problem with paint() in java
hi,
Presently I'm facing a new problem with the paint() in java. A call to an object of JPanel which has the paint() overridden does not actually implement the methods declared in paint().
Here's the code
Code:
package testzoom;
/**
*
* @author Lob Kush
*/
public class Zoom extends javax.swing.JFrame {
ImageContainer ic ;
/** Creates new form Zoom */
public Zoom() {
ic = new ImageContainer();
initComponents();
}
/** This method is called from within the constructor to
* initialize the form.
* WARNING: Do NOT modify this code. The content of this method is
* always regenerated by the Form Editor.
*/
@SuppressWarnings("unchecked")
// <editor-fold defaultstate="collapsed" desc="Generated Code">
private void initComponents() {
jPanel1 = new javax.swing.JPanel();
jPanel1.add(ic);
setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
setTitle("Zoom Test");
setBackground(new java.awt.Color(102, 102, 102));
jPanel1.setBackground(new java.awt.Color(255, 255, 204));
jPanel1.setBorder(javax.swing.BorderFactory.createMatteBorder(3, 3, 3, 3, new java.awt.Color(0, 0, 0)));
javax.swing.GroupLayout jPanel1Layout = new javax.swing.GroupLayout(jPanel1);
jPanel1.setLayout(jPanel1Layout);
jPanel1Layout.setHorizontalGroup(
jPanel1Layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
.addGap(0, 394, Short.MAX_VALUE)
);
jPanel1Layout.setVerticalGroup(
jPanel1Layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
.addGap(0, 272, Short.MAX_VALUE)
);
javax.swing.GroupLayout layout = new javax.swing.GroupLayout(getContentPane());
getContentPane().setLayout(layout);
layout.setHorizontalGroup(
layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
.addGroup(layout.createSequentialGroup()
.addContainerGap()

pack();
