Description

If mc is being dragged, _droptarget returns a string indicating the path to the clip over

which

mc hovers (if any). If mc is not hovering over a clip, _droptarget returns undefined.If

mc was previously dragged and then dropped on a clip, _droptarget returns a string indi-

cating the path to the clip upon which

mc was dropped. The path is provided in slash

notation. A movie clip is considered to be “over” another clip if the mouse pointer over-

laps any portion of the target clip. If

mc hovers over two or more overlapping clips, only the

topmost clip is considered the

_droptarget. To detect intersection between any number of

overlapping clips, use MovieClip.hitTest().

Example

The _droptarget property is convenient for creating drag-and-drop interfaces. The following

example demonstrates how to create a simple shopping-basket interface using

_droptarget.

When the

item_mc clip is dropped onto the basket clip, it is allowed to stay in the basket;

otherwise, the

item_mc is returned to its original location:

// Set original location

item_mc.origX = _x;

item_mc.origY = _y;

// Define a function to call when the item is clicked

item_mc.drag = function () {

this.startDrag();

}

// Define a function to call when the item is ...
