Class com.sun.java.swing.UIManager

java.lang.Object
   |
   +----com.sun.java.swing.UIManager

public class UIManager

extends Object

implements Serializable

We manage three levels of defaults: user defaults, look and feel defaults, system defaults. A call to UIManager.get() checks all three levels in order and returns the first non-null value for a key, if any. A call to UIManager.put() just affects the user defaults. Note that a call to setLookAndFeel() doesn't affect the user defaults, it just replaces the middle defaults "level".

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 Swing1.0 applications. It will not be possible to load serialized Swing1.0 objects with future releases of Swing. The JDK1.2 release of Swing will be the compatibility baseline for the serialized form of Swing objects.

UIManager()

addPropertyChangeListener(PropertyChangeListener)

Add a PropertyChangeListener to the listener list.

get(Object)

getAuxiliaryLookAndFeels()

Return the list of auxiliary look and feels (can be null).

getBorder(Object)

getColor(Object)

getCrossPlatformLookAndFeelClassName()

Returns the name of the LookAndFeel class that implements the default cross platform look and feel, i.e.

getDefaults()

getFont(Object)

getIcon(Object)

getInstalledLookAndFeels()

Return an array of objects that provide some information about the LookAndFeel implementations that have been installed with this java development kit.

getLookAndFeel()

Returns The current default look and feel, or null.

getLookAndFeelDefaults()

getString(Object)

getSystemLookAndFeelClassName()

Returns the name of the LookAndFeel class that implements the native systems look and feel if there is one, otherwise the name of the default cross platform LookAndFeel class.

getUI(JComponent)

installLookAndFeel(String, String)

installLookAndFeel(UIManager. LookAndFeelInfo)

Adds the specified look and feel to the current array and then calls setInstalledLookAndFeels.

put(Object, Object)

removePropertyChangeListener(PropertyChangeListener)

Remove a PropertyChangeListener from the listener list.

setInstalledLookAndFeels(UIManager. LookAndFeelInfo[])

Replaces the current array of installed LookAndFeelInfos.

setLookAndFeel(LookAndFeel)

Set the current default look and feel.

setLookAndFeel(String)

 public UIManager()

 public static UIManager. LookAndFeelInfo[] getInstalledLookAndFeels()

Return an array of objects that provide some information about the LookAndFeel implementations that have been installed with this java development kit. The LookAndFeel info objects can be used by an application to construct a menu of look and feel options for the user or to set the look and feel at start up time. Note that we do not return the LookAndFeel classes themselves here to avoid the cost of unnecessarily loading them.

Given a LookAndFeelInfo object one can set the current look and feel like this:

 UIManager.setLookAndFeel(info.getClassName());

 public static void setInstalledLookAndFeels(UIManager. LookAndFeelInfo infos[]) throws SecurityException

Replaces the current array of installed LookAndFeelInfos.

getInstalledLookAndFeels

 public static void installLookAndFeel(UIManager. LookAndFeelInfo info)

Adds the specified look and feel to the current array and then calls setInstalledLookAndFeels.

 public static void installLookAndFeel(String name,
                                       String className)

 public static LookAndFeel getLookAndFeel()

Returns The current default look and feel, or null.

Returns:

The current default look and feel, or null.

See Also:

setLookAndFeel

 public static void setLookAndFeel(LookAndFeel newLookAndFeel) throws UnsupportedLookAndFeelException

Set the current default look and feel.

This is a JavaBeans bound property.

Throws: UnsupportedLookAndFeelException

If lnf.isSupportedLookAndFeel() is false.

See Also:

getLookAndFeel

 public static void setLookAndFeel(String className) throws ClassNotFoundException, InstantiationException, IllegalAccessException, UnsupportedLookAndFeelException

Throws: ClassNotFoundException

If the LookAndFeel class could not be found.

Throws: InstantiationException

If a new instance of the class couldn't be creatd.

Throws: IllegalAccessException

If the class or initializer isn't accessible.

Throws: UnsupportedLookAndFeelException

If lnf.isSupportedLookAndFeel() is false.

 public static String getSystemLookAndFeelClassName()

Returns the name of the LookAndFeel class that implements the native systems look and feel if there is one, otherwise the name of the default cross platform LookAndFeel class.

See Also:

setLookAndFeel, getCrossPlatformLookAndFeelClassName

 public static String getCrossPlatformLookAndFeelClassName()

Returns the name of the LookAndFeel class that implements the default cross platform look and feel, i.e. the "metal" look and feel.

Returns:

"com.sun.java.swing.plaf.metal.MetalLookAndFeel"

 public static UIDefaults getDefaults()

 public static Font getFont(Object key)

 public static Color getColor(Object key)

 public static Icon getIcon(Object key)

 public static Border getBorder(Object key)

 public static String getString(Object key)

 public static Object get(Object key)

                          Object value)

 public static ComponentUI getUI(JComponent target)

 public static UIDefaults getLookAndFeelDefaults()

 public static LookAndFeel[] getAuxiliaryLookAndFeels()

Return the list of auxiliary look and feels (can be null). The auxiliary look and feels tell the multiplexing look and feel what other LookAndFeel classes for a component instance are to be used in addition to the default LookAndFeel class when creating a multiplexing UI.

Note these are not the same as the installed look and feels.

Parameters:

listener - The PropertyChangeListener to be added
