[news.eclipse.platform.swt] Updating a widget from a background running

[Xavier <xavier.mehaut@xxxxxxx>]

Hello,
I would like to update for instance a text field in a view from a Thread 
running in background. Unfortunately, this throws an error because we 
try to update the field from another thread wich is not a "graphical" 
thread.
Is there a simple means to do that properly?
regards
Xavier
