# Class DefaultTreeCellRenderer

java.lang.Object
java.awt.Component
java.awt.Container
javax.swing.JComponent
javax.swing.JLabel
javax.swing.tree.DefaultTreeCellRenderer

All Implemented Interfaces:
  `ImageObserver, MenuContainer, Serializable, Accessible, SwingConstants, TreeCellRenderer`

public class DefaultTreeCellRenderer extends JLabel implements TreeCellRenderer
Displays an entry in a tree. `DefaultTreeCellRenderer` is not opaque and unless you subclass paint you should not change this. See How to Use Trees in The Java Tutorial for examples of customizing node display using this class.

The set of icons and colors used by `DefaultTreeCellRenderer` can be configured using the various setter methods. The value for each property is initialized from the defaults table. When the look and feel changes (`updateUI` is invoked), any properties that have a value of type `UIResource` are refreshed from the defaults table. The following table lists the mapping between `DefaultTreeCellRenderer` property and defaults table key:

Properties
Property | Key
--- | ---
"leafIcon" | "Tree.leafIcon"
"closedIcon" | "Tree.closedIcon"
"openIcon" | "Tree.openIcon"
"textSelectionColor" | "Tree.selectionForeground"
"textNonSelectionColor" | "Tree.textForeground"
"backgroundSelectionColor" | "Tree.selectionBackground"
"backgroundNonSelectionColor" | "Tree.textBackground"
"borderSelectionColor" | "Tree.selectionBorderColor"

Implementation Note: This class overrides `invalidate`, `validate`, `revalidate`, `repaint`, and `firePropertyChange` solely to improve performance. If not overridden, these frequently called methods would execute code paths that are unnecessary for the default tree cell renderer. If you write your own renderer, take care to weigh the benefits and drawbacks of overriding these methods.

Warning: Serialized objects of this class will not be compatible with future Swing releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of Swing. As of 1.4, support for long term storage of all JavaBeans has been added to the `java.beans` package. Please see `XMLEncoder`.

Overrides:
  `setFont` in class `JComponent`
Parameters:
  `font` - the desired `Font` for this component

Overrides:
  `setBackground` in class `JComponent`
Parameters:
  `color` - the desired background `Color`
See Also:
  - `Component.getBackground()`
  - `JComponent.setOpaque(boolean)`

### getTreeCellRendererComponent

public Component getTreeCellRendererComponent(JTree tree, Object value, boolean sel, boolean expanded, boolean leaf, int row, boolean hasFocus)
Configures the renderer based on the passed in components. The value is set from messaging the tree with `convertValueToText`, which ultimately invokes `toString` on `value`. The foreground color is set based on the selection and the icon is set based on the `leaf` and `expanded` parameters.

Specified by:
  `getTreeCellRendererComponent` in interface `TreeCellRenderer`
Parameters:
  `tree` - the receiver is being configured for
  `value` - the value to render
  `sel` - whether node is selected
  `expanded` - whether node is expanded
