AWT-EventQueue Block

I write a program to show the Swing buffer in JOGL,when i typed the Swing buffer in JOGL,the real Swing changed.
But the AWT-EventQueue Blocked,i do not know why,I use jvisualvm.exe to see the thread dump.

"AWT-EventQueue-0" prio=6 tid=0x04e30800 nid=0xcf0 waiting for monitor entry [0x068bf000]

how can i fix this problem.thanx.
sorry for my poor English.

Hi

What do you mean by "Swing buffer"?

What are you trying to do?

Edit.: Maybe you should not update any component directly in your listener(s), I would rather push changes on the event queue with SwingUtilities.invokeLater(Runnable runnable) or with a similar mechanism if this operation contains OpenGL code.

thanx,gouessej,with SwingUtilities.invokeLater(Runnable runnable)  i fixed it.

You're welcome but please, in the future, provide a small test case if you want to get some precise help.
