I am trying to update the text of a Jlabel from another class. I tried using the setText method, which results in the program compiling fine, and running, however when I press the button nothing happens.
Here is the code from my Menu.class, where the Jlabel resides.
public class Menu extends JFrame {
private JPanel contentPane;
private JLabel lblOthello;
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
public void run() {
Menu frame = new Menu();
frame.setVisible(true);
}
});
}
public Menu() {
//Sets program icon
ImageIcon img = new ImageIcon("icon.png");
//Creates the frame
setForeground(Color.RED);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
setBounds(100, 100, 384, 475);
contentPane = new JPanel();
contentPane.setBackground(Color.BLACK);
contentPane.setBorder(new EmptyBorder(5, 5, 5, 5));
setContentPane(contentPane);
contentPane.setLayout(null);
lblOthello = new JLabel("Othello");
lblOthello.setForeground(Color.YELLOW);
lblOthello.setFont(new Font("Franklin Gothic Medium Cond", Font.BOLD, 33));
lblOthello.setHorizontalAlignment(SwingConstants.CENTER);
lblOthello.setBounds(0, 0, 366, 59);
contentPane.add(lblOthello);
JButton btnNewButton = new JButton("New Singleplayer Game");
btnNewButton.setForeground(Color.BLACK);
btnNewButton.setBackground(UIManager.getColor("Button.background"));
btnNewButton.setBounds(10, 72, 344, 45);
btnNewButton.addActionListener(new ButtonListener());
contentPane.add(btnNewButton);
JButton btnNewMultiplayerGame = new JButton("New Dualplayer Game");
btnNewMultiplayerGame.setBounds(10, 130, 344, 45);
btnNewMultiplayerGame.addActionListener(new ButtonListener());
contentPane.add(btnNewMultiplayerGame);
JSeparator separator = new JSeparator();
separator.setBounds(0, 57, 366, 2);
contentPane.add(separator);
JButton btnNewNetworkGame = new JButton("New Network Game");
btnNewNetworkGame.setBounds(10, 188, 344, 45);
btnNewNetworkGame.addActionListener(new ButtonListener());
contentPane.add(btnNewNetworkGame);
JButton btnAbout = new JButton("AI vs AI Game");
btnAbout.setBounds(10, 246, 344, 45);
btnAbout.addActionListener(new ButtonListener());
contentPane.add(btnAbout);
JButton btnNewButton_1 = new JButton("QUIT");
btnNewButton_1.setBounds(10, 446, 344, 25);
btnNewButton_1.addActionListener(new ButtonListener());
contentPane.add(btnNewButton_1);
JLabel lblNewLabel = new JLabel("New label");
lblNewLabel.setIcon(new ImageIcon("C:\\Users\\User\\workspace\\Othello\\src\\Othello.jpg"));
lblNewLabel.setBounds(0, -36, 366, 507);
contentPane.add(lblNewLabel);
JButton button = new JButton("QUIT");
button.setBounds(10, 390, 344, 25);
button.addActionListener(new ButtonListener());
contentPane.add(button);
JSeparator separator_1 = new JSeparator();
separator_1.setBounds(0, 375, 366, 2);
contentPane.add(separator_1);
}
public void setText(String text) {
lblOthello.setText(text);
System.out.println("executed");
contentPane.validate();
contentPane.repaint();
}
}
And here is the part of the code that executes the settext method from my buttonlistener class
case PLAYER_VS_AI:
Menu men = new Menu();
men.setText("Now");
men.revalidate();
men.repaint();
break;
Can anyone tell me why this doesn't work?
You are creating a new Menu object whenever the button is pressed instead of modifying the already existing Menu object.

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:
import java.awt.*;
import javax.swing.*;
public class Anket {

lblNewLabel_4.setBounds(10, 21, 100, 85);
frame.getContentPane().add(lblNewLabel_4);
frame.setLayout(new FlowLayout());
frame.setVisible(true);
}
}
The program doesnt have any error. How can i fix this problem?
My output screen is:
output
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)
I'm trying to navigate with buttons in Java Swing.
I want to go to another existing frame when i click on a button.
I will attach first the Menu Panel:

l2 = new JLabel("This Program Made By Ghetto K");
l1.setForeground(Color.RED);
l1.setFont(new Font("Arial", Font.BOLD, 28));
l2.setForeground(Color.RED);
l2.setFont(new Font("Arial", Font.ITALIC,22));
btn1 = new JButton("Add Child");
btn2 = new JButton("Add Worker");
btn3 = new JButton("Add Class");

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();
}
}
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.
enter code here

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'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());
