Okeydokey. This'll be longish, so bear with me.
TestGUIMainFrame
The main frame of the application, where the tabbed panes should be loading.
The place where I've assumed the tabbed panes should be loading is in this file, where I've written:
contentPane.add(mainScreen, BorderLayout.CENTER);
package test;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import test.TestGUITabbedPanes;
public class testGUIMainFrame extends JFrame {

// JDesktopPane contentPane;

/** Menu Bar */

/** Tool Bar */
/** Look for more icons for toolbar */
JToolBar toolBar = new JToolBar();
JButton openFileButton = new JButton();

ImageIcon helpButtonImage;
/** Status Bar */

/** Construct the frame */
public TestGUIMainFrame() {

TestGUITabbedPanes
This is the class where the tabbed panes are setup.
package test;
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
class TestGUITabbedPanes extends JPanel
{
JTabbedPane tabbedPane;
JPanel panel1;
JPanel panel2;
JPanel panel3;
public TestGUITabbedPanes()
{
// Create the tab pages
createPage1();
createPage2();
createPage3();
// Create a tabbed pane
tabbedPane = new JTabbedPane();
tabbedPane.addTab("Test Tab 1", panel1);
tabbedPane.addTab("Test Tab 2", panel2);
tabbedPane.addTab("Test Tab 3", panel3);
}
public void createPage1()
{
panel1 = new JPanel();
panel1.setLayout(null);
JLabel label1 = new JLabel("Username:");
label1.setBounds( 10, 15, 150, 20 );
panel1.add(label1);
JTextField field = new JTextField();
field.setBounds(10, 35, 150, 20);
panel1.add(field);
JLabel label2 = new JLabel( "Password:" );
label2.setBounds( 10, 60, 150, 20 );
panel1.add( label2 );
JPasswordField fieldPass = new JPasswordField();
fieldPass.setBounds( 10, 80, 150, 20 );
panel1.add( fieldPass );
}
public void createPage2()
{
panel2 = new JPanel();
panel2.setLayout( new BorderLayout() );
panel2.add( new JButton( "North" ), BorderLayout.NORTH );
panel2.add( new JButton( "South" ), BorderLayout.SOUTH );
panel2.add( new JButton( "East" ), BorderLayout.EAST );
panel2.add( new JButton( "West" ), BorderLayout.WEST );
panel2.add( new JButton( "Center" ), BorderLayout.CENTER );
}
public void createPage3()
{
panel3 = new JPanel();
panel3.setLayout( new GridLayout( 3, 2 ) );
panel3.add( new JLabel( "Field 1:" ) );
panel3.add( new TextArea() );
panel3.add( new JLabel( "Field 2:" ) );
panel3.add( new TextArea() );
panel3.add( new JLabel( "Field 3:" ) );
panel3.add( new TextArea() );
}
}
Phew! Sorry for the spam, but there it is. Any help, again, would be greatly appreciated. I'm sure I'm just being stupid.
