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.

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 TM has been added to the java.beans package. Please see XMLEncoder .

Overrides:
setFont in class JComponent
Parameters:
font - the desired Font for this component
See Also:
Component.getFont()

getFont

Gets the font of this component.

Specified by:
getFont in interface MenuContainer
Overrides:

this component's font; if a font has not been set for this component, the font of its parent is returned
See Also:
Component.setFont(java.awt.Font)

setBackground


public void setBackground(Color color)
Subclassed to map ColorUIResources to null. If color is null, or a ColorUIResource, this has the effect of letting the background color of the JTree show through. On the other hand, if color is non-null, and not a ColorUIResource, the background becomes color.

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

getTreeCellRendererComponent


public Component getTreeCellRendererComponent(JTree tree,
                                              Object value,

                                              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 on leaf and expanded.

Specified by:
getTreeCellRendererComponent in interface TreeCellRenderer
Returns:
the Component that the renderer uses to draw the value
