RE: [java-gnome-hackers] Constructor for org.gnu.gtk.ProgressBar

[Jeffrey M. <Jef...@Br...>]

I have added the constructor to ProgressBar.  The need to 
construct a widget from a native handle is prevalent through
the library.  Every method that returns a widget needs
this capability.  I don't like the fact that we have created
these public constructors but I haven't been able to think
of a better solution.
