<AWT Dev> Why does JFrame.setSize conflict with JFrame.setExtendedState?

Hi Oleg,

Thanks a lot for anwering.

Yes that was also my assumption.
The idea behind the code was that the window should show up maximized,
and when the user clicks on the maximize icon/button in the
window-title-bar, the JFrame should resize to the 800x600 size.

I tested with 6u10b13, but saw the same behaviour till back to
JDK-1.4.2, and also with 6u10 and MAWT.

I see the same behaviour as you. Usually it opens up with 800x600 and
maximizes, but sometimes it simply stays at 800x600.
Could it be that there's a race somewhere, and the window-manager gets
the command to maximize before the command to set the window to
800x600?

Sleeping 100ms between resizing and maximizing it works reliable:
setVisible(true);
setSize(800, 600);
sleep(100);
setExtendedState(MAXIMIZED_BOTH);

With JDK7b19 I somtimes see the window maximized only horizontal (1280
on my laptop) but only 50px high, which is of course even worse,
however I never see it 800x600.

Any ideas where this could come from? Adding XSync() to
XBaseWindow.setBounds does not help ;)


Thanks a lot, lg Clemens

PS: this has really low priority for me, I just found it and thought
its worth reporting. I hope I don't steal any time away ...
