FORM.SHOWDIALOG() IN JAVA

Have you wondered how to show a panel(form) as a dialog in java applications as done in .NET applications by using the form.showDialog() method?  For example, when a user selects “Add New” from a Customer combobox, the customer panel shows as a dialog for a new entry before the user can continue. If you have been searching for this, here is your stop.

We will be making use of one JDialog, and your FORMS(JPanels in this sense).

To implement this add a JDialog to your application. Declare a variable contentPane and add the constructor like the one specified below.

private Container contentPane = null;

public popupsjdialog(java.awt.Frame parent, JPanel panel, boolean modal) {
//super(parent, modal);
contentPane = this.getContentPane();
initComponents();
this.setSize(panel.getSize().width + 30, panel.getSize().width + 50);
panel.setLocation(10, 30);
contentPane.add(panel);
repaint();
this.setLocationRelativeTo(null);

}

Your are now done. Now to show any JPanel as a dialog add the following code to your event.

helpdetailpanel hd = new helpdetailpanel(helpContent);
hd.setSize(700, 700);
popupsjdialog d = new popupsjdialog(null, hd, true);
d.setVisible(true);

Helpdetailpanel is a Jpanel (form) you want to show as a dialog and the popupsjdialog is an instance of the Jdialog we created its constructot above.

Cheers !!!!!!!!!!!!!!!!!
