I need to make GUI which saves the user's input using a linked list and let him/her "browse" through the saved data. I made a simpler version of the code which I included below. My problem is how to "update" the buttons in the browse card after the user entered and saved a text.
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class sampleDemo extends JPanel {
NodeSample newNode = new NodeSample();
SampleSave s = new SampleSave();
public static final String CARD_ADD = "Card Add";
public static final String CARD_BROWSE = "Card Browse";
public static CardLayout cardLayout = new CardLayout();
public static JPanel card = new JPanel(cardLayout);
public static sampleDemo sd = new sampleDemo();
public sampleDemo() {
WindowAdd wina = new WindowAdd();
card.add(wina, CARD_ADD);
WindowBrowse winb = new WindowBrowse();
card.add(winb, CARD_BROWSE);
setLayout(new BorderLayout());
add(card, BorderLayout.PAGE_END);
}
public static void createAndShowGUI() {
JPanel buttonPanel = new JPanel();
JButton addButton = new JButton("Add");
JButton browseButton = new JButton("Browse");
addButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent ae) {
cardLayout.show(card, "Card Add");
}
});
browseButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent ae) {
cardLayout.show(card, "Card Browse");
}
});
buttonPanel.add(addButton);
buttonPanel.add(browseButton);
JFrame frame = new JFrame("Sample Demo");
frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
frame.getContentPane().add(buttonPanel, BorderLayout.PAGE_END);
frame.getContentPane().add(sd);
frame.setSize(300, 200);
frame.setLocationByPlatform(true);
frame.setVisible(true);
}
class WindowAdd extends JPanel {
public ActionListener action;
public WindowAdd() {
init();
}
public void init() {
JTextField textField = new JTextField(10);
NodeSample newNode = new NodeSample();
JPanel content = new JPanel(new FlowLayout());
JButton saveButton = new JButton("Save");
saveButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
newNode.textContent = textField.getText();
s.insert(newNode);
}
});
content.add(textField);
content.add(saveButton);
textField.setText(null);
add(content);
}
}
class WindowBrowse extends JPanel {
public WindowBrowse() {
init();
}
public void init() {
setLayout(new GridLayout(1, 3));
JButton a = new JButton();
JButton b = new JButton();
JButton c = new JButton();
try {
a = new JButton(s.head.textContent);
b = new JButton(s.head.next.textContent);
c = new JButton(s.head.next.next.textContent);
}catch (NullPointerException e) {
//
}
add(a);
add(b);
add(c);
}
}
class NodeSample {
String textContent;
NodeSample next;
}
class SampleSave {
NodeSample head;
NodeSample tail;
public void insert(NodeSample add) {
if(head == null){
head = add;
tail = add;
}else {
add.next = head;
head = add;
}
}
}
}
In order to change the text on a JButton use something similar to this in your action listener
btn.setText(textfield.getText());
This will change the text of whatever button to the text entered in the textfield

I'm new to java and for some reason I don't know any other way to transfer the data from another frame after pressing submit. For example, it will show the output frame the label and textfield that the user wrote in the first frame like this "Name: "user's name". If you do know please post the code I should put, thank you!

It's not clear what problem you are having displaying a value from one field in another frame. But here's an example of doing that (with fields reduced to just one for demonstration):
public class EventDriven extends JFrame {
private final JTextField nameField = new JTextField(15);
private final JButton submit = new JButton("Submit");
private final JButton clear = new JButton("Clear All");
public EventDriven() {
setTitle("Input");
setLayout(new FlowLayout(FlowLayout.CENTER));
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
add(new JLabel("Name: "));
add(nameField);
submit.addActionListener(this::showOutput);
add(submit);
clear.addActionListener(this::clearInput);
add(clear);
pack();
}
private void showOutput(ActionEvent ev) {
submit.setEnabled(false);
JDialog output = new JDialog(EventDriven.this, "Output", true);
output.add(new Label("Name: " + nameField.getText()), BorderLayout.CENTER);
JButton okButton = new JButton("OK");
output.add(okButton, BorderLayout.SOUTH);
okButton.addActionListener(bv -> output.setVisible(false));
output.pack();
output.setVisible(true);
}
private void clearInput(ActionEvent ev) {
nameField.setText(null);
submit.setEnabled(true);
}
public static void main(String[] args) {
EventDriven window = new EventDriven();
window.setVisible(true);
}
}
You will also see that I've simplified your action listeners to demonstrate an easier way to respond to user driven event.s
I made a JFrame with JTextField, JPanel and a button in which the user inputs a value and after clicking the button, it will generate multiple labels based on the users input, but the JLabel doesnt appear. am i doing it wrong?
this is the coding for the button.
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
String s = jTextField1.getText();
int noSub = Integer.valueOf(s);
addData(noSub);
}
and this is the method to add JLabel.
public void addData(int a){
jPanel1.removeAll();
int num = a;
JLabel jLabel[] = new JLabel[num];
for(int i=0;i<num;i++){
jLabel[i]=new JLabel();
jLabel[i] = new JLabel("Label "+i);
jPanel1.add(jLabel[i]);
jPanel1.revalidate();
jPanel1.repaint();
}
jPanel1.updateUI();
}
Made a simple working example here:
public class Sample extends JFrame{
private JTextField inputField;
private JPanel outputPanel;
private Sample() {
JPanel mainPanel = new JPanel(new BorderLayout());
JPanel form = new JPanel(new GridBagLayout());
inputField = new JTextField(3);
JButton submitBtn = new JButton("Enter");
form.add(inputField);
form.add(submitBtn);
mainPanel.add(form, BorderLayout.NORTH);
outputPanel = new JPanel();
mainPanel.add(outputPanel);
submitBtn.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
String text = inputField.getText();
int noSub = Integer.valueOf(text);
addData(noSub);
}
void addData(int data){
outputPanel.removeAll();
JLabel jLabel[] = new JLabel[data];
for(int i=0;i<data;i++){
jLabel[i] = new JLabel("Label "+i);
outputPanel.add(jLabel[i]);
}
outputPanel.revalidate();
outputPanel.repaint();
// No need to call outputPanel.updateUI()
}
});
setSize(400,500);
add(mainPanel);
setVisible(true);
setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
}
public static void main(String[] args) {
new Sample();
}
}
I have a class BasicInfoWindow that gets the user information such as name, address, etc. I then have another class ReviewandSubmit where it show the the texts the user entered from BasicInfoWindow in the JTextArea. I am using card layout to switch between each panel. I am not sure how to send the info from BasicInfoWindow and receive it from ReviewandSubmit. Here is my code so far:
import javax.swing.*;
import java.awt.*;

showReview.append(getInfo.sendInfo().toString());
panel.add(centerPanel);
}

{
JPanel southPanel = new JPanel();
panel.add(southPanel, BorderLayout.SOUTH);
btnSubmit = new JButton("SUBMIT");
// creates a new file
southPanel.add(btnSubmit);
}
}
You could use a Singleton Pattern in the HiringPersonInfo class to instantiate one instance of the class and then during the submit you could add that instance of that class to an ArrayList.
Singleton Patterns can be used to create one instance of the object that can be shared by all the classes in that package. You can think of it like a "global" variable in a way for OOP.
I have problem with this code
when I click on file and click on new ,new panel comes to screen and when I want to change JRadioBox status to change Label status,Label status changes but also the panel goes away :(
public class MainClass {
public static void main(String[] args) {
new MainFrame();
}
}
class Toolbar extends JPanel {
private JRadioButton Status1;
private JRadioButton Status2;
private ButtonGroup radioButtonGroup;
public Toolbar() {
super();
setLayout(new FlowLayout());
Status1 = new JRadioButton("Status1");
Status2 = new JRadioButton("Status2");
radioButtonGroup = new ButtonGroup();
radioButtonGroup.add(Status2);
radioButtonGroup.add(Status1);
Status1.addItemListener(new ItemListener() {
#Override
public void itemStateChanged(ItemEvent e) {
MainFrame m = new MainFrame();
m.l.setText("Status1");
}
});
Status2.addItemListener(new ItemListener() {
#Override
public void itemStateChanged(ItemEvent e) {
MainFrame m = new MainFrame();
m.l.setText("Status2");
}
});
add(Status1);
add(Status2);
}
}
class Panel extends JPanel {
public Panel() {
super();
setBackground(Color.MAGENTA);
}
}
class MenuBar extends JMenuBar {
private JMenu menu;
private JMenuItem fileItems;
public boolean panel = false;
public MenuBar() {
super();
menu = new JMenu("File");
add(menu);
fileItems = new JMenuItem("New");
menu.add(fileItems);
fileItems.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
MainFrame mf = new MainFrame();
Panel p = new Panel();
mf.addPanel(p);
mf.add(new Toolbar(), BorderLayout.NORTH);
repaint();
}
});
}
}
class MainFrame extends JFrame {
public static JLabel l;
public MainFrame() {
setDefaultCloseOperation(EXIT_ON_CLOSE);
setSize(400, 400);
l = new JLabel("No Status");
add(l, BorderLayout.SOUTH);
MenuBar mb = new MenuBar();
setJMenuBar(mb);
setVisible(true);
}
public void addPanel(Panel p) {
add(p, BorderLayout.CENTER);
}
}
Stop making new MainFrames all over the place. Create it once and maintain a handle to it for whenever you need it.
I have been googling an sherthing for an solution to this problem a lot but can't find any answer how to fix this. My problem is that when i start a new jframe from an actionevent from pressing a button the class white the JFrame opens but then the programs starts to freeze and the pop up windows stays blank.
Her is the cod i apologize if there is some bad programing or some words in swedish:
The start upp class:
import java.util.ArrayList;
public class maineClassen {
ArrayList<infoClass> Infon = new ArrayList<>();
public static void main (String [] args)
{
referenser referens = new referenser();
Startskärmen ss = new Startskärmen(referens);
}
}
The "startskärm" the first screen to com to:
public class Startskärmen extends JFrame implements ActionListener {
referenser referens;
ArrayList<infoClass> Infon;
JButton öppna = new JButton("open");
JButton ny = new JButton("create new");
JButton radera = new JButton("erase");
JScrollPane pane = new JScrollPane();
DefaultListModel mod = new DefaultListModel();
JList list = new JList(mod);
JScrollPane sp = new JScrollPane(list);
JLabel texten = new JLabel("pre-alpha 0.1");
public Startskärmen(referenser re)
{
//references should be sent by itself or received
referens = re;
Infon = referens.getInfoReferens();
//build up the window
JPanel labelPanel = new JPanel();
labelPanel.setLayout(new BoxLayout(labelPanel, BoxLayout.LINE_AXIS));
labelPanel.setBorder(BorderFactory.createEmptyBorder(10,10,0,10));
labelPanel.add(texten);
JPanel scrollPanel = new JPanel();
scrollPanel.setLayout(new BoxLayout(scrollPanel, BoxLayout.LINE_AXIS));
scrollPanel.setBorder(BorderFactory.createEmptyBorder(10,10,10,10));
scrollPanel.add(sp);// man kan ocksä sätta in --> pane <--
JPanel buttonPanel = new JPanel();
buttonPanel.setLayout(new BoxLayout(buttonPanel, BoxLayout.LINE_AXIS));
buttonPanel.setBorder(BorderFactory.createEmptyBorder(0, 10, 10, 10));
buttonPanel.add(Box.createHorizontalGlue());
buttonPanel.add(öppna);
buttonPanel.add(Box.createRigidArea(new Dimension(10, 0)));
buttonPanel.add(ny);
buttonPanel.add(Box.createRigidArea(new Dimension(10, 0)));
buttonPanel.add(radera);
Container contentPane = getContentPane();
contentPane.add(labelPanel,BorderLayout.NORTH);
contentPane.add(scrollPanel, BorderLayout.CENTER);
contentPane.add(buttonPanel, BorderLayout.PAGE_END);
setVisible(true);
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
pack();
setSize(500, 500);
//adda action listener
ny.addActionListener(this);
öppna.addActionListener(this);
radera.addActionListener(this);
//skapaNyIC();
}
infoClass hh;
public void skapaNyIC()
{
Infon.add(new infoClass());
Infon.get(Infon.size() -1).referenser(Infon); //Infon.get(Infon.size() -1)
mod.addElement(Infon.get(Infon.size() -1).getName());
}
public void actionPerformed(ActionEvent e) {
if(e.getSource() == ny)
{
skapaNyIC();
}
else if(e.getSource() == öppna)
{
JOptionPane.showMessageDialog(texten,"This function doesn't exist yet");
}
else if(e.getSource() == radera)
{
JOptionPane.showMessageDialog(texten, "This function doesn't exist yet");
}
}
}
The class where the information will be stored and that creates the window (class) that will show the info:
public class infoClass {
ArrayList<infoClass> Infon;
private infoClass ic;
private String namn = "inget namn existerar";
private String infoOmInfo = null;
private int X_Rutor = 3;
private int Y_Rutor = 3;
private String[] information = new String[X_Rutor + Y_Rutor];
//info om dessa värden
public infoClass()
{
}
public void referenser(infoClass Tic)
{
ic = Tic;
infonGrafiskt ig = new infonGrafiskt(ic);
}
public void referenser(ArrayList<infoClass> Tic)
{
ic = Tic.get((Tic.size() - 1 ));
System.out.println("inna");
infonGrafiskt ig = new infonGrafiskt(ic);
ig.setVisible(true);
System.out.println("efter");
}
public String namnPåInfon()
{
return namn;
}
//namnen
public String getName()
{

}
public void setNamn(String n)
{

}
//y kordinaterna
public int getY_Rutor()
{

}
public void setY_Rutor(int n)
{
Y_Rutor = n;
}
//informationen
public String[] getInformationen()
{
return information;
}
public void setInformationen(String[] n)
{
information = n;
}
//infoOmInfo
public String getinfoOmInfo()
{

}
public void setinfoOmInfo(String n)
{

}
}

so my problem now is that i can't create a new "infoclass" that will show the info in the "infoGrafikst" class. with the code:
Infon.add(new infoClass());
Infon.get(Infon.size() -1).referenser(Infon); //Infon.get(Infon.size() -1)
mod.addElement(Infon.get(Infon.size() -1).getName());
that am triggered by an button click.
Sorry for all the cod, but didn't know how to show my problem in another way.
Thanks a lot. I did find out that it was this code
int m =1;
try {
while(m ==1) {
Thread.sleep(100);
if(pausa == false)
m =2;
}
} catch(InterruptedException e) {
}
that made it not work...
Well I haven't gone through your code may be beacuse I am too lazy to read pages of code.Well i think the new window you are creating must be interfering with EDT.
Well i have done a short example which may help you, and its smooth:
import java.awt.event.ActionEvent;
import javax.swing.*;
public class FrameLaunch {
void inti(){
final JFrame f=new JFrame();
final JFrame f2=new JFrame();
final JTextArea ja=new JTextArea();
JButton b =new JButton("press for a new JFrame");
f2.add(b);
f2.pack();
f2.setVisible(true);
b.addActionListener(new java.awt.event.ActionListener()
{
public void actionPerformed(ActionEvent e) {
f2.setVisible(false);
f.setSize(200,200);
ja.setText("THIS IS NOT FROZEN");
f.add(ja);
f.setVisible(true);
f.setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
}
});
}
public static void main(String[] args)
{
FrameLaunch frame = new FrameLaunch();
frame.inti();
}
}
