i have a Shell that has a MouseListener attached to it... double
clicking the mouse in the shell invokes all three methods in the
MouseListener (which should be the case) but i want to determine if the
user double clicks or single click my shell... how do i distinguish
between a single click and a double click? is there a SWT counterpart of
Swing's MouseEvent.getClickCount() ?

However, the reason you can't distinguish is by definition single-click
means select, and then double-click means do default action based upon
the selection done in the first click. So they are meant to be
associated with each other. So the first click is supposed to selection,
no matter whether it came from a single click or a double click.
