JOGL and swing

I was trying to make a menu and then when I click the menu, I add the 3d canvas to the frame.

However, it doesn't work as I expected and it freezes there.

Here is the codes. The codes only work when I comment the final GLProfile glp = GLProfile.getDefault(); in the public void actionPerformed(ActionEvent e) function and uncomment the global one.

What's the difference there? Thanks.

By the way, I'm using the rc11 with JAVA 7 in Windows 7.

Hi

At first, please use the very latest build of JOGL 2 instead of the RC 11.

Secondly, you can get the GLProfile once for all earlier and not in actionPerformed().

Yep, the latest build works.

Thanks.

You're welcome, thank you for the feedback. I know that some developers are lazy but using obsolete builds is a waste of build. When the developers use very recent builds, they can detect regressions and report them, it is very helpful to fix them. I advise you to use at least the latest release candidate.

agree with that

Hi, gouessej

I'm using the release version 2.1.2 now.

And I'm wondering which version of JDK of the 2.1.2 is compiled with.

I didn't find any information about that information from the download package.

Do you know anything about it?

Thanks.

Please use the latest build of JOGL 2.1.3. Java 1.7 (update 45?) is used but it is still compatible with Java 1.6.

I have this question because when I'm using JOGL 2.1.2 with Java 1.7 (update 9),
it doesn't work well especially for the 64bits version.

And indeed with a higher Java 1.7 version like update 45, it works great.

So I think it would be better to include the Java compiler information in the jogamp-all-platforms package.

Please be more accurate, you're very vague. I used JOGL 2.x with OpenJDK 1.6 for months without trouble.

The example I'm using is the one I posted in my first post in this thread.

For JOGL 2.1.2, originally I'm using Java 1.7 (update 9) for the example, it is not stable and it sometime freezes after I click the new button and move my mouse over the frame title (or the position of the minimize/maximize button), more easy to reproduce in 64bits version.

After I updated to the latest Java 1.7 (update 45), everything works great.

Since I used the jogamp-all-platforms.7z downloaded from http://jogamp.org/deployment/
so I asked, for the JOGL 2.1.2, which version of JDK (update number) you guys are using to compile the JOGL libs to generate the jogamp-all-platforms.7z.

I suggest that it's better the information can be added to the package.

Thanks.

So bugs in the AWT/Swing implementation got fixed - great.

We build against a JRE RT of Java 1.6 targeting Java6.

See:
<http://jogamp.org/git/?p=gluegen.git;a=blob;f=make/jogamp-env.xml;h=fbf7f5679addd5ffee519e32a115d07345aab6c2;hb=HEAD>

It is orthogonal against which java version we build regarding
bugs occurring in a AWT/Swing implementation.
