Constructor Detail

EnhancedPanel

public EnhancedPanel(LayoutManager layout,
                     boolean isDoubleBuffered)
Creates a new EnhancedPanel with the specified layout manager and buffering strategy.

Parameters:
layout - The LayoutManager to use.
isDoubleBuffered - A boolean, true for double-buffering, which uses additional memory space to achieve fast, flicker-free updates.

EnhancedPanel

public EnhancedPanel(LayoutManager layout)
Create a new buffered EnhancedPanel with the specified layout manager.

Parameters:
layout - The LayoutManager to use.

EnhancedPanel

public EnhancedPanel(boolean isDoubleBuffered)
Creates a new EnhancedPanel with FlowLayout and the specified buffering strategy. If isDoubleBuffered is true, the EnhancedPanel will use a double buffer.

Parameters:
isDoubleBuffered - A boolean, true for double-buffering, which uses additional memory space to achieve fast, flicker-free updates.

EnhancedPanel

public EnhancedPanel()
Creates a new EnhancedPanel with a double buffer and a flow layout.

Method Detail

coalesceEvents

@Deprecated
protected AWTEvent coalesceEvents(AWTEvent existingEvent,
                                             AWTEvent newEvent)
Deprecated. See EnhancedPanel.

Overridden in order to prevent this component to deliver a PanelEvent multiple times from the same source.

Overrides:
coalesceEvents in class Component

processEvent

@Deprecated
protected void processEvent(AWTEvent event)
Deprecated. See EnhancedPanel.

Overridden in order to process PanelEvents.

Overrides:
processEvent in class Container

processPanelEvent

protected void processPanelEvent(PanelEvent event)
Calls fireAncestorWindowShown(de.schlichtherle.truezip.swing.PanelEvent) or fireAncestorWindowHidden(de.schlichtherle.truezip.swing.PanelEvent), depending on the ID of the given event.

getAncestorWindow

@Nullable
public Window getAncestorWindow()
Returns the ancestor Window of this Panel or null if the component is not (yet) placed in a Window.

getAncestorWindow

@Nullable
private static Window getAncestorWindow(Component c)

addPanelListener

public void addPanelListener(PanelListener listener)
Adds the listener to the list of receivers for PanelEvents.

Note that the listener doesn't get serialized with this component!

Parameters:
listener - The listener to add. If this method is called n times with the same listener, any events generated will be delivered to this listener n times.

removePanelListener

public void removePanelListener(PanelListener listener)
Removes the listener from the list of receivers for PanelEvents.

Parameters:
listener - The listener to remove. If this listener has been added multiple times, it is removed from the list only once.

getPanelListeners

public PanelListener[] getPanelListeners()
Returns an array of all the panel listeners registered on this component.

Returns:
All of this panel's PanelListeners or an empty array if no panel listeners are currently registered.
See Also:
addPanelListener(de.schlichtherle.truezip.swing.PanelListener), removePanelListener(de.schlichtherle.truezip.swing.PanelListener)

fireAncestorWindowShown

void fireAncestorWindowShown(PanelEvent event)
Notifies all registered listeners about the event. This is a synchronous operation.

Parameters:
event - The event to be fired.

fireAncestorWindowHidden

void fireAncestorWindowHidden(PanelEvent event)
Notifies all registered listeners about the event. This is a synchronous operation.

Parameters:
event - The event to be fired.
