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.

Constructor Detail

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.

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.
Since:

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.
