Interface DragSourceListener

All Superinterfaces:
EventListener

DragSourceAdapter, DragSourceContext

public interface DragSourceListener
extends EventListener

Disabled: no SafeJ information.

The DragSourceListener defines the event interface for originators of Drag and Drop operations to track the state of the user's gesture, and to provide appropriate "drag over" feedback to the user throughout the Drag and Drop operation.

The drop site is associated with the previous dragEnter() invocation if the latest invocation of dragEnter() on this listener:

 void dragExit(DragSourceEvent dse)
          Called as the cursor's hotspot exits a platform-dependent drop site.
 void dragOver(DragSourceDragEvent dsde)
          Called as the cursor's hotspot moves over a platform-dependent drop site.
 void dropActionChanged(DragSourceDragEvent dsde)
          Called when the user has modified the drop gesture.
 

Method Detail

dragEnter

void dragEnter(DragSourceDragEvent dsde)
Class is disabled.

Called as the cursor's hotspot enters a platform-dependent drop site. This method is invoked when all the following conditions are true:

Parameters:
dsde - the DragSourceDragEvent

dragOver

void dragOver(DragSourceDragEvent dsde)
Class is disabled.

Called as the cursor's hotspot moves over a platform-dependent drop site. This method is invoked when all the following conditions are true:

Parameters:
dsde - the DragSourceDragEvent

dropActionChanged

void dropActionChanged(DragSourceDragEvent dsde)
Class is disabled.

Called when the user has modified the drop gesture. This method is invoked when the state of the input device(s) that the user is interacting with changes. Such devices are typically the mouse buttons or keyboard modifiers that the user is interacting with.

Parameters:
dsde - the DragSourceDragEvent

dragExit

void dragExit(DragSourceEvent dse)
Class is disabled.

Called as the cursor's hotspot exits a platform-dependent drop site. This method is invoked when any of the following conditions are true: OR OR

Parameters:
dse - the DragSourceEvent

dragDropEnd

void dragDropEnd(DragSourceDropEvent dsde)
Class is disabled.

This method is invoked to signify that the Drag and Drop operation is complete. The getDropSuccess() method of the DragSourceDropEvent can be used to determine the termination state. The getDropAction() method returns the operation that the drop site selected to apply to the Drop operation. Once this method is complete, the current DragSourceContext and associated resources become invalid.

Parameters:
dsde - the DragSourceDropEvent
