Hi !
I’m trying to use JOGL with QtJambi. I’m using code I found in tutorials (some of them are very old) and forums but nothing is displayed. The QGLWidget initialization prevents the window to be displayed.
I have no error in the console. The program is running, but there is no window.
Is there something I’m doing wrong ?
Here is my code.

I updated the jogamp .jar today and all my other programs using JOGL with swing work well.
Thank you in advance.
