public trackAsMenu : Boolean
A Boolean value that indicates whether other buttons or movie clips can receive a release event from a mouse or stylus. If you drag a stylus or mouse across a movie clip and then release it on a second movie clip, the onRelease event is registered for the second movie clip. This allows you to create menus for the second movie clip. You can set the trackAsMenu property on any button or movie clip object. If you have not defined the trackAsMenu property, the default behavior is false.
You can change the trackAsMenu property at any time; the modified movie clip immediately takes on the new behavior.
Note: This property is supported in Flash Lite only if System.capabilities.hasMouse is true or System.capabilities.hasStylus is true.
The following example sets the trackAsMenu property for three movie clips on the Stage. Click a movie clip and release the mouse button on a second movie clip to see which instance receives the event.
myMC1_mc.trackAsMenu = true;
myMC2_mc.trackAsMenu = true;
myMC3_mc.trackAsMenu = false;
myMC1_mc.onRelease = clickMC;
myMC2_mc.onRelease = clickMC;
myMC3_mc.onRelease = clickMC;
function clickMC() {
trace("you clicked the "+this._name+" movie clip.");
};
