[news.eclipse.platform.swt] How to make a popup shell close when mouse c

[Hongying Zhang <hongying.zhang@xxxxxxx>]

Hello,
I need create a Popup Shell that will be popuped up when mouse click a 
control, and this popup shell has to be resizable with some other 
feature; this popup shell also need have a behavior that when the mouse 
clicked outside popup Shell, this popup shell will close (just like menu 
behavior ). Since I cannot subclass SWT Menu widget, so I created my own 
Popup shell class.

Now, I have problem to close it when mouse clicked somewhere outside the 
popup shell. I tried to let the shell listen to mouse up event, but that 
won'y work. Can someone please let me know what should I do to make this 
popup shell close when mouse clicked outside the Shell.

Thanks,
Hongying
