Can anyone advise how I might produce the following effect:
I have a Composite, which has numerous child widgets, one of which is a
Table, another of which is a Button.
The Button is defined as the default button for the Composite, so that
pressing ENTER always triggers this Button.
I want to introduce an exception to this behaviour. Whenever the Table, or a
row within it, has the focus, I want to
do something else when ENTER is pressed (in particular, display more
information about the row currently selected).
But I can't find a way to intercept the ENTER key when the Table has the
focus. I tried adding a KeyListener to the Table, but the KeyListener is
never called when ENTER is pressed.
At the moment, the only thing I can think of is to add a FocusListener to
the Table, remove the Button as the default button when the Table receives
focus, and make it the default again when the Table loses Focus.
Is there a better way than this?

You can use the SWT.Traverse event. Modify this snippet to look for
SWT.TRAVERSE_RETURN and it should WORKFORYOU.
