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

["Carolyn MacLeod" <Carolyn_MacLeod@xxxxxxxxxx>]

Note that you can use the x and y coordinates in the event if you like - 
it's just that you have to map them to display coordinates before popping up 
your shell.
For example, in Snippet233 that Stuart pointed you to (under "Shell" on the 
http://www.eclipse.org/swt/snippets/ page), you can also change the line 
that uses the point using getCursorLocation() to the following:

 Point pt = display.map(shell, null, new Point(e.x, e.y));

which maps e.x and e.y to Display coordinates.

Hope this also helps,
Carolyn
