mx.managers.DragManager

Instead of setting event.handled inside the dragEnter event listener, you must call the

DragManager.acceptDragDrop(event.target)

method.

You cannot set the

action

property of the event object. Instead, you must call the

setFeedback()

method. For example, change the following code:

event.action=DragManager.Link;

to the following:

DragManager.showFeedback(DragManager.LINK);

This applies to all actions:

MOVE

LINK

COPY

NONE

The signature to the

doDrag()

method has changed. There is no longer an

imageInitObj

argument, and there are two new arguments:

mouseEvent

and

allowMove

When using the

doDrag()

method and dragging text-based controls, you should use the

currentTarget

property of the Event object instead of the

target

property. This is because

of the way text-based controls react during the bubbling event phase.

For a detailed description of these changes and a conversion example, see

“Using the drag-

and-drop feature” on page 178
