DragAndDrop.PrepareStartDrag

Clears drag & drop data.

Clears everything stored in the drag & drop object and prepares it so you can write into it for initiating a drag operation.

function OnGUI ()
{
if (Event.current.type == EventType.MouseDrag)
{
// Clear out drag data
DragAndDrop.PrepareStartDrag ();

// Set up what we want to drag
DragAndDrop.paths = { "/Users/joe/myPath.txt" };

// Start the actual drag
DragAndDrop.StartDrag ("Dragging title");

// Make sure no one uses the event after us
Event.current.Use();
}
}
