Method Detail getBooleanSystemProperty public static Boolean getBooleanSystemProperty(String key, String logMessage)(Code) Checks if a boolean system property has been set for the given key, and returns the associated Boolean, or null if no value has been set. The test for the property ignores case. If a Boolean value has been set, a message is logged with the given prefix. Parameters:   key - the key used to lookup the system property value Parameters:   logMessage - a prefix used when a message is logged Boolean.TRUE if the system property has been set to "true" (case ignored), Boolean.FALSE if it has been set to "false", null otherwise getDefaultTheme public static Object getDefaultTheme(LookAndFeel laf)(Code) getInstalledThemes public static List getInstalledThemes(LookAndFeel laf)(Code) getSlightlyBrighter public static Color getSlightlyBrighter(Color color)(Code) Computes and returns a Color that is slightly brighter than the specified Color. Parameters:   color - the color used as basis for the brightened color a slightly brighter color getSlightlyBrighter public static Color getSlightlyBrighter(Color color, float factor)(Code) Computes and returns a Color that is slightly brighter than the specified Color. Parameters:   color - the color used as basis for the brightened color Parameters:   factor - the factor used to compute the brightness a slightly brighter color getSystemProperty public static String getSystemProperty(String key)(Code) Tries to look up the System property for the given key. In untrusted environments this may throw a SecurityException. In this case we catch the exception and answer null. Parameters:   key - the name of the system property the system property's String value, or null if there'sno such value, or a SecurityException has been caught getSystemProperty public static String getSystemProperty(String key, String defaultValue)(Code) Tries to look up the System property for the given key. In untrusted environments this may throw a SecurityException. In this case, we catch the exception and answer the default value. Parameters:   key - the name of the system property Parameters:   defaultValue - the default value if no property exists. the system property's String value, or the defaultValue if there's no such value, or a SecurityException has been caught getToolkitUsesNativeDropShadows public static boolean getToolkitUsesNativeDropShadows()(Code) Checks and answers whether this toolkit provides native drop shadows for popups such as the Mac OS X. Currently this is used to determine if the Looks' popup drop shadow feature is active or not - even if it's enabled. true if the toolkit provides native drop shadows See Also:   Options.isPopupDropShadowActive isTrueColor public static boolean isTrueColor(Component c)(Code) Checks and answers whether we have a true color system. Parameters:   c - the component used to determine the toolkit true if the component's toolkit has a pixel size >= 24 log public static void log()(Code) Prints a new line to the console if logging is enabled. log public static void log(String message)(Code) Prints the given message to the console if logging is enabled. Parameters:   message - the message to print setLoggingEnabled public static void setLoggingEnabled(boolean enabled)(Code) Enables or disables the Looks logging. Parameters:   enabled - true to enable logging, false to disable it setLookAndTheme public static void setLookAndTheme(LookAndFeel laf, Object theme) throws UnsupportedLookAndFeelException(Code) Methods inherited from java.lang.Object native protected Object clone() throws CloneNotSupportedException(Code)(Java Doc) public boolean equals(Object obj)(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) final native public Class getClass()(Code)(Java Doc) native public int hashCode()(Code)(Java Doc) final native public void notify()(Code)(Java Doc) final native public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final native public void wait(long timeout) throws InterruptedException(Code)(Java Doc) final public void wait(long timeout, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
