Re: [platform-dev] How to be informed of root TreeItem addition?

[Thomas Singer <ts-swt@xxxxxxxxxxx>]

There are other places, too, where - compared with Swing - SWT lacks 
events, e.g. if a controls becomes disabled. We have solved this in our 
applications by hiding the control behind a facade and sending the 
events ourselves.
