How do I make a rectangle move in an image?
- by alicedimarco
Basically I have an image loaded, and when I click a portion of the image, a rectangle (with no fill) shows up. If I click another part of the image again, that rectangle will show up once more. With each click, the same rectangle should appear.
So far I have this code, now I don't know how to make the image appear. My image from my file directory. I have already made the code to get the image from my file directory.
import java.awt.Color;
import java.awt.Graphics;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;
import javax.swing.JFrame;
import javax.swing.JOptionPane;
import javax.swing.JPanel;
public class MP2 extends JPanel implements MouseListener{
JFrame frame;
JPanel panel;
int x = 0;
int y = 0;
String input;
public MP2(){
}
public static void main(String[] args){
JFrame frame = new JFrame();
MP2 panel = new MP2();
panel.addMouseListener(panel);
frame.add(panel);
frame.setSize(200,200);
frame.setVisible(true);
}
public void mouseClicked(MouseEvent event) {
// TODO Auto-generated method stub
this.x = event.getX();
this.y = event.getY();
this.repaint();
input = JOptionPane.showInputDialog("Something pops out");
System.out.println(input);
}
public void mouseEntered(MouseEvent arg0) {
// TODO Auto-generated method stub
}
public void mouseExited(MouseEvent arg0) {
// TODO Auto-generated method stub
}
public void mousePressed(MouseEvent arg0) {
// TODO Auto-generated method stub
}
public void mouseReleased(MouseEvent arg0) {
// TODO Auto-generated method stub
}
public void paintComponent(Graphics g){
super.paintComponent(g);
// this.setBackground(Color.white); *Sets the bg color of the panel
g.setColor(new Color(255,0,0));
g.drawRect(x, y, 100, 100);
}
}
