc/API/libglade/gladexml.html#GLADE-XML-NEW
This is necessary because libglade otherwise instantiates all the items in the file. Does GtkBuilder instead only instantiate the objects when you actually use gtk_builder_get_object()? I also think that the memory management of the result of gtk_builder_get_object() should be made clearer. It was never very clear for glade_xml_get_widget(), but it's more complicated now that we can get objects as well as widgets. For widgets, I guess that it's like this: 1. For child widgets, such as GtkButton, they belong to their parent containers and will be destroyed by them when the containers are destroyed, so you don't need to call g_object_unref() or gtk_widget_destroy(). 2. For top-level windows, such as GtkWindow, they should be destroyed with gtk_widget_destroy() when you are finished with them. But for objects, I guess that: 3. For objects, such as GtkTreeModel, g_object_unref() should be called. This would require that a reference is given when glade_xml_get_widget() is called a second time, as well as the first time. This would be inconsistent with other GTK+ API, but it does not seem sensible to expect the application code to know when the result has just been instantiated rather than simply returned again. And it would be nice to know whether the objects are reference/owned at all by the GtkBuilder instance? For instance, should we expect the widgets to be destroyed when the GtkBuilder instance is unreferenced? I guess not, but it should be stated. -- Murray Cumming [EMAIL PROTECTED] www.murrayc.com www.openismus.com _______________________________________________ gtk-devel-list mailing list gtk-devel-list@gnome.org http://mail.gnome.org/mailman/listinfo/gtk-devel-list
