Class DragSourceDropEvent

Contents
  • All Implemented Interfaces:
    Serializable

    public class DragSourceDropEvent
extends DragSourceEvent
    The DragSourceDropEvent is delivered from the DragSourceContextPeer, via the DragSourceContext, to the dragDropEnd method of DragSourceListeners registered with that DragSourceContext and with its associated DragSource. It contains sufficient information for the originator of the operation to provide appropriate feedback to the end user when the operation completes.

    1.2

      • DragSourceDropEvent

        public DragSourceDropEvent(DragSourceContext dsc,
                   int action,
                   boolean success)
        Construct a DragSourceDropEvent for a drop, given the DragSourceContext, the drop action, and a boolean indicating if the drop was successful. The coordinates for this DragSourceDropEvent are not specified, so getLocation will return null for this event.

        The argument action should be one of DnDConstants that represents a single action. This constructor does not throw any exception for invalid action.

        Parameters:
        dsc - the DragSourceContext associated with this DragSourceDropEvent
        action - the drop action
        success - a boolean indicating if the drop was successful
        Throws:
        IllegalArgumentException - if dsc is null.

                   int y)
        Construct a DragSourceDropEvent for a drop, given the DragSourceContext, the drop action, a boolean indicating if the drop was successful, and coordinates.

        The argument action should be one of DnDConstants that represents a single action. This constructor does not throw any exception for invalid action.

        action - the drop action
        success - a boolean indicating if the drop was successful
        x - the horizontal coordinate for the cursor location
        y - the vertical coordinate for the cursor location
        Throws:
        IllegalArgumentException - if dsc is null.

        public DragSourceDropEvent(DragSourceContext dsc)
        Construct a DragSourceDropEvent for a drag that does not result in a drop. The coordinates for this DragSourceDropEvent are not specified, so getLocation will return null for this event.
        Parameters:
        dsc - the DragSourceContext
        Throws:
        IllegalArgumentException - if dsc is null.
