[news.eclipse.platform.swt] Re: TraverseListener

["Veronika Irvine" <veronika_irvine@xxxxxxx>]

The arrow keys already select the next item in a table, you do not need to 
override the traversal behaviour to achieve this.  Instead of trying to do 
this in a Traverse listener why not do it in a Selection listener?

The reason you are seeing the old selection is because in the Traverse 
event, the operating system has not yet processed the arrow key event and 
has not yet assigned the new selection.
