Re: [Java-gnome-developer] parent missing from GtkWidget

[Julian F. <jul...@be...>]

Argh... forget this one... I originally had (GtkWidget parent) but then had=
 to change it in code to use GtkContainer.  I then changed the defs file to=
 use GtkContainer but didn't try it before submitting the patch.. of course=
 I find it won't build because GtkContainer isn't defined yet at this=
 point... 

Of course, this doesn't solve the problem that it doesn't work without=
 being a GtkContainer... in fact, it really needs to return a GtkContainer=
 but create an object that is actually of the correct subclass of=
 GtkContainer.  Shouldn't this always be the case?  Shouldn't all the=
 methods create objects of the appropriate type and just return them as a=
 superclass where necessary?
