Belajar lagi tentang Event Handling dari dasar.

Berikut ini code untuk handling mouse wheel event.

Nama file MouseWheelDemo.java

import javax.swing.*;
public class MouseWheelDemo extends JFrame {
MouseWheelEventDemo event = new MouseWheelEventDemo();

public MouseWheelDemo(){
setSize(500,500);
JTextArea mainJTextArea = new JTextArea();
mainJTextArea.addMouseWheelListener(event);
add(mainJTextArea);
setVisible(true);

}
public void setFrame(){

setVisible(true);
}

public static void main(String[] args){

MouseWheelDemo x = new MouseWheelDemo();

}

}

Nama file MouseWheelEventDemo.java

import java.awt.event.MouseWheelListener;

public class MouseWheelEventDemo implements MouseWheelListener{

public void mouseWheelMoved(java.awt.event.MouseWheelEvent event) {
System.out.println("MouseWheelListenerDemo.mouseWheelMoved");

if (event.getWheelRotation() < 0) {
System.out.println("Rotated Up " + event.getWheelRotation());
} else {
System.out.println("Rotated Down " + event.getWheelRotation());
}

}

}
