I have my ProfileInput class to store a JTextField input from a Dialog box. Then I transfer that to the setter and getter methods. From there I am calling the setter and getter methods in my AppFrame class.
The the problem that I am having is when I want the input to be displayed as a JLabel on the GUI nothing is showing up. I have no errors that are displayed when I run the code either. Any ideas as to what I have done wrong.
Please note that I am new to Java and am trying to learn. Any ideas/help to improve anything is also great.

You've got several problems with the above code, but most important, you're using a modeless dialog when you absolutely need to use a modal one. Since it is modeless, program flow in the calling code does not halt when the dialog is made visible, and so you're calling getFirstName() on the dialog immediately after it is opened, before it has been closed, and well before the user has had a chance to input any information whatsoever. A modal dialog on the other hand will freeze program flow in the calling code, and program flow will not resume until the dialog is no longer visible.
Problems and suggestions:
First and foremost, make sure the dialog window is a modal dialog.
But even before this, don't use Dialog, Panel and other AWT component classes, but rather use Swing classes -- JDialog, JPanel, etc.
You can set the JDialog to be modal with either the proper constructor, passing in ModalityType.APPLICATION_MODAL as a parameter within the appropriate constructor (see the API), or you can set it via a method.
Either way, make sure that it's set before setting the dialog visible.
Do this, and when you query the state of the dialog, you can be assured that the user has at least had a chance to interact with the dialog before you try to extract information from it.
Be sure to query the dialog and assign the results after setting it visible.
Edit, I see now that you're calling String firstNameTest = profileInput.getFirstName(); even before setting the dialog visible, as if the firstNameTest String, which is obviously null at this stage, will magically update once the dialog has been visualized and dealt with, but sorry, there's no magic in Java, and fields will not update by themselves. Again, do not set the firstNameTest field at that point, but rather only after the dialog has been displayed and then dealt with.
Next we'll need to talk about null layouts and setBounds. You really don't want to go this route, trust me.
For example:
public class AppFrame extends JFrame {
private static final long serialVersionUID = 1L;
// !! the JLabel needs to be a field so it can be set in the ActionListener
private JLabel firstNameInputTest = new JLabel("");
private ProfileInput profileInput = null; //!! let this start out as null
// !! worthless code, get rid of
// String firstNameTest = profileInput.getFirstName();
public static void main(String[] args) {
// .... etc
And the ActionListener where we create/display the dialog:
newEntry.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
//!! create JDialog in a lazy fashion
if (profileInput == null) {
// create dialog, passing in the JFrame
profileInput = new ProfileInput(AppFrame.this);
}
profileInput.setVisible(true); // display the *modal* dialog
// program flow is frozen here until JDialog is no longer visible
// query dialog for its contents
String firstNameTxt = profileInput.getFirstName();
// and use in GUI
firstNameInputTest.setText(firstNameTxt);
}
});
We don't want to declare the JLabel within a method or constructor since in doing so, it will not be visible throughout the class. So...
private AppFrame() { // ??? private ???
// .....
// test to see if first name displays
// !! JLabel firstNameInputTest = new JLabel(firstNameTest); // No!!!
Finally, a very simple example JDialog to demonstrate what I'm discussing:
#SuppressWarnings("serial")
public class ProfileInput extends JDialog {
private JTextField firstNameField = new JTextField(10);
public ProfileInput(JFrame frame) {
// make it modal!
super(frame, "Profile Input", ModalityType.APPLICATION_MODAL);
JPanel panel = new JPanel();
panel.add(new JLabel("Enter First Name:"));
panel.add(firstNameField);
panel.add(new JButton(new SubmitAction("Submit", KeyEvent.VK_S)));
add(panel);
pack();
setLocationRelativeTo(frame);
}
public String getFirstName() {
return firstNameField.getText();
}
private class SubmitAction extends AbstractAction {
public SubmitAction(String name, int mnemonic) {
super(name);
putValue(MNEMONIC_KEY, mnemonic);
}
#Override
public void actionPerformed(ActionEvent e) {
ProfileInput.this.dispose();
}
}
}

A JFrame is the actual frame that sits on the screen. So what you want to do is derive your MenuPanel and AddWorkerPanel classes from JPanel, so that they can both sit inside of one frame. Then, in your main frame class, you can have a CardLayout holding both of your panels, and have a button that cycles through the cards on the card layout, using the next() method in the card layout instance that you have stored.
If you just want to close one JFrame and then open the other you should be avble by just simply doing this in the calling method of your button:
button.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
new AddWorkerPanel();
super.dispose();
}
}
Days ago i asked for help to put a JPanel on top of the other CardLayout panels, with the help of one of the users i achieved it using GlassPane, so thanks to him, but now i wanna close it whenever i click outside it(in other windows of the applications or components) because its stuck there until i click settings button, how can i achieve that? I have tried with focus lost and gained but that doesn't work with the panel so what am i supposed to do, here is my piece of code..

In this customized JDialog, close button is active/focused by default and I can switch to OK button using Tab.
At any moment if the buton is active then I can click it either using the space bar or the mouse, but if the button is not active, I can not click it by the mouse, it does not respond, I have to make it active first, and this is what I do not understand.
Thank you.
Getting a bit into GUIs and trying to make something simple. However, I seem to be getting stuck on just making a simple "Exit" button. I am using the WindowsBuilder plugin for Eclipse to help me.

That's the whole initialize class for now. But if you would note near the bottom I have an event for the Exit button to where if you click on it the program should close. Except, when I click on the button nothing happens. Trying out other events like that in the fileBtn that works great. So what am I doing wrong?
Don't use mouseListeners, use ActionListeners.

Now as for the reason behind this, you were trying to use MouseListeners, while MouseListeners are good, you need to GET THE SOURCE of what you are listening to. Simply adding a listener will now do anything like it would if it was an ActionListener, part of the reason why I chose to use one. Also, tip for you, using ActionListeners listen for an Action done by the object it is attached to, MouseListeners listen to your and everything it does, whether or not it even has anything to do with your program. In the future, when using listeners, ensure that they listen only to what is absolutely necessary to your program. If you don't need to know the position of the mouse, don't follow it.
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
Typically this is how you would capture the exit event.
For your custom Exit button, instead of a MouseListener, try just a plain 'ol ActionListener
Any event on the button will then be captured, and your code gracefully exited.
i've added a title to my Jframe, and now its blocked everything else, what have I done??

If you are not using a LayoutManager on purpose (and it looks that way) make sure that you set a location and a size for your component.
pTitle.setLocation(100, 100);
pTitle.setSize(100, 100);
But you should rather remove this line
panel.setLayout(null);
and replace it with something like this:
panel.setLayout(new BorderLayout());
Also, don’t forget to add your pTitle to panel.
Add the label to the panel, don't create a new Panel for it
lblTitle = new JLabel("Bournemouth University Address Book");
lblTitle.setBounds(100, 0, 400, 20);
panel.add(lblTitle);
Try adding your JPanel pTitle to frame.getContentPane() or to the JPanel panel
Edit
Instead of
frame.add(pTitle);
do:
frame.getContentPanel().add(pTitle);
If this very quick fix doesn't help, stick with the answer you've already accepted.
You have to set a LayoutManager for your frame:
frame = new JFrame();
frame.getContentPane().setLayout(FooLayout());
