Entering / Exiting FullscreenMode

Thierry · October 4, 2003, 8:22am

Hello everyone,

I would like to switch from fullscreenmode to windowed mode and windowed mode to fullscreen mode.

I have tried

Fullscreen to Windowed :

setFullScreenWindow(null);
setSize(800, 600);

but there i can’t use setUndecorated(false) because the window is displayable. Is there a way to make a JFrame not Dispayable without destroying it (i tried setVisible(false) didn’t work) ?

Windowed to FullScreen :

after using the setSize(800, 600) it seems that there is no way back to fullscreen.

Thanks for your help.

Don’t even bother trying; its bugged to hell.

With a good number of hacks its possible to get it almost working, however there is still 1 bug (a disposer crash in the GC) that is unworkroundable

I think the promise is ‘it will be fixed in Java1.5’. We can only hope :-/

“unworkaroundable” nice word

I hope it’ll be fixed in 1.5… “please restart” doesn’t really cut it :-/

you have to dispose() and pack() it again. Works, but sometimes has some flaws.

There is a Tutorial on suns site

howto switch to fullscreen and vice versa

also look here

http://javaalmanac.com/egs/java.awt/screen_FullWin.html

when switching back from fullscreen to windowed mode DO NOT SET DISPLAY MODE

use this

setFullScreenWindow(null)

and everything will be fine

Fullscreen to Windowed Mode switching is not perfect at the moment, but it works in my app without crashing, but i cant post any code here.

Also look for old posts from me here, we discussed this problem earlier

that example doesn’t deal with turning decoration on/off.

That is the root of all the problems.

MGodehardt · October 6, 2003, 2:38pm

the website is a good resource for beginners, maybe its helps him.

abuse i solved the decoration problem, switching is no problem.

So you’ve found a workaround for the Disposer crash?!

MGodehardt · October 7, 2003, 8:49am

Yes from Fullscreen to Windowed

simply call setFullscreen(null)

DO NOT change Display with setDisplayMode

In rare cases it crashs the app

I use one window ( not the 2 window workaround )

P.S.: I use same bitdepth in windowed and fullscreen ( 16bit )

My problem wasn’t to use setFullScreen(null).

It was after when I try to put decoration back with :

setUndecorated(false)

it throws an exception telling me that the window is displayable…

Thanks for the site anyway it answered others questions.

So Many bugs to fix, So little Time !

A displayable window cannot have its decoration changed.
Therefor you have to call dispose() on the window to release it from its native screen resources.
You can then change the decoration, and make the window visible again.
However, im 99.9% sure its still buggy and will cause a crash.
