## Uses of Interface
javax.swing.event.TreeExpansionListener

Packages that use TreeExpansionListener
com.sun.java.accessibility.util: Provides a collection of interfaces and classes that compose the Java Accessibility Utilities.
javax.swing: Provides a set of "lightweight" (all-Java language) components that, to the maximum degree possible, work the same on all platforms.
javax.swing.plaf.basic: Provides user interface objects built according to the Basic look and feel.

### Uses of TreeExpansionListener in com.sun.java.accessibility.util

Methods in com.sun.java.accessibility.util with parameters of type TreeExpansionListener
`static void` SwingEventMonitor.`addTreeExpansionListener​(TreeExpansionListener l)` Adds the specified listener to receive all `TREEEXPANSION` events on each component instance in the Java Virtual Machine as they occur.
`static void` SwingEventMonitor.`removeTreeExpansionListener​(TreeExpansionListener l)` Removes the specified listener so it no longer receives `TREEEXPANSION` events when they occur.

### Uses of TreeExpansionListener in javax.swing

Classes in javax.swing that implement TreeExpansionListener
`protected class` `JTree.AccessibleJTree` This class implements accessibility support for the `JTree` class.

Methods in javax.swing that return TreeExpansionListener
`TreeExpansionListener[]` JTree.`getTreeExpansionListeners()` Returns an array of all the `TreeExpansionListener`s added to this JTree with addTreeExpansionListener().

Methods in javax.swing with parameters of type TreeExpansionListener
`void` JTree.`addTreeExpansionListener​(TreeExpansionListener tel)` Adds a listener for `TreeExpansion` events.
`void` JTree.`removeTreeExpansionListener​(TreeExpansionListener tel)` Removes a listener for `TreeExpansion` events.

### Uses of TreeExpansionListener in javax.swing.plaf.basic

Classes in javax.swing.plaf.basic that implement TreeExpansionListener
`class` `BasicTreeUI.TreeExpansionHandler` Updates the TreeState in response to nodes expanding/collapsing.

Methods in javax.swing.plaf.basic that return TreeExpansionListener
`protected TreeExpansionListener` BasicTreeUI.`createTreeExpansionListener()` Creates and returns the object responsible for updating the treestate when nodes expanded state changes.
