## Class DragSourceDropEvent

- java.lang.Object
- - java.util.EventObject
  - - java.awt.dnd.DragSourceEvent
    - - java.awt.dnd.DragSourceDropEvent

- All Implemented Interfaces:
    Serializable

      public class DragSourceDropEvent
      extends DragSourceEvent

  The `DragSourceDropEvent` is delivered from the `DragSourceContextPeer`, via the `DragSourceContext`, to the `dragDropEnd` method of `DragSourceListener`s 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.

    - #### 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`.

        `DragSourceEvent.getLocation()`

    - #### DragSourceDropEvent

          public DragSourceDropEvent(DragSourceContext dsc,
                                     int action,
                                     boolean success,
                                     int x,
                                     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`.

      Parameters:
        `dsc` - the `DragSourceContext` associated with this `DragSourceDropEvent`
        `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`.

    - #### DragSourceDropEvent

          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`.

        `DragSourceEvent.getLocation()`

  - ### Method Detail

    - #### getDropSuccess

          public boolean getDropSuccess()

      This method returns a `boolean` indicating if the drop was successful.
      Returns:
        `true` if the drop target accepted the drop and successfully performed a drop action; `false` if the drop target rejected the drop or if the drop target accepted the drop, but failed to perform a drop action.

    - #### getDropAction

          public int getDropAction()

      This method returns an `int` representing the action performed by the target on the subject of the drop.
      Returns:
        the action performed by the target on the subject of the drop if the drop target accepted the drop and the target drop action is supported by the drag source; otherwise, `DnDConstants.ACTION_NONE`.
