시스템 L & F 사용

스윙은 네이티브 L & F를 상당 부분 지원합니다.
특정 L & F 등급을 요구하지 않고도 언제든지 쉽게 설치할 수 있습니다.

public class SystemLookAndFeel
{
    public static void main ( final String[] args )
    {
        // L&F installation should be performed within EDT (Event Dispatch Thread)
        // This is important to avoid any UI issues, exceptions or even deadlocks
        SwingUtilities.invokeLater ( new Runnable ()
        {
            @Override
            public void run ()
            {
                // Process of L&F installation might throw multiple exceptions
                // It is always up to you whether to handle or ignore them
                // In most common cases you would never encounter any of those
                try
                {
                    // Installing native L&F as a current application L&F
                    // We do not know what exactly L&F class is, it is provided by the UIManager
                    UIManager.setLookAndFeel ( UIManager.getSystemLookAndFeelClassName () );
                }
                catch ( final ClassNotFoundException e )
                {
                    // L&F class was not found
                    e.printStackTrace ();
                }
                catch ( final InstantiationException e )
                {
                    // Exception while instantiating L&F class
                    e.printStackTrace ();
                }
                catch ( final IllegalAccessException e )
                {
                    // Class or initializer isn't accessible
                    e.printStackTrace ();
                }
                catch ( final UnsupportedLookAndFeelException e )
                {
                    // L&F is not supported on the current system
                    e.printStackTrace ();
                }

                // Now we can create some natively-looking UI
                // This is just a small sample frame with a single button on it
                final JFrame frame = new JFrame ();
                final JPanel content = new JPanel ( new FlowLayout () );
                content.setBorder ( BorderFactory.createEmptyBorder ( 50, 50, 50, 50 ) );
                content.add ( new JButton ( "Native-looking button" ) );
                frame.setContentPane ( content );
                frame.setDefaultCloseOperation ( WindowConstants.EXIT_ON_CLOSE );
                frame.pack ();
                frame.setLocationRelativeTo ( null );
                frame.setVisible ( true );
            }
        } );
    }
}

JDK가 지원하는 기본 L & F입니다 (OS -> L & F).

*이 L & F는 시스템 공급 업체가 제공하며 실제 L & F 클래스 이름은 다를 수 있습니다.

커스텀 L & F 사용하기

public class CustomLookAndFeel
{
    public static void main ( final String[] args )
    {
        // L&F installation should be performed within EDT (Event Dispatch Thread)
        // This is important to avoid any UI issues, exceptions or even deadlocks
        SwingUtilities.invokeLater ( new Runnable ()
        {
            @Override
            public void run ()
            {
                // Process of L&F installation might throw multiple exceptions
                // It is always up to you whether to handle or ignore them
                // In most common cases you would never encounter any of those
                try
                {
                    // Installing custom L&F as a current application L&F
                    UIManager.setLookAndFeel ( "javax.swing.plaf.metal.MetalLookAndFeel" );
                }
                catch ( final ClassNotFoundException e )
                {
                    // L&F class was not found
                    e.printStackTrace ();
                }
                catch ( final InstantiationException e )
                {
                    // Exception while instantiating L&F class
                    e.printStackTrace ();
                }
                catch ( final IllegalAccessException e )
                {
                    // Class or initializer isn't accessible
                    e.printStackTrace ();
                }
                catch ( final UnsupportedLookAndFeelException e )
                {
                    // L&F is not supported on the current system
                    e.printStackTrace ();
                }

                // Now we can create some pretty-looking UI
                // This is just a small sample frame with a single button on it
                final JFrame frame = new JFrame ();
                final JPanel content = new JPanel ( new FlowLayout () );
                content.setBorder ( BorderFactory.createEmptyBorder ( 50, 50, 50, 50 ) );
                content.add ( new JButton ( "Metal button" ) );
                frame.setContentPane ( content );
                frame.setDefaultCloseOperation ( WindowConstants.EXIT_ON_CLOSE );
                frame.pack ();
                frame.setLocationRelativeTo ( null );
                frame.setVisible ( true );
            }
        } );
    }
}
