Class MouseEventUI<V extends JComponent>

java.lang.Object

javax.swing.plaf.ComponentUI

org.jdesktop.jxlayer.plaf.LayerUI<V>

org.jdesktop.jxlayer.plaf.AbstractLayerUI<V>

org.pbjar.jxlayer.plaf.ext.MouseEventUI<V>

All Implemented Interfaces:

Serializable

Direct Known Subclasses:

TransformUI

public class MouseEventUI<V extends JComponent>
extends org.jdesktop.jxlayer.plaf.AbstractLayerUI<V>

This class provides for MouseEvent re-dispatching. It may be used to set a tool tip on JXLayer's glass pane and still have the child components receive MouseEvents.

Note: A MouseEventUI instance cannot be shared and can be set to a single JXLayer instance only.

Method Summary

Modifier and Type	Method	Description
boolean	contains(JComponent c, int x, int y)	Overridden to override the LayerUI implementation that only consults the view.
void	eventDispatched(AWTEvent event, org.jdesktop.jxlayer.JXLayer<? extends V> layer)	Overridden to allow for re-dispatching of mouse events to their intended (visual) recipients, rather than to the components according to their bounds.
protected org.jdesktop.jxlayer.JXLayer<? extends V>	getInstalledLayer()
long	getLayerEventMask()	Overridden to only get the following event types: AWTEvent.MOUSE_EVENT_MASK, AWTEvent.MOUSE_MOTION_EVENT_MASK and AWTEvent.MOUSE_WHEEL_EVENT_MASK.
void	installUI(JComponent component)	Overridden to check if this LayerUI has not been installed already, and to set the argument component as the installed JXLayer.
protected void	processMouseWheelEvent(MouseWheelEvent event, org.jdesktop.jxlayer.JXLayer<? extends V> jxlayer)	Re-dispatches the event to the first component in the hierarchy that has a MouseWheelListener registered.
void	uninstallUI(JComponent c)	Overridden to remove the installed JXLayer.

Method Detail

contains

public boolean contains(JComponent c,
                        int x,
                        int y)

Overridden to override the LayerUI implementation that only consults the view.

This implementation is a copy of the ComponentUI.contains(JComponent, int, int) method.

Overrides:

contains in class ComponentUI

installUI

public void installUI(JComponent component)
               throws IllegalStateException

Overridden to check if this LayerUI has not been installed already, and to set the argument component as the installed JXLayer.

Overrides:

installUI in class org.jdesktop.jxlayer.plaf.AbstractLayerUI<V extends JComponent>

Throws:

IllegalStateException - when this LayerUI has been installed already

getInstalledLayer()

uninstallUI

public void uninstallUI(JComponent c)

Overridden to remove the installed JXLayer.

Overrides:

uninstallUI in class org.jdesktop.jxlayer.plaf.AbstractLayerUI<V extends JComponent>

getLayerEventMask

public long getLayerEventMask()

Overridden to only get the following event types: AWTEvent.MOUSE_EVENT_MASK, AWTEvent.MOUSE_MOTION_EVENT_MASK and AWTEvent.MOUSE_WHEEL_EVENT_MASK.

Overrides:

getLayerEventMask in class org.jdesktop.jxlayer.plaf.AbstractLayerUI<V extends JComponent>

eventDispatched

public void eventDispatched(AWTEvent event,
                            org.jdesktop.jxlayer.JXLayer<? extends V> layer)

Overridden to allow for re-dispatching of mouse events to their intended (visual) recipients, rather than to the components according to their bounds.

Overrides:

eventDispatched in class org.jdesktop.jxlayer.plaf.AbstractLayerUI<V extends JComponent>

processMouseWheelEvent

protected void processMouseWheelEvent(MouseWheelEvent event,
                                      org.jdesktop.jxlayer.JXLayer<? extends V> jxlayer)

Re-dispatches the event to the first component in the hierarchy that has a MouseWheelListener registered.

Overrides:

processMouseWheelEvent in class org.jdesktop.jxlayer.plaf.AbstractLayerUI<V extends JComponent>

getInstalledLayer

protected org.jdesktop.jxlayer.JXLayer<? extends V> getInstalledLayer()
