* A demo that combines the techniques of ClickVersusDoubleClickUsingReleased
|
|
* and ClickVersusDoubleClickUsingSuppression by using both event types to
|
|
* trigger a "Clicked". I think this is the best of both worlds. If someone does
|
|
* a simple Press/Release, the Release gets triggered. If someone does a quick
|
|
* click, then a Click gets triggers (after a delay to wait for the potential
|
|
* DoubleClick).
