MouseEvent problem AWT Java

Question

I'm simply trying to I’m simply trying to draw a circle in the same location as mouse click, but I can’t get it to work. Here is the code:

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class LineApp
{
 public static void main ( String args[])
 {
 MainWindow mainWdw = new MainWindow();
 }
}
class MainWindow extends Frame
{
 private Point recPoint;
 private boolean mouseClick;
 MainWindow()
 {
 mouseClick = false;
 setBackground( Color.BLACK );
 setSize( 400,300 );
 setLocation( new Point( 300,300));
 addComponentListener(new ComponentCatcher());
 addWindowListener(new WindowCatcher());
 addMouseListener(new MouseCatcher());
 setVisible( true );
 }
 public void paint( Graphics gc )
 {
 gc.setColor(Color.ORANGE);
 if(mouseClick)
 {
 gc.setColor(Color.ORANGE);
 gc.fillOval(recPoint.x, recPoint.y, 30,30);
 }
 }
 class WindowCatcher extends WindowAdapter
 {
 public void windowClosing( WindowEvent evt)
 {
 evt.getWindow().dispose();
 System.exit (0);
 }
 }
 class ComponentCatcher extends ComponentAdapter
 {
 public void componentResized (ComponentEvent evt)
 {
 repaint();
 }
 }
 class MouseCatcher extends MouseAdapter
 {
 public void mousedPressed ( MouseEvent evt)
 {
 Point mousePt = new Point();
 mousePt = evt.getPoint();
 recPoint = new Point(mousePt.x,mousePt.y);
 mouseClick = true;
 repaint();
 }
}

}

• Adamski: What specifically is not working about your code? Is the circle appearing at all?

Answer 1

The method in MouseAdapter is called mousePressed, not mousedPressed.

The @Override-annotation can help you to avoid errors like that. If you would have used

 @Override
 public void mousedPressed ( MouseEvent evt)
 {
 ...

your code would not have compiled.
