Graphics

[Joe2003]

Hey

Im trying to add some graphics to an JFrame. I have already made a jframe with loads of panels that hold seperate content. Anyway I want to add a picture, eg this smile app I riped off the net :-

Code:

    public TestDraw()
    {        
        setLayout(new FlowLayout());            
        setTitle("Changing Face");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setSize(250,220);
        setLocation(300,300);
        getContentPane().setBackground(Color.yellow);
        setVisible(true);
    }
    
       
    public void paint(Graphics g)
    {
        super.paint(g);   
        g.setColor(Color.red);
        g.drawOval(85,75,75,75);   
        g.setColor(Color.blue);
        g.drawOval(100,95,10,10);  
        g.drawOval(135,95,10,10); 
       
        g.drawArc(102,115,40,25,0,-180); 
        g.drawString("Changing Face", 80,175);
    }

So the class holding the above functions must extend the JFrame, fair enough, but is it possible to add this kind of content to a JPanel? Main problem I have, is that the area im drawing "things" in is a 660 x 430 space within a rather crowded window, and the size of the image may vary (its mapping software) so I dont want to start drawing over other widgets?

any pointers?

thanks

This could be one of the way that you define your own JComponent for your graphics object.

Code:

public class SmilePanel extends JComponent {
	
	
	public void paint(Graphics g) {
		super.paint(g);
		g.setColor(Color.red);
		g.drawOval(85, 75, 75, 75);
		g.setColor(Color.blue);
		g.drawOval(100, 95, 10, 10);
		g.drawOval(135, 95, 10, 10);

		g.drawArc(102, 115, 40, 25, 0, -180);
		g.drawString("Changing Face", 80, 175);
	}
	
	@Override
	public Dimension getPreferredSize() {
		Dimension dimension = new Dimension(200,200); // Change to required size
		return dimension;
	}	
}
...
getContentPane().add(new SmilePanel());
