Swing Make Over

Swing Make Over merupakan tehnik memanipulasi tampilan aplikasi java gui (Swing) agar terlihat lebih keren dan sesuai dengan yang kita inginkan.  

Contoh :

• Button Swing Make Over
  Buat java class dengan nama sesuai selera misalnya dengan nama ButtonMakeOver. Sourcenya :
  
  import java.awt.Color;

  import java.awt.GradientPaint;

  import java.awt.Graphics;

  import java.awt.Graphics2D;

  import java.awt.RenderingHints;

  import javax.swing.ButtonModel;

  import javax.swing.JButton;

  public class ButtonMakeOver extends JButton {

      public ButtonMakeOver(String text) {

     setText(text);

          setBorderPainted(false);

          setContentAreaFilled(false);

          setFocusPainted(false);

          setOpaque(false);

          setForeground(Color.white);

      }

      @Override

      protected void paintComponent(Graphics g) {

          ButtonModel buttonModel = getModel();

          Graphics2D gd = (Graphics2D) g.create();

                  gd.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);

                  gd.setPaint(new   GradientPaint(0,   0,   Color.white,   0, getHeight(), new Color(0, 0, 0, 0)));

          if (buttonModel.isRollover()) {

              gd.setPaint(new GradientPaint(0, 0, new Color(0, 0, 0, 0), 0, getHeight(), Color.white));

              if (buttonModel.isPressed()) {

                  gd.setPaint(new GradientPaint(0, 0, Color.white, 0, getHeight(), Color.white));

                  setForeground(Color.BLACK);

              } else {

                  setForeground(Color.white);

              }

          }

          gd.fillRoundRect(0, 0, getWidth(), getHeight(), 25, 25);

          gd.dispose();

          super.paintComponent(g);

      }

  }
  Tulis source codeberikut (Test.java) :
  
  import java.awt.BorderLayout;

  import java.awt.Color;

  import javax.swing.JFrame;

  import javax.swing.JPanel;

  public class Test extends JFrame {

      private ButtonMakeOver button =new ButtonMakeOver("My Button");

      private JPanel panel;

      public Test() {

          panel = new JPanel(null);

          panel.setBackground(Color.BLACK);

          panel.add(button);

          button.setBounds(20, 20, 120, 23);

          setLayout(new BorderLayout());

          add(panel, BorderLayout.CENTER);

          setSize(200,100);

          setDefaultCloseOperation(EXIT_ON_CLOSE);

      }

      public static void main(String[] args) {

          new Test().setVisible(true);

      }

  }
  Kemudian run project, dan lihat hasilnya.
