RepeatButtonTrigger
A repeat button trigger. This trigger will create a button that reacts to a consistent touch. This means it will call the set action repeatedly as long as it is touched. The RepeatButtonTrigger can be combined with one or more of the ButtonStyle classes to create a fully functional button.

The delay, measured in ticks, between first activation and second activation.
See also:
getInterval
| int getInterval | ( | ) |
The interval between repeated activations, measured in ticks.
This is the number of ticks between the an activation beyond the first and the following activation.
Returns:
