How to add Mouse listener to an ImageIcon embedded in a JLabel?
I want to have a clickable icon (an ImageIcon object) inside a JLabel. How can I add a MouseListener or any ActionListener just to that Icon. Is there any other way to know if the icon has been clicked? I use the setIcon() method for the JLabel to set its icon.
Thanks.
您可以在容器中放置两个单独的JLabel，第一个使用文本，第二个使用图标，并将鼠标侦听器添加到图标JLabel。
这种方法非常黑，但为我工作。
JLabel.addMouseListener(new MouseAdapter(){
public void mousePressed(MouseEvent me){
try {
Robot robot = new Robot();
if(JLabel.getBounds().contains(me.getPoint()) && !robot.getPixelColor(me.getXOnScreen(),me.getYOnScreen()).equals(page.getBackground())){
//Do action here
}
} catch (AWTException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
});
you can use this code to solving your problem:
public class Test extends JFrame {
private JLabel label;
ImageIcon icon = new ImageIcon("example.gif");
public Test(){
label = new JLabel(icon);
label.addMouseListener(new MouseListener() {
public void mouseClicked(MouseEvent e) {
//for example
JOptionPane.showMessageDialog(null, "Hello");
}
public void mousePressed(MouseEvent e) {
}
public void mouseReleased(MouseEvent e) {
}
public void mouseEntered(MouseEvent e) {
}
public void mouseExited(MouseEvent e) {
}
});
}
}
