Re: [Java-gnome-developer] StatusBar issue + 2 questions

[Fred B. <cha...@ma...>]

thanks :)

1) yup, I had noticed for the callbacks.. nifty thing. Didn't realize it
wouldn't get the whole thing :\

2) Doh me! I was just getWidget() on the window, then hide() it.. that's
better though.

3) I will read up more for the StatusBar.

ps: copying list.
