Java Swing GUI Invisible

Java Swing GUI Invisible - java

basically I have a very simple GUI, but for some reason when I run the code the JButtons only appear when I mouse over them, and the JTextField only appear if I click on them. How do I fix this so that they are visible when the program runs? Thanks.
Here is my code:
//JFrame + settings
JFrame frmFormSubmission = new JFrame();
frmFormSubmission.setSize(new Dimension(350, 165));
frmFormSubmission.setTitle("Form Submission - Client");
frmFormSubmission.setLocationRelativeTo(null);
frmFormSubmission.setVisible(true);
frmFormSubmission.setResizable(false);
frmFormSubmission.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
//JPanel
JPanel panel = new JPanel();
frmFormSubmission.getContentPane().add(panel, BorderLayout.CENTER);
panel.setLayout(null);
//JLabels
//Name
JLabel lblName = new JLabel("Name:");
lblName.setFont(new Font("Tahoma", Font.PLAIN, 14));
lblName.setBounds(46, 12, 40, 14);
panel.add(lblName);
//Address
JLabel lblAddress = new JLabel("Address:");
lblAddress.setFont(new Font("Tahoma", Font.PLAIN, 14));
lblAddress.setBounds(33, 37, 53, 14);
panel.add(lblAddress);
//Phone
JLabel lblPhone = new JLabel("Phone #:");
lblPhone.setFont(new Font("Tahoma", Font.PLAIN, 14));
lblPhone.setBounds(28, 62, 58, 14);
panel.add(lblPhone);
//Email
JLabel lblEmail = new JLabel("Email:");
lblEmail.setFont(new Font("Tahoma", Font.PLAIN, 14));
lblEmail.setBounds(46, 87, 36, 14);
panel.add(lblEmail);
//JTextFields
//Name
nameField = new JTextField();
nameField.setBounds(93, 11, 137, 20);
panel.add(nameField);
nameField.setColumns(10);
//Address
addressField = new JTextField();
addressField.setColumns(10);
addressField.setBounds(93, 36, 137, 20);
panel.add(addressField);
//Phone
phoneField = new JTextField();
phoneField.setColumns(10);
phoneField.setBounds(93, 61, 137, 20);
panel.add(phoneField);
//Email
emailField = new JTextField();
emailField.setColumns(10);
emailField.setBounds(93, 86, 137, 20);
panel.add(emailField);
//JButtons
//Submit
JButton btnSubmit = new JButton("Submit");
btnSubmit.setBounds(240, 10, 89, 23);
panel.add(btnSubmit);
//Cancel
JButton btnCancel = new JButton("Cancel");
btnCancel.setBounds(240, 44, 89, 23);
panel.add(btnCancel);
//Flush
JButton btnFlush = new JButton("Flush");
btnFlush.setBounds(240, 76, 89, 23);
panel.add(btnFlush);
//Checkbox
JCheckBox chckbxPromotions = new JCheckBox("Email me with new and promotions!");
chckbxPromotions.setBounds(25, 108, 205, 23);
panel.add(chckbxPromotions);
Any help is very much appreciated!

Call frmFormSubmission.setVisible(true); as the last thing you do. setVisible will layout your components so they can be properly drawn. If you add components without laying them out, then you'll have graphical issues.
For more information on what that means, check out the documentation on the validate method.

Also, try
frmFormSubmission.invalidate();
frmFormSubmission.validate();
frmFormSubmission.repaint();
If this still does not work, you can try this:
SwingUtilities.updateComponentTreeUI(frmFormSubmission);

I was hoping to make the checkboxes able to be scrolled through.`

See the below runnable code to see one way this can be done using a JDialog for a window and Layout managers. Be sure to read the comments in code. You should be able to adapt the concept to your specific application:

I couldnt set location of components in Java for usinf JFrame and contentPane?

I want to create a simple profile information page with JFrame and contentPane. I added all the components correctly. But I cant set their location. How can i set it? I used setBoundary() method bur it doesnt work.
My Anket.java class is:

The program doesnt have any error. How can i fix this problem?
My output screen is:

You should replace
Container contentPane = frame.getContentPane();
contentPane.setBackground(Color.GRAY);
with
JPanel contentPane = new JPanel(null); // The null is important
contentPane.setBackground(Color.GRAY);
frame.setContentPane(contentPane); // each time you change the content pane you need to revalidate the jframe (frame.setVisible(true) also revalidate the jframe so in this case it is not needed to revalidate the jframe)

Why does this program's interface disappear to the right?

I'm working on a group project with my friends for a school assignment. Unfortunately, one of my group members made this program which was much worse before (I tried to fix most of the main issues). Only problem now is, the program doesn't load all of the text on the right, instead leaving ellipses (...).
I've tried modifying and removing setBounds, setSize, and contentPane, yet all those proved ineffective. I'm fairly new to Java all round, so please do go easy on my inexperience.

Instead of "WE DO nothin..." and "Wel..." (at the top right), it should display "WE DO nothing at ALL!" (Also, do let me know if the code doesn't work.)

Java Swing open existing form

I'm trying to call a method that opens a new existing frame, but all I get is an empty frame without content.
This is the code that calls the function when a button is preesed:
JButton btnPersonalInfo = new JButton("Personal Info");
btnPersonalInfo.setBounds(10, 5, 120, 23);
btnPersonalInfo.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
JFrame PersonalInfo = new JFrame("Personal Info");
PersonalInfo content = new PersonalInfo();
PersonalInfo.setContentPane(content);
PersonalInfo.setSize(700,700);
PersonalInfo.setLocation(100,15);
PersonalInfo.setDefaultCloseOperation( JFrame.HIDE_ON_CLOSE );
PersonalInfo.setResizable(false);
PersonalInfo.setVisible(true);
}
});
panel_1.add(btnPersonalInfo);
This is how I initialize the PersonalInfo function:
public PersonalInfo() {
initialize();
}
/**
* Initialize the contents of the frame.
*/
private void initialize() {
frame = new JFrame();
frame.setBounds(100, 100, 450, 300);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
JPanel panel = new JPanel();
frame.getContentPane().add(panel, BorderLayout.CENTER);
panel.setLayout(null);
JLabel lblPersonalInfo = new JLabel("Personal Information");
lblPersonalInfo.setFont(new Font("Arial", Font.BOLD, 16));
lblPersonalInfo.setBounds(110, 11, 185, 14);
panel.add(lblPersonalInfo);
JLabel lblFullName = new JLabel("Full Name");
lblFullName.setBounds(10, 36, 58, 14);
panel.add(lblFullName);
JLabel lblNationality = new JLabel("Nationality");
lblNationality.setBounds(10, 61, 78, 14);
panel.add(lblNationality);
JLabel lblDateBirth = new JLabel("Date of Birth");
lblDateBirth.setBounds(10, 86, 78, 14);
panel.add(lblDateBirth);
JLabel lblGender = new JLabel("Gender");
lblGender.setBounds(10, 111, 46, 14);
panel.add(lblGender);
JLabel lblAddress = new JLabel("Address");
lblAddress.setBounds(10, 164, 58, 14);
panel.add(lblAddress);
JLabel lblMobile = new JLabel("Mobile");
lblMobile.setBounds(10, 189, 46, 14);
panel.add(lblMobile);
JLabel lblEmail = new JLabel("E-mail");
lblEmail.setBounds(10, 214, 46, 14);
panel.add(lblEmail);
JRadioButton rdbtnM_2 = new JRadioButton("M");
rdbtnM_2.setBounds(74, 133, 109, 23);
panel.add(rdbtnM_2);
JRadioButton rdbtnF = new JRadioButton("F");
rdbtnF.setBounds(74, 107, 109, 23);
panel.add(rdbtnF);
}
}
Basically I'm expecting to view the frame from the PersonalInfo method when I press the btnPersonalInfo button and right now I only get an empty frame.
Thank you and sorry if this is a duplicate, but it's my first question here.

Remove frame = new JFrame(); from your initialize()
Simply:
JPanel panel = new JPanel();
add(panel, BorderLayout.CENTER);//It will be added to the ContentPane by default.
panel.setLayout(null);
...
Then when calling, remove the following block:
JFrame PersonalInfo = new JFrame("Personal Info");
PersonalInfo content = new PersonalInfo();
PersonalInfo.setContentPane(content);
Replace it by:
PersonalInfo personalInfo = new PersonalInfo();
personalInfo.setSize(700,700);
personalInfo.setLocation(100,15);
....
So this should be your method call:
public void actionPerformed(ActionEvent e) {
PersonalInfo personalInfo = new PersonalInfo();
personalInfo.setSize(700,700);
personalInfo.setLocation(100,15);
personalInfo.setDefaultCloseOperation( JFrame.HIDE_ON_CLOSE );
personalInfo.setResizable(false);
personalInfo.setVisible(true);
}
And this should be your Class:
public class PersonalInfo extends JFrame
{
public PersonalInfo() {
initialize();
}
/**
* Initialize the contents of the frame.
*/
private void initialize() {
JPanel panel = new JPanel();
add(panel, BorderLayout.CENTER);
panel.setLayout(null);
JLabel lblPersonalInfo = new JLabel("Personal Information");
lblPersonalInfo.setFont(new Font("Arial", Font.BOLD, 16));
lblPersonalInfo.setBounds(110, 11, 185, 14);
panel.add(lblPersonalInfo);
JLabel lblFullName = new JLabel("Full Name");
lblFullName.setBounds(10, 36, 58, 14);
panel.add(lblFullName);
JLabel lblNationality = new JLabel("Nationality");
lblNationality.setBounds(10, 61, 78, 14);
panel.add(lblNationality);
JLabel lblDateBirth = new JLabel("Date of Birth");
lblDateBirth.setBounds(10, 86, 78, 14);
panel.add(lblDateBirth);
JLabel lblGender = new JLabel("Gender");
lblGender.setBounds(10, 111, 46, 14);
panel.add(lblGender);
JLabel lblAddress = new JLabel("Address");
lblAddress.setBounds(10, 164, 58, 14);
panel.add(lblAddress);
JLabel lblMobile = new JLabel("Mobile");
lblMobile.setBounds(10, 189, 46, 14);
panel.add(lblMobile);
JLabel lblEmail = new JLabel("E-mail");
lblEmail.setBounds(10, 214, 46, 14);
panel.add(lblEmail);
JRadioButton rdbtnM_2 = new JRadioButton("M");
rdbtnM_2.setBounds(74, 133, 109, 23);
panel.add(rdbtnM_2);
JRadioButton rdbtnF = new JRadioButton("F");
rdbtnF.setBounds(74, 107, 109, 23);
panel.add(rdbtnF);
}
}

WindowBuilder Source Code Layout and Database Implementation

Hi I am a newbie java programmer, I am currently creating a java gui application using WindowBuilder within eclipse.
I have the layout that I like however, the source code is all in one class, and I can't seem to navigate through the panels correctly.
A link to the image for how the layout of panels is in WindowBuilder - http://postimg.org/image/xmnm9ilm1/
I was wondering how can I best layout the code, and how best to navigate through the program.
Bear in mind I don't know many techical terms.
Also what is the best way to implement a microsoft access backend database that can be editied within the program for login usernames, passwords and adding and removing items? I have a seperate database class at the moment.
Thank You
