Hello, everyone!

I have jogl-2.2.4 on my system and I'm trying to use NewtCanvasAWT with Swing components. For my program I need hotkeys. In the example below pressed keys do not trigger action if focus is inside NewtCanvasAWT component - i.e. if I click somewhere in the window (not in NewtCanvasAWT) and then press key 'w' I will see my message "!!!!!!!!", but when I click mouse on NewtCanvasAWT and then press key 'w' I don't see anything.

Could you please help me this problem? How to trigger actions when the focus is inside NewtCanvasAWT?
