[news.eclipse.platform.swt] Re: Expanding Column Widths to fit table

[Guillaume Cauchon <guillaume.cauchon@xxxxxxxxxxxxxx>]

I did something similar with a ControlListenet, but on a single column 
and it is working pretty well...

I guess this is the best way to handle it because, if I'm not wring, the 
table size changes dynamically between the time it gets created 
(createPartControl) and the time that it gets displayed in the Eclipse 
IDe (plug-in or RCP)...

your_table.addControlListener(new ControlAdapter(){
	public void controlResized(ControlEvent event){
		if(your_table.getClientArea().width > 0)
			// Do whatever you want with the extra width
			// your_table.getClientArea().width
		}
	}
});
