I am trying to display the drawing that I have posted. When my code runs and the user clicks Account, the panel only displays the buttons "OK" and "Cancel" (see screenshot). I have added three JTextAreas with a JLabel for each to the panel accountPanel but they don't display. My code is below.

JPanel uses FlowLayout by default which respects preferred sizes. The default width of the preferred size for the JTextArea's is 0 x 0. You need to give the JTextComponent's a preferred size for them to appear. Use the constructor that specifys rows & columns:
JTextArea card = new JTextArea(5, 10);
Don't forget to make the JTextArea scrollable by enclosing it in a JScrollPane:
accountPanel.add(new JScrollPane(card));

I am a new to Java, I met a problem. Once I click the Button, it never shows me another form, just disappear. You can see, I set the button ActionListener, but it only run the second line (close the current form).

I have multiple cancel, ok, and save buttons. When the user clicks one of these buttons, I need it to exit the JPanel, but not the whole program. I have tried multiple times and everything I do it exits the whole program. My code is below. I know there is a lot of stuff on my code and it can get confusing. Thanks in advance.

I have tried multiple times and everything I do it exits the whole program.
I don't see you code for closing the dialog so I can't guess what you might be doing wrong.
In your ActionListener you would invoke the dispose method on the dialog. The code would be something like:
JButton button = (JButton)event.getSource();
Window dialog = SwingUtilities.windowForComponent( button );
dialog.dispose();
A different approach might be to use a JOptionPane, then you don't need to code your own ActionListeners. You can easily add a panel to an option pane. The code below shows two approaches:
import java.awt.*;
import javax.swing.*;
public class OptionPanePanel
{
private static void createAndShowUI()
{
JFrame frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setLocationRelativeTo( null );
frame.setVisible( true );
// Build a custom panel
JPanel panel = new JPanel( new GridLayout(2, 2) );
panel.add( new JLabel("First Name") );
JTextField firstName = new JTextField(10);
// firstName.addAncestorListener( new RequestFocusListener(false) );
panel.add( firstName );
panel.add( new JLabel("Last Name") );
JTextField lastName = new JTextField(10);
panel.add( lastName );
int result = JOptionPane.showConfirmDialog(
null, // use your JFrame here
panel,
"Enter Name",
JOptionPane.YES_NO_OPTION,
JOptionPane.PLAIN_MESSAGE);
if(result == JOptionPane.YES_OPTION)
{
System.out.println(firstName.getText() + " : " + lastName.getText());
}
else
{
System.out.println("Canceled");
}
// Let Option Pane build the panel for you
Object[] msg = {"First Name:", firstName, "Last Name:", lastName};
result = JOptionPane.showConfirmDialog(
frame,
msg,
"Enter Name...",
JOptionPane.OK_CANCEL_OPTION,
JOptionPane.PLAIN_MESSAGE);
if (result == JOptionPane.YES_OPTION)
{
System.out.println(firstName.getText() + " : " + lastName.getText());
}
else
{
System.out.println("Canceled");
}
}
public static void main(String[] args)
{
EventQueue.invokeLater(new Runnable()
{
public void run()
{
createAndShowUI();
}
});
}
}
One problem with this approach is that focus will be on the OK button instead of the text field. To get around this you can use the RequestFocusListener found in Dialog Focus.
I have created a JPanel that has all the JRadioButtons on it that I need (it is called PortSettings). I also have a button, called port settings, when the user clicks the button, I need the JPanel to come up and display the radio buttons. I have tried to add the JPanel to the actionlistener but it doesn't work. My code is below. I have deleted all other ActionListener's from the other buttons except for the portsettings buttons. If this question is confusing I'm sorry. It's really hard to explain what I need to do. I have uploaded a drawing of what the panel will look like as well as a screenshot of my program.

I have tried to add a JFrame to the ActionListener then add the JPanel to the JFrame but nothing happens when I click the Port Settings button. Also, when I tried to add the JPanel to the JFrame it told me to put final in front of JPanel PortSettings = new JPanel();. Here is the code.

You´re on the right track, but you do not want to add your PortSettings panel to a new JFrame but somewhere on your previously built one, assigned to the local variable frame. So your action listener should rather be
portsettings.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
frame.add(PortSettings, BorderLayout.SOUTH);
frame.pack();
}
});
(This is assuming that you actually want to add it to the frame at that instant and not add it invisibly right from the start and turn it visible, like #Aleksei suggested.)
The error message about final is because you use PortSettings in an (anonymous) inner class - viz., the ActionListener. In my proposed modification the same goes for frame, so you need to adapt its declaration as well:
final JFrame frame = new JFrame();
The reason why is quite technical and beside the point right now: just do it.
If instead you want the panel to appear in a separate window, you need a JDialog for that, not a second JFrame:
portsettings.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
JDialog dialog = new JDialog(frame);
dialog.add(PortSettings);
dialog.pack();
dialog.setVisible(true);
}
});
Take a look at the JOptionPane class for a rich choice of ways to get more functionality out of dialogs.
Just add the action listener to all your buttons.
like this:
yourButton.addActionListener(this);
Do that for all the buttons.
Then take your TestPalication class's actionPreformed method and do whatever:
#Override
public void actionPerformed(ActionEvent arg0) {
((JRadioButton) arg0.getSource()).setTitle("Clicked!");
}
Your question was a little bit confusing but I hope this clarifies a little bit.
What's wrong with my code? The panel named 'leftPanel' is not showing up when i run the program whereas 'flightPanel
import javax.swing.*;
import java.awt.*;

mainFrame.setLayout(new BorderLayout());

}
}

timePanel.add(LDeparture);
timePanel.add(datePanel);
leftPanel.add(travelPanel);
leftPanel.add(timePanel);
mainFrame.add(leftPanel, BorderLayout.EAST);
}
}
Call mainFrame.setVisible(true); in last. I.e,
mainFrame.add(leftPanel, BorderLayout.EAST);
mainFrame.setVisible(true);
Here's what I get :
I'm putting together the basic layout for a contacts book, and I want to know how I can make the 3 test buttons span from edge to edge just as the arrow buttons do.
private static class ButtonHandler implements ActionListener {
public void actionPerformed(ActionEvent e) {
System.out.println("Code Placeholder");
}
}
public static void main(String[] args) {
//down button
ImageIcon downArrow = new ImageIcon("down.png");
JButton downButton = new JButton(downArrow);
ButtonHandler downListener = new ButtonHandler();
downButton.addActionListener(downListener);
//up button
ImageIcon upArrow = new ImageIcon("up.png");
JButton upButton = new JButton(upArrow);
ButtonHandler upListener = new ButtonHandler();
upButton.addActionListener(upListener);
//contacts
JButton test1Button = new JButton("Code Placeholder");
JButton test2Button = new JButton("Code Placeholder");
JButton test3Button = new JButton("Code Placeholder");
Box box = Box.createVerticalBox();
box.add(test1Button);
box.add(test2Button);
box.add(test3Button);
JPanel content = new JPanel();
content.setLayout(new BorderLayout());
content.add(box, BorderLayout.CENTER);
content.add(downButton, BorderLayout.SOUTH);
content.add(upButton, BorderLayout.NORTH);
JFrame window = new JFrame("Contacts");
window.setContentPane(content);
window.setSize(400, 600);
window.setLocation(100, 100);
window.setVisible(true);
}
Following up on #kloffy's suggestion:
package playground.tests;
import java.awt.GridLayout;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import junit.framework.TestCase;
public class ButtonTest extends TestCase {
public void testThreeButtons() throws Exception {
JPanel panel = new JPanel();
panel.setLayout(new GridLayout());
JButton button1 = new JButton("A");
JButton button2 = new JButton("B");
JButton button3 = new JButton("C");
panel.add(button1);
panel.add(button2);
panel.add(button3);
JFrame window = new JFrame("Contacts");
window.setContentPane(panel);
window.setSize(300, 600);
window.pack();
window.setVisible(true);
int width = button1.getWidth();
assertEquals(width, button2.getWidth());
assertEquals(width, button3.getWidth());
}
}
