| Package | feathers.utils.touch |
| Class | public class LongPress |
| Inheritance | LongPress  Object |
| Product Version : | Feathers 2.3.0 |
FeathersEventType.LONG_PRESS from the target when
the target is long-pressed. Conveniently handles all
TouchEvent listeners automatically. Useful for custom item
renderers that should dispatch a long press event.
In the following example, a custom item renderer will dispatch a long press event when tapped:
public class CustomItemRenderer extends LayoutGroupListItemRenderer
{
public function CustomItemRenderer()
{
super();
this._longPress = new LongPress(this);
}
private var _longPress:LongPress;
}Note: When combined with TapToSelect or
TapToTrigger, the LongPress instance should be
created first because it needs a higher priority for the
TouchEvent.TOUCH event so that it can disable the other
events.

customHitTest:Function
In addition to a normal call to hitTest(), a custom
function may impose additional rules that determine if the target
should be long pressed. Called on TouchPhase.BEGAN.
The function must have the following signature:
function(localPosition:Point):Boolean;
The function should return true if the target should
be long pressed, and false if it should not be
long pressed.

longPressDuration:NumberThe duration, in seconds, of a long press.
The following example changes the long press duration to one full second:
longPress.longPressDuration = 1.0;
The default value is 0.5.
