sure: 

  (GObject *) widget

The macro G_OBJECT (widget) does not create a GObject from the
GtkWidget, a GtkWidget is a GObject. G_OBJECT() is just a
type-checking cast which can be replaced by a simple cast.

Your question would have better been asked on gtk-list or
gtk-app-devel-list since gtk-devel-list is about the development
of GTK+, not developing with GTK+.


Salut, Sven
