| ComponentEvent | () | Constructor |
public function ComponentEvent(type:String, bubbles:Boolean = false, cancelable:Boolean = false)
| Language Version : | ActionScript 3.0 |
| Player Version : | Flash Player 9.0.28.0 |
Creates a new ComponentEvent object that contains information about a component event. A ComponentEvent object is passed as a parameter to an event listener.
Parameterstype:String — The type of the event. Event listeners can access this information
through the type property of the event object. A component can
have the following types of events: ComponentEvent.BUTTON_DOWN,
ComponentEvent.ENTER, ComponentEvent.HIDE,
ComponentEvent.LABEL_CHANGE, ComponentEvent.MOVE,
ComponentEvent.RESIZE, ComponentEvent.SHOW.
|
|
bubbles:Boolean (default = false) — Determines whether the ComponentEvent object participates in the
bubbling phase of the event flow. Event listeners can access this information
through the bubbles property of the event object.
|
|
cancelable:Boolean (default = false) — Determines whether the ComponentEvent object can be canceled. Event
listeners can access this information through the cancelable property
of the event object.
|
| clone | () | method |
public override function clone():Event
| Language Version : | ActionScript 3.0 |
| Player Version : | Flash Player 9.0.28.0 |
Creates a copy of the ComponentEvent object and sets the value of each parameter to match the original.
ReturnsEvent — A new ComponentEvent object with property values that match those of the
original.
|
| toString | () | method |
public override function toString():String
| Language Version : | ActionScript 3.0 |
| Player Version : | Flash Player 9.0.28.0 |
Returns a string that contains all the properties of the ComponentEvent object. The string is in the following format:
