All Implemented Interfaces:

MouseListener, MouseMotionListener, Iterable<Drawable>, EventListener, MouseInputListener, Constants

public class PanelPaintDevice
extends PaintDevice
implements MouseInputListener, Constants

A PanelPaintDevice is a PaintDevice implementation that uses a JPanel (see getPanel()) for displaying diagrams. Its main benefit is that - in contrast to other PaintDevice implementations - it does not allocate extra memory.

Constructor Detail

PanelPaintDevice

public PanelPaintDevice(boolean interactive)

Creates a new PanelPaintDevice.

Parameters:

interactive - flag denoting if the PanelPaintDevice is interactive, meaning that it reacts to mouse movement and clicks

Method Detail

setDiagram

public void setDiagram(Diagram diagram)

Overrides:

setDiagram in class PaintDevice

mouseMoved

public void mouseMoved(MouseEvent e)

This method is called when the mouse moved over the panel. If it has exited or entered a drawable object, PanelPaintDeviceListeners are notified.

Specified by:

mouseMoved in interface MouseMotionListener

Parameters:

e -

addListener

public void addListener(PanelPaintDeviceListener ppdl)

Adds a PanelPaintDeviceListener that will be notified when the mouse enters, exits or clicks drawable objects

Parameters:

ppdl - a a PanelPaintDeviceListener

close

public void close()

Description copied from class: PaintDevice

This method is called once when no Drawable object will be added anymore. Its default implementation is empty.

Overrides:

close in class PaintDevice
