Warning gtk_toolbar_append_element has been deprecated since version 2.4 and should not be used in newly-written code. Use gtk_toolbar_insert() instead. Adds a new element to the end of a toolbar. If type == GTK_TOOLBAR_CHILD_WIDGET, widget is used as the new element. If type == GTK_TOOLBAR_CHILD_RADIOBUTTON, widget is used to determine the radio group for the new element. In all other cases, widget must be NULL. callback must be a pointer to a function taking a GtkWidget and a gpointer as arguments. Use G_CALLBACK() to cast the function to GCallback.
