de.ipcon.gui.FocusSnitchMap

All Implemented Interfaces:

java.util.Map

public class FocusSnitchMap
extends com.google.common.collect.ForwardingMap

A custom map implementation that wraps a delegate map and logs "put" operations.

This class is a diagnostic tool designed to be used via reflection to replace an internal map within the KeyboardFocusManager (e.g. the "mostRecentFocusOwners" map). By overriding the "put" method, it logs every time a component's focus is set, providing valuable debugging information about focus changes. It uses the tool method FormElementI.toDebugName(Object) to format the component or window for a more readable log message.
