[news.eclipse.platform.swt] How to let Popup Shell show up at the given

[Hongying Zhang <hongying.zhang@xxxxxxx>]

Hello,

I need create a pupup shell that when a widget is clicked that popup 
shell can open at the Mouse location. I tried to call setLocation, but 
it doesn't work. the popup shell always show up at the top right corner 
at my desktop.

Can someone please what I should change to let the popup shell show up 
in the correct location? Please see the snippet to reproduce the problem.

Thanks,
Hongying Zhang
