Method Detail

propertyChange

public void propertyChange(java.beans.PropertyChangeEvent evt)

Invalidates the cached laf states, if the UIManager has fired any property change event. Since we need to handle look&feel changes only, we check the event's property name to be "lookAndFeel" or null. The check for null is necessary to handle the special event where property name, old and new value are all null to indicate that multiple properties have changed.

propertyChange in interface java.beans.PropertyChangeListener

evt - describes the property change
