[news.eclipse.platform.swt] Composite update problem

["Marco Kohns" <mek@xxxxxxxxxxxx>]

Hello everybody,

i have a composite_mother and inside that a toolbar (with two toolitems) and 
another composite_child. When I press one of the toolitems, the 
composite_child changes its content. But I can only see that when I resize 
the window of the application.

What I've tried so far:

 composite_child.layout()
composite_mother.layout()
shell.layout
shell.update
composite_mother.pack()
composite_child.pack()

But without success...

Thanks for any help!
