Hi All,

My code is as follows:

package practise;


public class ItemForm extends javax.swing.JInternalFrame {

/** Creates new form ItemForm */
public ItemForm() {
super("Item Form",true, true, true, true);
initComponents();
}


private void initComponents() {

setClosable(true);
setIconifiable(true);
setMaximizable(true);
setResizable(true);
setTitle("Item Form");
setMaximumSize(new java.awt.Dimension(800, 600));

javax.swing.GroupLayout layout = new javax.swing.GroupLayout(getContentPane());
getContentPane().setLayout(layout);
layout.setHorizontalGroup(
layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
.addGap(0, 394, Short.MAX_VALUE)
);
layout.setVerticalGroup(
layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
.addGap(0, 278, Short.MAX_VALUE)
);

pack();
}

But Minimize and iconifiable buttons are not displaying on the JIntenalFrame.

Neither I am able to resize the window. Please help.....

Thanks

worked fine for me.

perhaps posting a full working (non-working?) program might help resolve your problem

Code As Follows:

MainForm.java // It will display the main form with menu

package practise;


public class MainForm extends javax.swing.JFrame {

/** Creates new form MainForm */
public MainForm() {
initComponents();
}


private void initComponents() {

jContainer = new javax.swing.JDesktopPane();
jMenuBar1 = new javax.swing.JMenuBar();
jMenu1 = new javax.swing.JMenu();
mnuCustomer = new javax.swing.JMenuItem();
mnuItem = new javax.swing.JMenuItem();
jMenu2 = new javax.swing.JMenu();
jMenuItem3 = new javax.swing.JMenuItem();

setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);

jMenu1.setText("Forms");

mnuCustomer.setAccelerator(javax.swing.KeyStroke.getKeyStroke(java.awt.event.KeyEvent.VK_X, java.awt.event.InputEvent.ALT_MASK));
mnuCustomer.setText("Customer");
mnuCustomer.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent evt) {
mnuCustomerActionPerformed(evt);
}
});
jMenu1.add(mnuCustomer);

mnuItem.setAccelerator(javax.swing.KeyStroke.getKeyStroke(java.awt.event.KeyEvent.VK_I, java.awt.event.InputEvent.ALT_MASK));
mnuItem.setText("Item");
mnuItem.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent evt) {
mnuItemActionPerformed(evt);
}
});
jMenu1.add(mnuItem);

jMenuBar1.add(jMenu1);

jMenu2.setText("File");

jMenuItem3.setAccelerator(javax.swing.KeyStroke.getKeyStroke(java.awt.event.KeyEvent.VK_X, java.awt.event.InputEvent.ALT_MASK));
jMenuItem3.setText("Exit");
jMenuItem3.addActionListener(new java.awt.event.ActionListener() {
public void actionPerformed(java.awt.event.ActionEvent evt) {
jMenuItem3ActionPerformed(evt);
}
});
jMenu2.add(jMenuItem3);

jMenuBar1.add(jMenu2);

setJMenuBar(jMenuBar1);

javax.swing.GroupLayout layout = new javax.swing.GroupLayout(getContentPane());
getContentPane().setLayout(layout);
layout.setHorizontalGroup(
layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
.addComponent(jContainer, javax.swing.GroupLayout.DEFAULT_SIZE, 418, Short.MAX_VALUE)
);
layout.setVerticalGroup(
layout.createParallelGroup(javax.swing.GroupLayout.Alignment.LEADING)
.addGroup(layout.createSequentialGroup()
.addComponent(jContainer, javax.swing.GroupLayout.DEFAULT_SIZE, 289, Short.MAX_VALUE)
.addContainerGap())
);

pack();
}

private void mnuCustomerActionPerformed(java.awt.event.ActionEvent evt) {
CustomerView cv=new CustomerView();
jContainer.add(cv);
cv.setVisible(true);
}

private void jMenuItem3ActionPerformed(java.awt.event.ActionEvent evt) {
System.exit(0);
}

private void mnuItemActionPerformed(java.awt.event.ActionEvent evt) {
ItemForm iv=new ItemForm();
jContainer.add(iv);
iv.setVisible(true);
}

/**
* @param args the command line arguments
*/
public static void main(String args[]) {
java.awt.EventQueue.invokeLater(new Runnable() {
public void run() {
new MainForm().setVisible(true);
}
});
}

// Variables declaration - do not modify
private javax.swing.JDesktopPane jContainer;
private javax.swing.JMenu jMenu1;
private javax.swing.JMenu jMenu2;
private javax.swing.JMenuBar jMenuBar1;
private javax.swing.JMenuItem jMenuItem3;
private javax.swing.JMenuItem mnuCustomer;
private javax.swing.JMenuItem mnuItem;
// End of variables declaration

I am editing my question. Please go through my problem and give me a solution.

MainForm.java // This class will display the main window and it will act as MDI form






I am not getting the minimize or iconifiable button on the screen. Neither I am able to resize the window. Please help.

If you can give any other way to do the make MDI form in java. Then also i am fine with that.
Thanks

You still hadn't used code tags. I've added them for you this once, and you can see how much better it looks.

again, worked fine for me - clicking Forms/Item, JInternalFrame appeared, with all buttons (working).

perhaps an OS or version problem - I'm using java 1.6.0_15 on Vista Home Premium

in the code you posted there's no advantage in extending JInternalFrame (you may be adding code later),
so see if it makes any difference using a standard JInternalFrame
