paint and repaint problem

Hallo,

I use Netbeans 6.5 and just to make simple, I made a GUI with Netbeans GUI Builder.
Say that I have made a JFrame with a JPanel. And I want to draw the graph in this JPanel.

In JPanel "ProfilPanelLinks" I have add this methode:

Code:

---

    private void gambar(Graphics g){
        ProfilPanelLinks.add(dataModel);
        dataModel.doDraw(g);
        ProfilPanelLinks.repaint();
    }

---

and the class for another is:

Code:

---

public class EvaluateDataModel {

    private EvaluateDrawing draw;

    protected EvaluateDataModel(){
        draw = new EvaluateDrawing();
    }
   
    public void doDraw(Graphics g)
    {
        draw.draw(g);
    }
}

---

Code:

---

public class EvaluateDrawing extends JPanel {

      public void draw(Graphics g)
    {
        Graphics2D g2d = (Graphics2D)g;
        super.paint(g2d);
        g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
        g2d.setStroke(new BasicStroke(1));
        g2d.setColor(Color.blue);
        g2d.drawLine(0, 0, 100, 100);
    }
}

---

There are 2 classes, yes, since this is just a cut from a long class. I need to paint at least 6 more graph from another ArrayList. But it won´t draw just a simple line.
Can anyone help me, how can I draw it with netbeans panel?

Thank you very much.

This is not really a NetBeans issue but a how to draw graphics in Swing issue, and I think that your best bet is to go to the Sun Java tutorials and check out the tutorials that cover this. There's a bit to learn, but it is all worthwhile.

Also, making a GUI with Netbeans GUI Builder makes things more complicated, not simpler.
