org.jdesktop.swingx.plaf.basic.BasicHeaderUI
public class BasicHeaderUI
Base implementation of Header
UI.
PENDING JW: This implementation is unusual in that it does not keep a reference to the component it controls. Typically, such is only the case if the ui is shared between instances. Historical? A consequence is that the un/install methods need to carry the header as parameter. Which looks funny when at the same time the children of the header are instance fields in this. Should think about cleanup: either get rid off the instance fields here, or reference the header and remove the param (would break subclasses).
PENDING JW: keys for uidefaults are inconsistent - most have prefix "JXHeader." while defaultIcon has prefix "Header."

public static javax.swing.plaf.ComponentUI createUI(javax.swing.JComponent c)
createUI
method that returns an instance of that UI delegate subclass.
If the UI delegate subclass is stateless, it may return an instance
that is shared by multiple components. If the UI delegate is
stateful, then it should return a new instance per component.
The default implementation of this method throws an error, as it
should never be invoked.
public void installUI(javax.swing.JComponent c)
ComponentUI
instance is being installed
as the UI delegate on the specified component. This method should
completely configure the component for the look and feel,
including the following:
LayoutManager
on the component if necessary.
PropertyChangeListener
on the component in order
to detect and respond to component property changes appropriately.
installUI
in class javax.swing.plaf.ComponentUI
c
- the component where this UI delegate is being installeduninstallUI(javax.swing.JComponent)
,
JComponent.setUI(javax.swing.plaf.ComponentUI)
,
JComponent.updateUI()
public void uninstallUI(javax.swing.JComponent c)
installUI
. This method is invoked when this
UIComponent
instance is being removed as the UI delegate
for the specified component. This method should undo the
configuration performed in installUI
, being careful to
leave the JComponent
instance in a clean state (no
extraneous listeners, look-and-feel-specific property objects, etc.).
This should include the following:
uninstallUI
in class javax.swing.plaf.ComponentUI
c
- the component from which this UI delegate is being removed;
this argument is often ignored,
but might be used if the UI object is stateless
and shared by multiple componentsinstallUI(javax.swing.JComponent)
,
JComponent.updateUI()
