Hi Ben,

I don't know how to solve but I've included the albireo newsgroup which
deals with Swing/SWT.

The problem looks like the Swing event loop is not working appropiately
hence no events are delivered to the Swing components.

Hi Ben,

I make use of SWT_AWT bridge successfully to bring panels from Swing
application into SWT/Eclipse. First thing, if it's possible use Albireo
since SWT_AWT has some bugs and issues and the workarounds could be tricky
depending on your requirements.

Try the following to see if it works:

Hold the composite object > parent in a global variable at your FtieView
class level. Then override the "setFocus" method of "ViewPart" and in this
createPartControl with the global parent object. This is not the best way
but if it works then we could try the workaround.

Thanks,
Rahul
