Answer 1

Creating a new Form with Scroll Bars using NetBeans GUI Builder:

• In the NetBeans Projects panel select the Package within the Project you want to create a JFrame form in;
• Right-Click on this package name and from the pop-up menus select New JFrame Form . A new JFrame form will be displayed within the GUI Builder of NetBeans;
• Size this form to what you want and apply the properties you want like Title, DefaultCloseOperation, AlwaysOnTop, Generate Center, etc) in the Properties Pane of the IDE;
• In the Pallet Pane of the IDE select Scroll Pane (JScrollPane) from the Swing Containers section and drag & drop it into the new JFrame window. Size the Scroll Pane component to be the full size of the JFrame Form;
• Again, in the Pallet Pane of the IDE select Panel (JPanel) from the Swing Containers section and drag & drop it into the new Scroll Pane component. The JPanel should automatically size up to the size of the Scroll Pane;
• Now drag & drop all the Swing components you want on your form into this JPanel . Enlarge the JFrame form if you have to to get all the components in then resize your form to what you want when done;
• You now have a JFrame window with a Scroll Pane.

Creating a new JFrame form with Scroll Bars and displaying an existing JFrame form within that Scroll Pane using NetBeans GUI Builder and a little bit of code:

• In the NetBeans Projects panel select the Package within the Project you want to create a JFrame form in;

• Right-Click on this package name and from the pop-up menus select New JFrame Form . A new JFrame form will be displayed within the GUI Builder of NetBeans;

• Size this form to what you want and apply the properties you want like Title, DefaultCloseOperation, AlwaysOnTop, Generate Center, etc) in the Properties Pane of the IDE;

• In the Pallet Pane of the IDE select Scroll Pane (JScrollPane) from the Swing Containers section and drag & drop it into the new JFrame window. Size the Scroll Pane component to be the full size of the JFrame Form. Keep the auto-assigned variable name which should be jScrollPane1 ;

• Switch to source code by selecting the Source tab in the IDE and navigate to the class constructor;

• Directly after the initComponents(); method call, make a call to the new private method named: moreInitialization() . This new method would look something like this:

   private void moreInitialization() { /* Instantiate the form you want to display within the new form with scroll bars, for example, if the Form class you want to view within Scroll-Bars is named 'MainForm' then... */ MainForm mf = new MainForm(); jScrollPane1.setViewportView(mf.getContentPane()); setSize(mf.getPreferredSize().width + 20, mf.getPreferredSize().height + 20); setLocationRelativeTo(null); }

• Display the new Scroll-Bar Form from the main() method with:

   java.awt.EventQueue.invokeLater(new Runnable() { @Override public void run() { new jFrame1.setVisible(true); } });

• Resize the form to see and use the Scroll Bars.
