[news.eclipse.platform.swt] Finding the right parent for a SWT Shell

["Mike Greenawalt" <mgreenawalt@xxxxxxxxxx>]

Hi -

I am developing some code in Eclipse. I want to open a window and display 
some data to the user. My problem is -- how do I determine the right parent 
for the window? Every SWT control needs a parent to be specified to its 
constructor, and I do not have a handle to the graphic environment of 
Eclipse at the point I want to display the data.

According to what I read about SWT, one cannot just create a new Display 
object -- there is supposed to only be one in effect at a time. So, I must 
use the existing Display as the parent of the Shell that I want to open.

Display.getCurrent() returns null, which means that my code is not running 
in the ui thread. That is probably true.

Display.getDefault() returns a Display object, but when trying to create a 
Shell with it as parent, the code throws a SWTException, Invalid thread 
access, which means the current thread is not the thread that created the 
object.

Any advice would be very much appreciated.
