Global Key Listener [message #1027045]

Hello,

I'd like to assign a 'global' key listener to my custom eclipse preference page. My page contains some composites with 3 tables as childs. So at the moment I assigned the listener to my parent composite inside the createContents method of the preference page.

parent.gerShell().getDisplay().addFilter(SWT.KeyDown, keyDownListener);

This works fine until I make any selections inside the table. If the table is "active" the key listener is not listening anymore. Are there any other places I have to assign the listener to make it work global? I tried to assign it to the tableViewer control and table but this is not working.

Any ideas?

Greetings,
Sascha

ok, I've tried to add a listener to every table in my main composite.

	table1.getTable().addKeyListener(tableKeyListener);
	table2.getTable().addKeyListener(tableKeyListener);
	table3.getTable().addKeyListener(tableKeyListener);

As soon as I make a selection inside one of the tables the listener is not triggered anymore. It seems like loosing the main window focus (this happens if you select an item in the table) turns off the listener.
