SWT Table - Checkbox / Highlight Listeners

I have a SWT Table with check boxes enable on the rows to allow TableItems to be selected. I currently have a listener on there

myTable.addListener(SWT.Selection, new Listener() {
        public void handleEvent(Event selectionEvent) {}});

This listener fires both when a check box for a row is checked and when a row is highlighted / selected, I haven't been able to find a way to separate these actions. Am I using the wrong listener or is there a way to do this?

Thanks for any help.
