I created a window using the design panel in JFrame, it didn't have any problem. But suddenly, When I try to edit my window using design, nothing shows up. I can't even run that window, but if i start running it from the previous page, it shows up (I use the setVisible method to do this). You can see my code below:
import java.awt.EventQueue;
public class seat extends JFrame {

public seat() {
// TODO Auto-generated constructor stub
}
}
Within the public static void main only the empty constructor is called. You have to call constructor with the parameters which contains the code which builds the GUI.
Instead of calling the standard constructor with
seat frame = new seat();
you have to call it with
seat frame = new seat("from", "to", "time", "date");

I have been trying this for hours. I want to change each of the JButton components to image buttons (They were radio buttons that's why the variable names don't make sense). The for loop inside is just displaying all the images under the button's. Each image is called Option1, Option2, etc. So what I have been trying to do is get rid of the for loop and just have 10 buttons with images on them that you can click.
If someone could help me figure that out that would be great. All I've been able to do is have the button created with an image but the button appears on a completely different window.

I have written some code when one of the option in radio button is clicked
it should display one jlabel and jtext field. And when other option in the radio button is clicked it should hide the previous shown jlabel and jtext field and display new jlabel and jtext field.
In the output when I click on one of the radio button it is displaying nothing unless and until I maximize my Window. After geting my jlabel and jtextfield If I click on other radio button the jlabel and jtextfield is hidden but Im not able to see new jlabel and jtextfield for that radiobutton.

Insteed of adding and removing components, simply add all and hide/show them on radiobox selection like this:
panel_1.add(jlblEmpSal);
panel_1.add(jtxtSal);
panel_1.add(jlblEmpHour);
panel_1.add(jtxtHour_Pay);
panel_1.add(jlblEmpWork);
panel_1.add(jtxtHour_Worked);
ActionListener myAction = new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
jlblEmpHour.setVisible(jrdbtnContract.isSelected());
jtxtHour_Pay.setVisible(jrdbtnContract.isSelected());
jtxtHour_Worked.setVisible(jrdbtnContract.isSelected());
jlblEmpWork.setVisible(jrdbtnContract.isSelected());
jlblEmpSal.setVisible(jrdbuttonFullTime.isSelected());
jtxtSal.setVisible(jrdbuttonFullTime.isSelected());
}
};
myAction.actionPerformed(null); // to initialize labels first
jrdbuttonFullTime.addActionListener(myAction); // add actionlisteners
jrdbtnContract.addActionListener(myAction);// add actionlisteners
As you can see, you dont even need 2 separate action listeners as one but shared instance is just enough.
So the complete app will look like this:

Your radio buttons start off both unchecked, so you see no salary detail initially. When you click one or the other, the corresponding details appear.
In which case(which radiobutton checked ?) you want to show which controls?
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);
}
}
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);

This is the sample concrete builder pattern that will be used as the View. Is it really appropriate since it is the builder but not the view? I'm still a newbie with regards to design patterns. sorry for that. Thanks anyway!
I'd say that a Builder is a perfectly good kind of thing to use in the role of a view.
It's not really a good question to be asking yourself though. Design patterns exist to help you find solutions to specific problems and to discuss them with others using a common vocabulary. If the code follows good OOP principles such as coherence, consistency, etc., and is easy to understand and maintain, then it doesn't really matter whether your code strictly meets the definition of some particular named design pattern or other.
