/**
* A concrete implementation of {@code MetalTheme} providing
* the original look of the Java Look and Feel, code-named "Steel". Refer
* to {@link MetalLookAndFeel#setCurrentTheme} for details on changing
* the default theme.
*
* All colors returned by {@code DefaultMetalTheme} are completely
* opaque.
*
*
Font Style
*
* {@code DefaultMetalTheme} uses bold fonts for many controls. To make all
* controls (with the exception of the internal frame title bars and
* client decorated frame title bars) use plain fonts you can do either of
* the following:
*
* - Set the system property
swing.boldMetal to
* false. For example,
* java -Dswing.boldMetal=false MyApp.
* - Set the defaults property
swing.boldMetal to
* Boolean.FALSE. For example:
* UIManager.put("swing.boldMetal", Boolean.FALSE);
*
* The defaults property swing.boldMetal, if set,
* takes precedence over the system property of the same name. After
* setting this defaults property you need to re-install
* MetalLookAndFeel, as well as update the UI
* of any previously created widgets. Otherwise the results are undefined.
* The following illustrates how to do this:
*
* // turn off bold fonts
* UIManager.put("swing.boldMetal", Boolean.FALSE);
*
* // re-install the Metal Look and Feel
* UIManager.setLookAndFeel(new MetalLookAndFeel());
*
* // Update the ComponentUIs for all Components. This
* // needs to be invoked for all windows.
* SwingUtilities.updateComponentTreeUI(rootComponent);
*
*
* 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 {@link java.beans.XMLEncoder}.
