Exiting Fullscreen in TestGearsES2NewtCanvasAWT.java

Hello,

when exiting fullscreen in TestGearsES2NewtCanvasAWT.java it seems the reshape doesn't happen as one would expect. While the viewport is cut down to the lower resolution, it seems the renderer is still in the full screen resolution. As a result, only the red wheel is partially visible, expanded as it was on fullscreen.

Is this normal? I would guess it's based on the two threads (entering/exiting) fullscreen and the GL thread are not in synch. Any idea how one would go about this issue?

Hi

When exiting the full screen mode, the latest resolution in windowed mode is used, not the resolution in full screen mode. This is the expected behaviour. If you want to change that, modify the resolution before entering the full screen mode or just after exiting it.

Hey,

thanks for your answer. It seems from your description that my behavior is different. Have a look at this screenshot[0]. Here it looks like after exiting fullscreen, the gears are still in 1920x1200 resolution. I'm on Debian btw.

Actually, the size depends on the mode, not the resolution, my previous comment was a bit wrong. Anyway, you can modify this behaviour.

Isn't the expected behavior that it returns to windowed mode resolution? I'm not quite sure where to implement the change. I tried setting the viewport in reshape() which did not change anything. Do I have to implement displayChanged()?

Edit: I tried saving the resolution before going into fullscreen inside the keylistener that listens for pressing f. After switching out, I check if we are still in fullscreen, if not, I do glWindow.setSize() with the previously saved values. I get the following console output:

01. [set fullscreen  pre]: 0/0 1920x1200, f true, a false, [ l 0, r 0 - t 0, b 0 - 0x0]
02. window resized: 0/0 640x480
03. window resized: 0/0 640x480
04. Back out of fullscreen. Set: 640, 480

07. [set fullscreen post]: 0/0 640x480, f false, a false, [ l 0, r 0 - t 0, b 0 - 0x0]

11. QUIT Window Thread[main-Display-.x11_:0-1-EDT-2,6,main]

As you can see, in the first line, we are in fullscreen, we exit and the window is resized to 640x480 (line 02&03).
I added the 'Back out of fullscreen' message (04), after which I call glWindow.setSize().
We see that the thread issues a reshape to 640x480 (05).
However in line 08 and 09 it is once again reshaped to 1920x1200.

I don't understand where and why 08 and 09 happen.

I filed a bug report for this: https://jogamp.org/bugzilla/show_bug.cgi?id=836
Please see the JUnit test I included.

I've ran the JUnit test on several Debian machines and it fails on all of them. Is this not an issue for anyone else?

I'll try the unit test this weekend on an Mac OSX 10.8 and see if it behaves correctly there. Currently my Debian machine is headless and stashed in a closet :-)

I don't use AWT.

Thank you, I will have a look at .. but it may take a while.

I rewrote the unit test somewhat to be runnable as a stand alone JUNit test (hope I didn't break anything but I only changed the glWindow.addGLEventListener(this))

Anyhow, I ran it on my OSX 10.8 machine (using 2.0.2 JAR files + JDK 1.7_u40). The test starts fine in windowed mode, then switching to fullscreen. It looks like the resize works when switching back to windowed mode from fullscreen. The window appears but then the test crashes in native code after less than a second.
I added the crash report as a comment on bug 836. Let me know if I should file a separate bug report

Thanks, issue was resolved.
