Single click vs double click in mouseDown and mouseUp

[Alain Birtz]

For a double click mouseDown and mouseUp catch 2 event:
the first report clickCount value 1 and the second report value 2.
How to respond to a single click ?
If clickCount value is 1 the event can be either a single click or
the first event of a double click.

The answer for the double click is not the same as the one for the single click.
For the double click I need just give an answer when clickCount value is 2.
But how to answer to a single click event ?

If it's a single click, you won't get another click within the
doubleclick time interval. m.

Macintosh programs always execute the single click handler on the first
click of a double-click. It would make a program unresponsive to wait.
If you can't, you need to rethink your user interface.

HUman Interface Guidelines require that the behavior of a single click and the
behavior of the first click of a double click be exactly the same. If you are
trying to do something other than that, you are doing something wrong. If you
tell us what you are trying to accomplish, we will probably suggest a better
approach.
