How to dispatch a triggered event from a custom item renderer

A custom item renderer should dispatch Event.TRIGGERED when it is tapped or clicked, similar to a Button.

Using the TapToTrigger class, it's easy to dispatch Event.TRIGGERED on tap or click:

public class CustomItemRenderer extends LayoutGroupListItemRenderer
{
    public function CustomItemRenderer()
    {
        super();
        this._trigger = new TapToTrigger(this);
    }

    private var _trigger:TapToTrigger;
}

That's it! The TouchEvent.TOUCH listeners will be added automatically, and your item renderer will dispatch Event.TRIGGERED like a button.

You should also learn how to use TapToSelect to change isSelected and dispatch Event.CHANGE when tapped or clicked.
