Contoh :
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.
