Question

I’m working on a game and for the menus I’m using Canvases to draw the stuff for that menu.

For options and buttons I’m using Graphics on the canvas to draw a string. How to detect the mouse clicking the string?

options canvas:

import java.awt.Canvas;
import java.awt.Color;
import java.awt.Font;
import java.awt.Graphics;
import java.awt.event.MouseEvent;
import java.awt.event.MouseListener;

import javax.swing.JFrame;

public class OptionsScreen extends Canvas{

private static final long serialVersionUID = 1L;
private Mouse ms = new Mouse();
private int optionPos = 275;
private int volLev = 100;
private int screenX = 800;
private int screenY = 600;
private JFrame mainWindow;

public OptionsScreen(JFrame f)
{
    mainWindow = f;
}

public void paint(Graphics g) {
    g.setFont(new Font("JI-Pelter", Font.PLAIN, 24));
    g.setColor(Color.lightGray);

    //Draw strings
    //Music and Sound
    g.drawString("Music:", optionPos, 150); g.setColor(Color.yellow); g.drawString("On", optionPos + 100, 150); g.setColor(Color.white); g.drawString("Off", optionPos + 175, 150); g.setColor(Color.lightGray);
    g.drawString("Sound:", optionPos, 200); g.setColor(Color.yellow); g.drawString("On", optionPos + 100, 200); g.setColor(Color.white); g.drawString("Off", optionPos + 175, 200); g.setColor(Color.lightGray);
    g.drawString("Volume Level:", optionPos, 250); g.setColor(Color.white); g.drawString(volLev + "%", optionPos + 175, 250); g.setColor(Color.lightGray);
    //OpenGL Settings
    g.drawString("Advanced OpenGL:", optionPos, 300); g.setColor(Color.white); g.drawString("On", optionPos + 225, 300); g.setColor(Color.yellow); g.drawString("Off", optionPos + 300, 300); g.setColor(Color.lightGray);
    //Screen Settings
    g.drawString("Game Resolution:", optionPos, 350); g.setColor(Color.white); g.drawString(screenX + "x" + screenY, optionPos + 200, 350); g.setColor(Color.lightGray);
    this.addMouseListener(ms);
}
}

class Mouse implements MouseListener
{
@Override
public void mouseClicked(MouseEvent arg0) {
}

@Override
public void mouseEntered(MouseEvent arg0) {
    // TODO Auto-generated method stub
}

@Override
public void mouseExited(MouseEvent arg0) {
    // TODO Auto-generated method stub
}

@Override
public void mousePressed(MouseEvent arg0) {
    // TODO Auto-generated method stub
}

@Override
public void mouseReleased(MouseEvent arg0) {
    // TODO Auto-generated method stub
}
}

Just use a JLabel for the strings. Then you can add a MouseListener to the label.
