Inheritance	NativeDragEvent MouseEvent Event Object

Language Version:

ActionScript 3.0

Runtime Versions:

AIR 1.0

Native drag events are dispatched by the interactive objects involved in a drag-and-drop operation.

The initiating object dispatches:

nativeDragStart — When the drag operation begins.
nativeDragUpdate — While the drag operation is in progress.
nativeDragComplete — When the user releases the dragged item (whether or not the drop was accepted).

The initiating object is the interactive object passed that is to the NativeDragManager object in the call to NativeDragManager.doDrag() which began the drag operation.

Potential target interactive objects dispatches:

nativeDragEnter — When the drag gesture passes within the object boundary.
nativeDragOver — While the drag gesture remains within the object boundary.
nativeDragExit — When the drag gesture leaves the object boundary.
nativeDragDrop — When the user releases the dragged item over the object and the object has accepted the drop with an earlier call to NativeDragManager.acceptDragDrop().

Typically a handler for the nativeDragEnter or nativeDragOver event evaluates the data being dragged, along with the drag actions allowed, to determine whether an interactive object can accept a drop. To specify that an interactive object is an eligible target, the event handler must call the NativeDragManager.acceptDrop()function, passing in a reference to the object. If the user releases the mouse button over the designated object, the object becomes the drop target and dispatches the nativeDragDrop event.

Any InteractiveObject type object can be a drag initiator or a drop target.

Creates an Event object with specific information relevant to native drag-and-drop events.

Event objects are passed as parameters to event listeners. Dispatching a native drag event does not trigger the associated behavior.

Parameters

	`type:String` — The type of the event. Possible values are: `NativeDragEvent.NATIVE_DRAG_START`, `NativeDragEvent.NATIVE_DRAG_UPDATE`, `NativeDragEvent.NATIVE_DRAG_ENTER`, `NativeDragEvent.NATIVE_DRAG_OVER`, `NativeDragEvent.NATIVE_DRAG_EXIT`, `NativeDragEvent.NATIVE_DRAG_DROP`, and `NativeDragEvent.NATIVE_DRAG_COMPLETE`.

	`bubbles:Boolean` (default = `false`) — Indicates whether the Event object participates in the bubbling phase of the event flow.

	`cancelable:Boolean` (default = `true`) — Indicates whether the Event object can be canceled.

	`localX:Number` (default = `NaN`) — The horizontal coordinate at which the event occurred relative to the containing sprite.

	`localY:Number` (default = `NaN`) — The vertical coordinate at which the event occurred relative to the containing sprite.

	`relatedObject:InteractiveObject` (default = `null`) — The related interactive display object.

	`clipboard:Clipboard` (default = `null`) — The Clipboard object containing the data to be transfered.

	`allowedActions:NativeDragOptions` (default = `null`) — The NativeDragOptions object defining the allowed actions (move, copy, and link).

	`dropAction:String` (default = `null`) — The current action.

	`controlKey:Boolean` (default = `false`) — Indicates whether the Control key is activated.

	`altKey:Boolean` (default = `false`) — Indicates whether the Alt key is activated.

	`shiftKey:Boolean` (default = `false`) — Indicates whether the Shift key is activated.

	`commandKey:Boolean` (default = `false`) — Indicates whether the Command key is activated.
