LookAndFeel

public LookAndFeel()

Method Detail

getActiveLookAndFeelClass

public static java.lang.Class getActiveLookAndFeelClass()

Get the class of the currently active look and feel.

Returns:

The class of the currently active look and feel.

getActiveLookAndFeel

public static java.lang.String getActiveLookAndFeel()

Get the class name of the currently active look and feel.

Returns:

The class name of the currently active look and feel.

getExtendedLookAndFeelInfo

public static LookAndFeel.ExtendedLookAndFeelInfo[] getExtendedLookAndFeelInfo()

Get list of available look and feels.

The complete list of possible look and feels is pruned to those for which the implementing class actually exists.

isMetal

public static boolean isMetal()

Check if Metal look and feel is the current look and feel.

Returns:

true if Metal is the current look and feel.

setLookAndFeel

public static boolean setLookAndFeel(java.lang.String lookAndFeelName)

Sets a new Swing look and feel.

Parameters:

lookAndFeelName - The name of the new look and feel. This is converted to appropriate class name and/or file name references to load the selected look and feel. If the selected look and feel is not available, the default system look and feel is used instead.

Returns:

true if selected look and feel set.

Reflection is used to invoke the alternative look and feel classes so no errors will occur if the libraries implementing the new interfaces are missing from the client system. Some interfaces (e.g., "windows") only work on certain systems because of licensing issues.

setNativeLookAndFeel

public static void setNativeLookAndFeel()

Sets Swing look and feel to native look and feel.

setNiceLookAndFeel

public static void setNiceLookAndFeel()

Sets Swing look and feel to a "nice" look and feel.

We start by checking if the current look and feel is the native look and feel. If not, we leave it alone and do nothing here.

For Windows, a custom look and feel is used which adds font smoothing to the standard native look and feel.

For Mac OS X, the standard native look and feel is always used.

For other systems, we get the currently defined look and feel and see if it is the native look and feel. If so, we substitute the JGoodies Plastic 3D look and feel instead.

isNativeLookAndFeel

public static boolean isNativeLookAndFeel()

Checks if current Look and Feel is system default.

setLookAndFeelByClassName

public static boolean setLookAndFeelByClassName(java.lang.String lookAndFeelClassName,
                                                boolean updateWindows)

Sets a new Swing look and feel by class name.

Parameters:

lookAndFeelClassName - The class name of the new look and feel.

updateWindows - True to update all existing windows to new look and feel.

Returns:

True if selected look and feel set.

setLookAndFeelByClassName

public static boolean setLookAndFeelByClassName(java.lang.String lookAndFeelClassName)

Sets a new Swing look and feel by class name.

Parameters:

lookAndFeelClassName - Class name of new look and feel.
