Hi I'm doing a program that firstly opens setting menu like in the picture
enter image description here
first I select the choices of the game I want from the jcombox and jdialog that open window to set the names .
this is the code of it :
public class SettingMenu extends JFrame {
boolean is3players = false, is4players = false;
BufferedImage settingImage;
String[] playersChoises = { "2", "3", "4" };
String[] sizeChoises = { "30", "50", "100" };
JComboBox comboBoxPlayers;
JComboBox comboBoxSizes;
static JButton startGame, writeNames;
public SettingMenu() {
JLabel howManyPlayersText = new JLabel("How many players ?");
comboBoxPlayers = new JComboBox(playersChoises);
if (comboBoxPlayers.getSelectedItem().equals("3")) {
is3players = true;
}
if (comboBoxPlayers.getSelectedItem().equals("4")) {
is3players = true;
is4players = true;
}
JLabel writeNamesText = new JLabel("Set names of playes");
writeNames = new JButton("set names");
JLabel sizeOfBoredText = new JLabel("What the size of the bored ?");
comboBoxSizes = new JComboBox(sizeChoises);
startGame = new JButton("Click to start the game!");
howManyPlayersText.setBounds(177, 200, 270, 100);
comboBoxPlayers.setBounds(230, 270, 100, 30);
writeNamesText.setBounds(230, 210, 380, 250);
writeNames.setBounds(240, 350, 100, 36);
sizeOfBoredText.setBounds(177, 376, 300, 100);
comboBoxSizes.setBounds(230, 450, 100, 30);
startGame.setBounds(200, 500, 200, 44);
add(howManyPlayersText);
add(comboBoxPlayers);
add(writeNamesText);
add(writeNames);
add(sizeOfBoredText);
add(comboBoxSizes);
add(startGame);
setVisible(true);
}
public static void main(String[] args) {
// open this class
new SettingMenu();
// when i click on startgame bottun open the class of the game
startGame.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
new LeadersAndSnake_Project201();
}
});
// when i click on writeNames bottun open the class of dialog
writeNames.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
new SetNames();
}
});
}
}
and this is Set Names class which open the set names window
enter image description here
class SetNames extends JDialog {
public JTextField setNamePlayer1, setNamePlayer2, setNamePlayer3, setNamePlayer4;
public SetNames() {
this.setSize(280, 151);
this.setLocationRelativeTo(null);
JLabel name1 = new JLabel("Set Player's 1 name : ");
setNamePlayer1 = new JTextField(7);
setNamePlayer1.setText("Player 1");
JLabel name2 = new JLabel("Set Player's 2 name : ");
setNamePlayer2 = new JTextField(7);
setNamePlayer2.setText("Player 2");
JPanel panelOfDialog_1 = new JPanel();
panelOfDialog_1.add(name1);
panelOfDialog_1.add(setNamePlayer1);
JPanel panelOfDialog_2 = new JPanel();
panelOfDialog_2.add(name2);
panelOfDialog_2.add(setNamePlayer2);
JPanel panelOfDialog_3 = new JPanel();
JButton okBotton = new JButton("OK");
add(okBotton);
okBotton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
setNamePlayer1 = new JTextField(setNamePlayer1.getText());
setNamePlayer2 = new JTextField(setNamePlayer2.getText());
setVisible(false);
}
});
panelOfDialog_3.add(okBotton);
add(panelOfDialog_1, BorderLayout.NORTH);
add(panelOfDialog_2, BorderLayout.CENTER);
add(panelOfDialog_3, BorderLayout.AFTER_LAST_LINE);
this.setVisible(true);
}
}
and this is the large class for the game but I just put the imprtant thinga here :
class LeadersAndSnake_Project201 extends JFrame implements ActionListener{
// Here I made an object of Setting Menu class for use the varible that it has
SettingMenu obj1 = new SettingMenu();
// Here I made an object of Set Names class to take the name inside the textfiled
SetNames obj2 = new SetNames();
public LeadersAndSnake_Project201() {
// -----------------left panel------------------------------
JPanel leftPanel = new JPanel();
GroupLayout groupLayout = new GroupLayout(leftPanel);
leftPanel.setLayout(groupLayout);
//---------------------------panel 1 for information player 1 -------------------------------------
JPanel panel1 = new JPanel();
ImageIcon imageMan1 = new ImageIcon("man1.png");
JLabel imageMan11 = new JLabel("", imageMan1, JLabel.CENTER);
JLabel player1text = new JLabel(obj2.setNamePlayer1.getText());
panel1.add(imageMan11);
panel1.add(player1text);
//---------------------------panel 2 for information player 2------------------------------------
JPanel panel2 = new JPanel();
ImageIcon imageMan2 = new ImageIcon("man2.png");
JLabel imageMan22 = new JLabel("", imageMan2, JLabel.CENTER);
JLabel player2text = new JLabel(obj2.setNamePlayer2.getText());
panel2.add(imageMan22);
panel2.add(player2text);
//---------------------------panel 3 for information player 3-------------------------------------
JPanel panel3 = new JPanel();
if(obj.is3 == true){
ImageIcon imageMan3 = new ImageIcon("man3.png");
JLabel imageMan33 = new JLabel("", imageMan3, JLabel.CENTER);
JLabel player3text = new JLabel("Player 3");
player2text.setFont(fontText);
panel3.add(imageMan33);
panel3.add(player3text);
}
}
}
Here on left panel are my problems
the jlable of player 1 and player 2 didn't chang even if I try to change them in the textfiled and the second problem is that the panel of player 3 didn't apper even if I select the chois "3" from the combox .
enter image description here
Try to call .pack() on the Frame after altering the elements.
EDIT
You have no code changing the labels. What you need is store the labels in a variable, like you did with other components, and in the ActionListener on on the okButton in SetNames(), instead of doing whatever you do to the TextFields there (which looks wrong), update the Label text.
So, for example
class SetNames extends JDialog {
[...]
public JButton okButton; // save okButton so others can add listeners
}
class LeadersAndSnake_Project201 extends JFrame implements ActionListener{
// Here I made an object of Set Names class to take the name inside the textfiled
SetNames obj2 = new SetNames();
public LeadersAndSnake_Project201() {
[...]
obj2.okButton.addActionListener(new ActionListener(){/*update labels*/});
}}

I am trying to write code for an application I'm making, I have my main frame with 6 buttons on them. When I push one of my buttons, it is meant to bring up a frame that has a tabbed layout set up.
I have the tabbed frame coded correctly and when I set each frame as visible they will appear to screen but they don't appear when the button is pushed.
I have action listeners connected to the buttons and the frames I want to connect with them as well as constructors but for some reason I can't get my code to work correctly.
I have added my driver and my first two forms I'm trying to connect to each other.

When i run it, i get this image. simpsonsFrame
this is what happens when i click the homer button i then have to max it to see a blank screen.homerFrame.
when i set the homerFrame to visible, it displays what i what to appear if the button was pushed.it shows homerFrame then it shows the simpsonFrame.homersetVisible true
So I have 2 questions, the following classes regarding the questions I will ask are supplemented below:
1) If I have multiple JCheckBoxes, how can I use an itemListener to know when a specific JCheckBox is selected.
(In the example below, I have 3 JCheckBoxes named petrol, Electric & diesel, if petrol is chosen how can I be aware of this, I want to do something like, if petrol is selected then remove some items from the JComboBox)
2) How can I make the progress bar increase or decrease when a JButton is clicked. In the code below I have a JProgressBar, when the user clicks drive I want the JProgressBar to decrease and when they select refuel I want the JProgressBar to increase. I sort of want the JProgressBar to represent the fuel Level of the car. How would I go about doing this?

Event handling class (2):
import java.awt.event.*;
public class CarEvent implements ActionListener, ItemListener {
public void actionPerformed(ActionEvent event){
String cmd = event.getActionCommand();
if(cmd.equals("Drive"));{
}
else if(cmd.equals("Park")){

else if(cmd.equals("Refuel")){
}
else if(cmd.equals("Reset")){
}
}
public void itemStateChanged(ItemEvent event){
Object identifier = event.getItem();
String item = identifier.toString();
if())
}
}
For the check box question the below code may help you.
Use the CarEvent class as a inner class to CarViewer.
In the CarViewer add the event to each control
public class CarViewer extends JFrame {
petrol.addItemListener (new CarEvent());
Electric.addItemListener (new CarEvent());
diesel.addItemListener (new CarEvent());
class CarEvent implements ActionListener, ItemListener {
#Override
public void actionPerformed(ActionEvent e) {
System.out.println(e.toString());
}
#Override
public void itemStateChanged(ItemEvent e) {
if (e.getItem().equals(petrol)) {
System.out.println("Petrol");
}
else if (e.getItem().equals(Electric)) {
System.out.println("Electric");
}
else if (e.getItem().equals(diesel)) {
System.out.println("Diesel");
}
}
} //CarEvent class
} //CarViewer class
If you want to use the CarEvent as a separate class then you need to pass the CarViewer class instance to this CarEvent class and access the check boxes (when the check boxes as public)
public class CarViewer extends JFrame {
petrol.addItemListener (new CarEvent(this));
//and so on ,,,,
}//CarViewer class
class CarEvent implements ActionListener, ItemListener {
CarViewer cv:
public CarEvent(CarViewer _object){
cv=_object;
}
#Override
public void actionPerformed(ActionEvent e) {
System.out.println(e.toString());
}
#Override
public void itemStateChanged(ItemEvent e) {
if (e.getItem().equals(cv.petrol)) {
System.out.println("Petrol");
}
else if (e.getItem().equals(cv.Electric)) {
System.out.println("Electric");
}
else if (e.getItem().equals(cv.diesel)) {
System.out.println("Diesel");
}
}
}//CarEvent class
I have a form , That when i click to save button, "Yes" String should display on my console!
(I use "Yes" String for test!)
But does not work when clicked.

return panel;
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
#Override
public void run() {
NewUserFrame1 newUserFrame1 = new NewUserFrame1();
}
});
}
#Override

if (e.getSource() == savebt) {
System.out.print("Yes");
}
}
}
You need to add an ActionListener to your button like so:
savebt.addActionListener(this);
or with an anonymous class, like so:
savebt.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
// your code.
}
});
Using anonymous classes (or inner classes) is better because you can't have more than one actionPerformed() method in a given class.
You need to tell the button to invoke the ActionListener:
savebt = new JButton("Save");
savebt.addActionListener(this);
Note if you intend to use the same method for the save and cancel buttons, you'll need to differentiate, perhaps by comparing the source of the ActionEvent against the two buttons.
I created an Address Book GUI, I just don't understand How to make the save and delete buttons to work, so when the user fills the text fields they can click save and it saves to the JList I have created and then they can also delete from it. How Do I Do this?

Buttons need Event Handlers to work. You have not added any Event Handlers to the Save and Delete buttons. You need to call the addActionListener on those buttons too.
I recommend anonymous inner classes:
mybutton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent event) {
//do whatever should happen when the button is clicked...
}
});
You need to addActionListener to the buttons btSave and btDelete.
You could create a anonymous class like this and perform your work there.
btSave.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent ae)
{
//Do you work for the button here
}
}
btDelete.addActionListener(new ActionListener()
{
public void actionPerformed(ActionEvent ae)
{
//Do you work for the button here
}
}
Edit:
I have an example to which you can refer to and accordingly make changes by understanding it. I got it from a professor at our institute.

If you only have one String to pass, add it to the constructor of your second JFrame:
public class SecondFrame extends JFrame {
public SecondFrame(String someValueFromFirstFrame) {
someTextField.setText(someValueFromFirstFrame);
}
}
and pass it when creating the second JFrame:
SecondFrame secondFrame = new SecondFrame(firstTextField.getText());
If there is more than one attribute to pass, consider putting them together in another class and pass the instance of this class. This saves you from changing the constructor every time you need to pass an additional variable.
Simply add some reference to the first frame in the second or pass the value you're interested in to the second frame before you display it.
As for the code example you requested:
public class SecondFrame extends JFrame {
private JFrame firstFrame;
public SecondFrame(JFrame firstFrame) {
this.firstFrame = firstFrame;
}
}
Now you can obtain everything there is to obtained from the firstFrame through the internal reference to it.
