flash.desktop.NativeDragOptions - Adobe® Flex® 4 Language Reference (Flex 4)

Package	flash.desktop
Class	public class NativeDragOptions
Inheritance	NativeDragOptions Object

Language Version:

ActionScript 3.0

Runtime Versions:

AIR 1.0

The NativeDragOptions class defines constants for the names of drag-and-drop actions allowed in a drag-and-drop operation.

Drag actions are part of a feedback mechanism to allow the initiating and target objects to cooperate in the drag-and-drop exchange. The actions are only a hint to the operating system. It is up to the drag initiator and target objects involved in the transaction to implement the proper behavior.

An initiating object should only allow the actions that it supports. For example, an initiating object should allow the move action only if that object's internal logic removes the source data when a target accepts a drop with a move action.

A new NativeDragOptions object has all properties initialized to true (all actions allowed).

Method Detail

toString

()

method

public function toString():String

Runtime Versions:

AIR 1.0

Returns the string representation of the specified object.

Note: Methods of the Object class are dynamically created on Object's prototype. To redefine this method in a subclass of Object, do not use the override keyword. For example, a subclass of Object implements function toString():String instead of using an override of the base class.

Returns

String — A string representation of the object.
