Seems pretty simple to me:
click:
MouseDown
MouseUp
not a click:
MouseDown
MouseDoubleClick
MouseUp

We handle this case for you in the SelectEditPartTracker. The only way to
handle it is to do what the windows desktop does. You have to create a timer
and look for the double-click event before the timer goes off. Unfortunately
you'll have to guess how long the timer should be since the double-click
threshold is not exposed through SWT.
