---|---|---|---|
Constructor. | Preloader | ||
Adds a child DisplayObject instance to this DisplayObjectContainer instance. | DisplayObjectContainer | ||
Adds a child DisplayObject instance to this DisplayObjectContainer
instance. | DisplayObjectContainer | ||
addEventListener(type:String, listener:Function, useCapture:Boolean = false, priority:int = 0, useWeakReference:Boolean = false):void
Registers an event listener object with an EventDispatcher object so that the listener
receives notification of an event. | EventDispatcher | ||
Indicates whether the security restrictions
would cause any display objects to be omitted from the list returned by calling
the DisplayObjectContainer.getObjectsUnderPoint() method
with the specified point point. | DisplayObjectContainer | ||
Determines whether the specified display object is a child of the DisplayObjectContainer instance or
the instance itself. | DisplayObjectContainer | ||
Dispatches an event into the event flow. | EventDispatcher | ||
Returns a rectangle that defines the area of the display object relative to the coordinate system
of the targetCoordinateSpace object. | DisplayObject | ||
Returns the child display object instance that exists at the specified index. | DisplayObjectContainer | ||
Returns the child display object that exists with the specified name. | DisplayObjectContainer | ||
Returns the index position of a child DisplayObject instance. | DisplayObjectContainer | ||
Returns an array of objects that lie under the specified point and are children
(or grandchildren, and so on) of this DisplayObjectContainer instance. | DisplayObjectContainer | ||
Returns a rectangle that defines the boundary of the display object,
based on the coordinate system defined by the targetCoordinateSpace
parameter, excluding any strokes on shapes. | DisplayObject | ||
Converts the point object from the Stage (global) coordinates
to the display object's (local) coordinates. | DisplayObject | ||
Converts a two-dimensional point from the Stage (global) coordinates to a
three-dimensional display object's (local) coordinates. | DisplayObject | ||
Checks whether the EventDispatcher object has any listeners registered for a specific type
of event. | EventDispatcher | ||
Indicates whether an object has a specified property defined. | Object | ||
Evaluates the bounding box of the display object to see if it overlaps or intersects with the
bounding box of the obj display object. | DisplayObject | ||
Evaluates the display object to see if it overlaps or intersects with the
point specified by the x and y parameters. | DisplayObject | ||
initialize(showDisplay:Boolean, displayClassName:Class, backgroundColor:uint, backgroundAlpha:Number, backgroundImage:Object, backgroundSize:String, displayWidth:Number, displayHeight:Number, libs:Array = null, sizes:Array = null, rslList:Array = null, resourceModuleURLs:Array = null, applicationDomain:ApplicationDomain = null):void
Called by the SystemManager to initialize a Preloader object. | Preloader | ||
Indicates whether an instance of the Object class is in the prototype chain of the object specified
as the parameter. | Object | ||
Converts a three-dimensional point of the three-dimensional display
object's (local) coordinates to a two-dimensional point in the Stage (global) coordinates. | DisplayObject | ||
Converts the point object from the display object's (local) coordinates to the
Stage (global) coordinates. | DisplayObject | ||
Indicates whether the specified property exists and is enumerable. | Object | ||
Called by the SystemManager after it has finished instantiating
an instance of the application class. | Preloader | ||
Removes the specified child DisplayObject instance from the child list of the DisplayObjectContainer instance. | DisplayObjectContainer | ||
Removes a child DisplayObject from the specified index position in the child list of
the DisplayObjectContainer. | DisplayObjectContainer | ||
Removes a listener from the EventDispatcher object. | EventDispatcher | ||
Changes the position of an existing child in the display object container. | DisplayObjectContainer | ||
Sets the availability of a dynamic property for loop operations. | Object | ||
Lets the user drag the specified sprite. | Sprite | ||
Ends the startDrag() method. | Sprite | ||
Swaps the z-order (front-to-back order) of the two specified child objects. | DisplayObjectContainer | ||
Swaps the z-order (front-to-back order) of the child objects at the two specified index positions in the
child list. | DisplayObjectContainer | ||
Returns the string representation of this object, formatted according to locale-specific conventions. | Object | ||
Returns the string representation of the specified object. | Object | ||
Returns the primitive value of the specified object. | Object | ||
Checks whether an event listener is registered with this EventDispatcher object or any of
its ancestors for the specified event type. | EventDispatcher |
