[java-gnome-hackers] Widget ref and unref

[Mark H. <mh...@ti...>]

hi,
  If a widget is removed from a container, it is destroyed unless there
has been a call to gtk_widget_ref(handle). To get the widget to be
destroyed, a call must be made to gtk_widget_unref(handle);

IMHO, this should not happen in Java - once you construct an object, it
should exist until the java reference to it is lost.=20
Therefore, I have added this code to the Widget class. The ref is made
in the initializeEventHanders method (All widgets should call this in
their constructors); and the unref is done in a finalize method, so it
will be done when java start garbage collecting the object.

I have not found any problems with this in the small amount of testing I
have done.=20

Let me know if there are any objection to this change.
