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:

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.

setFont

public void setFont(Font font)

Subclassed to map FontUIResources to null. If font is null, or a FontUIResource, this has the effect of letting the font of the JTree show through. On the other hand, if font is non-null, and not a FontUIResource, the font becomes font.

Overrides:

setFont in class JComponent

Parameters:

font - the desired Font for this component

See Also:

Component.getFont()

getFont

public Font getFont()

Gets the font of this component.

Specified by:

getFont in interface MenuContainer

Overrides:

getFont in class Component

Returns:

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(), 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

Returns:

the Component that the renderer uses to draw the value

paint

public void paint(Graphics g)

Paints the value. The background is filled based on selected.

Overrides:
