NewtCanvasAWT flicker on resize

I am experimenting with putting NewtCanvasAWT inside a JInternalFrame and using many of them in an application.  This seems to work, but I notice when I resize the JInternalFrame the NewtCanvasAWT flickers badly and the contents disappear until I stop dragging.

If I use GLCanvas the resize is smooth as long as I set -Dsun.awt.noerasebackground=true.  sun.awt.noerasebackground seems to make no difference for NewtCanvasAWT - I think this is because it calls disableBackgroundErase itself.

Is this a known problem/limitation with NewtCanvasAWT?

See my remarks/changes 86c164950b0a0d351fc8af3884187b10201b6237 in regards bug #439 ..,
hence setting this property should not be necessary anymore.

yes, after addNotify() which would work for Windows, not on X11, thanks to pointing this out,
added the same changes here as for GLCanavas, see above.

hope it was, wait until you see the commit, thx.

BTW .. please follow:
 http://jogamp.org/wiki/index.php/Jogl_FAQ#Bugreports_.26_Testing

ie at the very _least_ add the version dump to your email/bug-report,
so I know what you are actually refering to (source code, platform, ...).

Cheers, Sven

Thanks.  I see your commit aaa2b1df6ba9bd30f251.  Looks like the commit was about the same time as the last jogl-b237 build so I will try this on the next build.

wrong.

you can check ..

Just aggregated the latest autobuild 237
  http://jogamp.org/chuck/job/jogl/237/


you can check the changes 1st,
if it's not 'visible' there no panic, it doesn't mean to be complete, or correct.

Just pick up the revision number, ie 597007fc23fbf86e036629b6c6b157e0e0506715
and check via git if it's in there.

For the next rc2 today/tomorrow, I will provide a proper changelog.

Sorry, I didn't realize there was a public hudson server.

I picked up the 237 autobuild: test.log

Results:

1. GLCanvas does not flicker now even when sun.awt.noerasebackground is not set.  So it looks like 86c164950b0a0d351fc8af3884187b10201b6237 works.

2. NewtCanvasAWT still flickers badly on resize.  So it looks like aaa2b1df6ba9bd30f251ddada32ba0d56b12aa81 didn't quite work as expected.

I can provide code for my example program if it's helpful?

I am attaching code for my "NEWTTest" program that shows NewtCanvasAWT flickering when a JInternalFrame containing it is resized.

we have to see into that

sure, very much

and _PLEASE_ follow: http://jogamp.org/wiki/index.php/Jogl_FAQ#Bugreports_.26_Testing

These bugreporting requirements are no joke, they give us all the required information,
ie the test.log with OS, GPU, Java .. information.

It's ok to use email here, even though a bugzilla entry is much easier to track .. well.
But please produce at least this JoglVersion information.

Thank you very much.

Cheers, Sven

Ok, looks like flickering on JInternal Frame resize can be reproduced.

I added simple Frame/JFrame tests, which reproduce the same flickering on resize using NewtCanvasAWT.

Will see what I can do...

Thanks for your help Sven.

Regarding bug report information, I attached a test.log to this message in this thread: http://jogamp.762907.n3.nabble.com/NewtCanvasAWT-flicker-on-resize-tp1979434p1981497.html 

Maybe I am dumb and missing something - is there some more data you would like in bug reports?

no sorry, I missed you log file, since I don't see attachments right away
since I read them via emails ..

Fixed JOGL: f1b6d82acda9c88bfeb8d1913b4d101539c45391

The background erase bug was present in _all_ X11 NEWT windows :)

Now behavior is the same for Windows and X11, no erase.

Thank you, Sven

Thanks.  I downloaded jogl autobuild 239 and verified resizing looks better.
