Drawing a music stave

Question

Pleas help, i'm behind a deadline, whine whine.
Basically all these (all 3) class's worked seperatley but when i put them together the Note does not display on the stave
Write3001 - class accepts input from users (ie user inputs a chord name)
Stave Class - draws the five lines of a stave and sends the start co-ordinates (depending on the note) to the note class
note class - draws a note with the co-ordinates given to it:
source (this is justthe basic shell)
* user can input a chord name in an edit box
* and the chord is written on a stave diagram
//ie musical notation
* uses stavediagram class which calls appropriate
public class WriteChord3001 extends javax.swing.JFrame {
private JPanel staveDiagramPane;
public WriteChord3001() {
     ...private JTextField input;
//stave diagram pane*****************************
//displays appropriate stave diagram
staveDiagramPane = new JPanel(new BorderLayout());
staveDiagramPane.add(new StaveDiagram());
box.add(staveDiagramPane);
pack();
setVisible(true);
public void buildInput()
String chord;
staveDiagramPane.add(new StaveDiagram(chord));
pack();
kbPane.repaint();
public static void main (String args[]) {
new WriteChord3001 ().show ();
//inner class defining the StaveDiagram
class StaveDiagram extends JPanel
public StaveDiagram()
setLayout (new BorderLayout());
buildOutput();
public void paint(Graphics g)
//paints the stave lines
public void buildOutput()
     ///here's the problem part:
staveDiagramPane.add(new Note(x,y,notetype));
pack();
staveDiagramPane.repaint();
//inner class defining a note
class Note extends JPanel
public Note(int x,int y, String s)
initComponents ();
//set note type *****************************
          // ie. crotchet or quaver etc.
//***********drawing notes:
public void paint(Graphics g)
g.drawOval(x,y,size,size);
//=================================================
//end of note class
//=================================================
//end of StaveDiagram class
the end

Answer 1

Well, it never could work at all!!!
So you get a JFrame, put a JPanel (staveDiagramPane) on it, put another JPanel (staveDiagram) into it, and each note is ANOTHER JPanel the second JPanel is supposed to add on the first JPanel? It's mad!!!
First of all, you won't see anything just because this is not the way BorderLayout is supposed to work! You can't simply add a component (not specifying where you want to add it - i.e. BorderLayout.CENTER, i suppose...). Second, why don't you simply use one JComponent (call It StaveComponent) whose paint() method draws both the diagram and notes (you can represent them defining one class that ineriths from Object: a note is NOT a Component nor a JPanel!)?
Hope it helps...
