Swing embedded in SWT JPo

  To: comp.lang.java.gui
I'm having problems when I embed an Swing component within an SWT
composite. Inside the Swing component I have a JTable that contains a
JPopupMenu. The popup menu comes up fine when I right mouse click and
go does correctly if I click anywhere inside the Swing component but
DOESN"T dissapear when I click on an SWT appear of the application.


Eclipse/SWT? I'm using the Eclipse 3.2.1 and the associated SWT 3.2.1.

Here's a simple block of code that can be used to reproduce the
problem. Am I doing something wrong? Or do I have to manually code
the popdown of the Swing JPopupMenu from the SWT thread?
