If not suppressed, this event is received by the drop target (see the DROP-MODE attribute) under the drag cursor when the drag cursor enters the area occupied by the drop target during a drag-drop operation.
Applications typically use this event to determine whether a compatible Natural data format exists on the drag-drop clipboard via the INQ-FORMAT-AVAILABLE action, and to enable or disable a drop by setting the SUPPRESS-DRAG-DROP-EVENT attribute accordingly.
