All Known Implementing Classes:

DraggablePoint

public interface Draggable

An interface that can be implemented by an object that can be dragged with the mouse.

Method Summary

Modifier and Type	Method and Description
void	continueDrag(MouseEvent evt) Continue a drag that was started in startDrag().
void	finishDrag(MouseEvent evt) Finish a draw that was started in startDrag().
boolean	startDrag(MouseEvent evt) Tell the object that a drag operation might be beginning.

Method Detail

startDrag

boolean startDrag(MouseEvent evt)

Tell the object that a drag operation might be beginning. The Draggable object can decide whether it really wants to be dragged, based on the MouseEvent. It should return true to indicate that a drag should really be started, and false if it wants to ignore the MouseEvent.

continueDrag

void continueDrag(MouseEvent evt)

Continue a drag that was started in startDrag(). Presumably the event is a mouseDragged event.

finishDrag

void finishDrag(MouseEvent evt)

Finish a draw that was started in startDrag(). Presumably the event is a mouseReleased event.
