interface XAutoscroll
Description Interface for autoscroll support. During Drag and Drop operations it is possible that a user may wish to drop the subject of the operation on a region of a scrollable GUI control that is not currently visible to the user. In such situations it is desirable that the GUI control detect this and institute a scroll operation in order to make obscured region(s) visible to the user. This feature is known as autoscrolling. If a GUI control is both an active DropTarget and is also scrollable, it can receive notifications of autoscrolling gestures by the user from the Drag and Drop system by implementing this interface. An autoscrolling gesture is initiated by the user by keeping the drag cursor motionless with a border region of the Component, referred to as the "autoscrolling region", for a predefined period of time, this will result in repeated scroll requests to the Component until the drag Cursor resumes its motion.
