[news.eclipse.platform.swt] Re: How to set Canvas focusable (with keyboa

[Alexander Kitaev <alex@xxxxxxxxx>]

Finally after I understood what the problem was - to make Canvas 
subclass focusable with the traversion keys one have to hook at least 
one of SWT.keyDown or SWT.keyUp events, otherwise widget will be skipped 
when traversing by tab order.
