The 'onDragLeave' callback

Event generated under Windows only

Event number: 36
Valid for: Any visible control

The onDragLeave callback is invoked for the target control when a potential drag-and-drop operation has begun, but the user moves the mouse out of the target control. (A potential drag-and-drop operation occurs when the user drags a source control onto a target control and the sourceformats property of the source is compatible with the targetformats property of the target, but before the user releases the mouse to complete the operation).

The dragsource property will contain the name of the control being dragged.

The event-specific parameters in ⎕EV are (in index origin 1):
