AS3 Double Click

The double click event introduced in AS3 (MouseEvent.DOUBLE_CLICK) will be working only if the button property "doubleClickEnabled" is set to true explicitly. If this property is not set the double click event will not be triggered.

customButton.doubleClickEnabled = true;
customButton.addEventListener(MouseEvent.DOUBLE_CLICK,onThumbClick,false ,0,true);

function onThumbClick(event:MouseEvent) {
trace(event.currentTarget);
}
