| Methods Summary |
|---|
| public static void | addAuxiliaryLookAndFeel(javax.swing.LookAndFeel laf)Adds a LookAndFeel to the list of auxiliary look and feels.
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. The change will only take effect when a new
UI class is created or when the default look and feel is changed
on a component instance.
Note these are not the same as the installed look and feels.

// Ideally we would throw an exception here, but it's too late
// for that.

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

|
| public static boolean | getBoolean(java.lang.Object key)Returns a boolean from the defaults which is associated with

{@code key} is not a {@code Border}, {@code null} is returned.
return getDefaults().getBorder(key);

for the given locale. If the value for

not a {@code Color}, {@code null} is returned.
return getDefaults().getColor(key,l);
|
| public static java.lang.String | getCrossPlatformLookAndFeelClassName()Returns the name of the LookAndFeel class that implements
the default cross platform look and feel -- the Java
Look and Feel (JLF). This value can be overriden by setting the

if (laf != null) {

|
| public static javax.swing.UIManager$LookAndFeelInfo[] | getInstalledLookAndFeels()Returns an array of {@code LookAndFeelInfo}s representing the
{@code LookAndFeel} implementations currently available. The
LookAndFeelInfo objects can be used by an
application to construct a menu of look and feel options for
the user, or to determine which look and feel to set at startup
time. To avoid the penalty of creating numerous {@code
LookAndFeel} objects, {@code LookAndFeelInfo} maintains the
class name of the {@code LookAndFeel} class, not the actual
{@code LookAndFeel} instance.
The following example illustrates setting the current look and feel
from an instance of {@code LookAndFeelInfo}:
UIManager.setLookAndFeel(info.getClassName());
ArrayList iLAFs = new ArrayList(4);
iLAFs.add(new LookAndFeelInfo(
"Metal", "javax.swing.plaf.metal.MetalLookAndFeel"));
iLAFs.add(new LookAndFeelInfo("CDE/Motif",
"com.sun.java.swing.plaf.motif.MotifLookAndFeel"));
// Only include windows on Windows boxs.
String osName = (String)AccessController.doPrivileged(
new GetPropertyAction("os.name"));
if (osName != null && osName.indexOf("Windows") != -1) {
iLAFs.add(new LookAndFeelInfo("Windows",
"com.sun.java.swing.plaf.windows.WindowsLookAndFeel"));
if (Toolkit.getDefaultToolkit().getDesktopProperty(
"win.xpstyle.themeActive") != null) {
iLAFs.add(new LookAndFeelInfo("Windows Classic",
"com.sun.java.swing.plaf.windows.WindowsClassicLookAndFeel"));
}
}
else {
// GTK is not shipped on Windows.
iLAFs.add(new LookAndFeelInfo("GTK+",
"com.sun.java.swing.plaf.gtk.GTKLookAndFeel"));
}
installedLAFs = (LookAndFeelInfo[])iLAFs.toArray(
new LookAndFeelInfo[iLAFs.size()]);
maybeInitialize();
LookAndFeelInfo[] ilafs = installedLAFs;
LookAndFeelInfo[] rv = new LookAndFeelInfo[ilafs.length];
System.arraycopy(ilafs, 0, rv, 0, ilafs.length);
return rv;
|
| public static int | getInt(java.lang.Object key)Returns an integer from the defaults. If the value for
{@code key} is not an {@code Integer}, or does not exist,
{@code 0} is returned.
return getDefaults().getInt(key);
|
| public static int | getInt(java.lang.Object key, java.util.Locale l)Returns an integer from the defaults that is appropriate
for the given locale. If the value for
{@code key} is not an {@code Integer}, or does not exist,
{@code 0} is returned.
return getDefaults().getInt(key,l);
|
| private static javax.swing.UIManager$LAFState | getLAFState()Return the LAFState object, lazily create one if necessary.
All access to the LAFState fields is done via this method,
for example:
getLAFState().initialized = true;
// First check whether we're running on the same thread as
// the last request.
Thread thisThread = Thread.currentThread();
if (thisThread == currentLAFStateThread) {
return currentLAFState;

SwingUtilities2.LAF_STATE_KEY);
if (rv == null) {
SwingUtilities.appContextPut(
SwingUtilities2.LAF_STATE_KEY,
(rv = new LAFState()));
}
}
}
currentLAFStateThread = thisThread;
currentLAFState = rv;
return rv;
|
| public static javax.swing.LookAndFeel | getLookAndFeel()Returns the current look and feel or null.
maybeInitialize();
return getLAFState().lookAndFeel;
|
| public static javax.swing.UIDefaults | getLookAndFeelDefaults()Returns the {@code UIDefaults} from the current look and feel,
that were obtained at the time the look and feel was installed.
In general, developers should use the {@code UIDefaults} returned from
{@code getDefaults()}. As the current look and feel may expect
certain values to exist, altering the {@code UIDefaults} returned
from this method could have unexpected results.
maybeInitialize();
return getLAFState().getLookAndFeelDefaults();
|
| private static javax.swing.LookAndFeel | getMultiLookAndFeel()Finds the Multiplexing LookAndFeel.
LookAndFeel multiLookAndFeel = getLAFState().multiLookAndFeel;
if (multiLookAndFeel == null) {

|
| public static java.beans.PropertyChangeListener[] | getPropertyChangeListeners()Returns an array of all the PropertyChangeListeners added
to this UIManager with addPropertyChangeListener().
synchronized(classLock) {
return getLAFState().getPropertyChangeSupport(true).
getPropertyChangeListeners();
}
|
| public static java.lang.String | getString(java.lang.Object key)Returns a string from the defaults. If the value for
{@code key} is not a {@code String}, {@code null} is returned.
return getDefaults().getString(key);
|
| public static java.lang.String | getString(java.lang.Object key, java.util.Locale l)Returns a string from the defaults that is appropriate for the
given locale. If the value for
{@code key} is not a {@code String}, {@code null} is returned.
return getDefaults().getString(key,l);
|
| static java.lang.String | getString(java.lang.Object key, java.awt.Component c)Returns a string from the defaults that is appropriate for the
given locale. If the value for
{@code key} is not a {@code String}, {@code null} is returned.
Locale l = (c == null) ? Locale.getDefault() : c.getLocale();
return getString(key, l);
|
| public static java.lang.String | getSystemLookAndFeelClassName()Returns the name of the LookAndFeel class that implements
the native system look and feel if there is one, otherwise
the name of the default cross platform LookAndFeel
class. This value can be overriden by setting the
swing.systemlaf system property.
String systemLAF = (String)AccessController.doPrivileged(
new GetPropertyAction("swing.systemlaf"));
if (systemLAF != null) {
return systemLAF;
}
String osName = (String)AccessController.doPrivileged(

}
}
}
return getCrossPlatformLookAndFeelClassName();
|
| public static javax.swing.plaf.ComponentUI | getUI(javax.swing.JComponent target)Returns the appropriate {@code ComponentUI} implementation for
{@code target}. Typically, this is a cover for
{@code getDefaults().getUI(target)}. However, if an auxiliary
look and feel has been installed, this first invokes
{@code getUI(target)} on the multiplexing look and feel's
defaults, and returns that value if it is {@code non-null}.
maybeInitialize();
ComponentUI ui = null;
LookAndFeel multiLAF = getLAFState().multiLookAndFeel;
if (multiLAF != null) {
// This can return null if the multiplexing look and feel
// doesn't support a particular UI.
ui = multiLAF.getDefaults().getUI(target);

A value of {@code null} can be used to set the look and feel
to {@code null}. As the {@code LookAndFeel} is required for
most of Swing to function, setting the {@code LookAndFeel} to
