Class MouseBoundsListener

java.lang.Object
  java.awt.event.MouseAdapter
      com.antelmann.util.gui.MouseBoundsListener

All Implemented Interfaces:

MouseListener, MouseMotionListener, EventListener, MouseInputListener

public class MouseBoundsListener
extends MouseAdapter
implements MouseInputListener

a listener class for moving/resizing a component via mouse movements. For proper functionality, the MouseBoundsListener must be registered with the component as both, MouseListener and MouseMotionListener. Note: the resizing doesn't quite work, yet; this class is currently limited to moving a component.

Nested Class Summary

static interface

MouseBoundsListener.Snapper

Constructor Summary

MouseBoundsListener(Component c)

MouseBoundsListener(Component c, Container parent)

MouseBoundsListener(Component c, Container parent, MouseBoundsListener.Snapper snapper, boolean continuousSnapping)

MouseBoundsListener(Component c, MouseBoundsListener.Snapper snapper)

MouseBoundsListener(Component c, MouseBoundsListener.Snapper snapper, boolean continuousSnapping)

Method Summary

Rectangle	getDragOrigin() returns the bounds from where the component is dragged or null if the component is currently not dragged
Insets	getInsets() defines the tolerance for resizing versus moving if a drag at the edge of the component occurs; 2 pixels on every edge by default
Container	getParent()
MouseBoundsListener.Snapper	getSnapper()
boolean	isContinuousSnapping()
void	mouseDragged(MouseEvent ev)
void	mouseMoved(MouseEvent ev)
void	mousePressed(MouseEvent ev)
void	mouseReleased(MouseEvent ev) checks whether there are any limits on the drag target and then snaps to the given bounds
void	setContinuousSnapping(boolean flag)
void	setInsets(Insets insets)
void	setParent(Container parent)
void	setSnapper(MouseBoundsListener.Snapper snapper) defines the snapping behavior while dragging this component
