How to update values of a JFrame main after using a JDialog of Java Swing?

I have a main window called MainFrame which is a jForm to which I update the data depending on a timer, but the problem is that I cannot update the data in the same MainFrame after using the jdialog, since I end up creating another duplicate window, but with the data changed, one with the original timer and the other with the new timer, I know that I can close the first window with dispose() and then keep the second, but I would like to avoid changing windows so much
the code with which I create another window when pressing the jDialog button is the following
private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {//GEN-FIRST:event_jButton1ActionPerformed
// TODO add your handling code here:
String textoFieldTimer = jTextField1.getText();
int timeUserConfig = Integer.parseInt(textoFieldTimer);
Timer timeDefault = new Timer(timeUserConfig, null);
TokenAccess token = new TokenAccess();
token.access_code = code;
MainFrame mainFrame = new MainFrame(token);
mainFrame.setVisible(true);
mainFrame.timeDefault.stop();
mainFrame.timeDefault = timeDefault;
mainFrame.setUpdateTime(timeUserConfig);
this.dispose();
}//GEN-LAST:event_jButton1ActionPerformed
Is there any alternative to update the window? something like mainFrame.update(); or maybe send the value of the jTextField from the jDialog to mainFrame? since the previous code creates another MainFrame for me.
Method main setLabel and Timer.start/stop
public void setUpdateTime(int timeUserConfig) {
this.timeUserConfig = timeUserConfig;
if (timeUserConfig == 0) {
timeDefault.start();
timeDefault.addActionListener(new java.awt.event.ActionListener() {
#Override
public void actionPerformed(java.awt.event.ActionEvent evt) {
setLabelText();
String timeUserConfigStr = Integer.toString(timeDefaultInt);
tiempoActualizado.setText("Tiempo de Actualizado: " + timeUserConfigStr+"ms");
}
});
} else {
timeDefault.stop();
timeDefault = new Timer(timeUserConfig, null);
timeDefault.start();
timeDefault.addActionListener(new java.awt.event.ActionListener() {
#Override
public void actionPerformed(java.awt.event.ActionEvent evt) {
setLabelText();
String timeUserConfigStr = Integer.toString(timeUserConfig);
tiempoActualizado.setText("Tiempo de Actualizado: " + timeUserConfigStr+"ms");
}
});
}
}
setLabelText is a method set of label
public void setLabelText() {
String humedadStr = String.valueOf(humedad);
String temperaturaStr = String.valueOf(temperatura);
String presionStr = String.valueOf(co2);
temporalHum.setText(humedadStr);
temporalTemperatura.setText(temperaturaStr);
temporalPresion.setText(presionStr);
}
Any help would be appreciated.

Thanks for the update, and I found another solution without using an OptionPane from this question: programmatically close a JPanel which is displayed in JDialog.
I cannot replicate your codings
Start with the MainFrame, assuming you opened the JDialog by clicking on a button and wants to setText() to label lbSomething:
private void btInputActionPerformed(java.awt.event.ActionEvent evt) {
// Open new JDialog when button is clicked
NewJDialog dialog = new NewJDialog(new javax.swing.JFrame, true);
dialog.setVisible(true);
// Get user input from JDialog
String temp = dialog.getInput();
if (temp != null) {
/*
* Perform jButton1ActionPerformed() content here
* Including timeUserConfig, timeDefault and setUpdateTime() here
* so that you don't have to access mainFrame in the JDialog.
*/
lbSomething.setText(temp);
}
}
Then about the JDialog (with simple input detection):
public class NewJDialog extends javax.swing.JDialog {
// Set the variable as class variable
private String textTOFieldTimer;
public NewJDialog(java.awt.Frame parent, boolean modal) {
// default contents
}
#SupressWarinings("unchecked")
private void initComponents() {
// default contents
}
private void btSaveAction Performed(java.awt.event.ActionEvent evt) {
// Check if input correct and whether to disable JDialog
if (tfInput.getText.length() != 0) {
input = tfInput.getText();
// Connect to the whole JDialog by getWindowAncestor()
Window window = SwingUtilities.getWindowAncestor(NewJDialog.this);
// Just setVisible(false) instead of dispose()
window.setVisible(false);
} else {
JOptionPane.showMessageDialog(this, "Wrong Input");
}
}
public String getInput() {
return textToFieldTimer;
}
// default variables declarations
}
Hope this answer helps you well.
Would be better if you displayed the source code, but a simple solution to update values to an existing JFrame is by using setText() and getText().
For example:
String input = JOptionPane.showInputDialog(this, "Nuevo valor");
lbPresionActual.setText(input);
If you created a self-defined JDialog, it is about to transfer the input value when closing the JDialog, and that could be a different question.

Calling a JFrame method from another JFrame on Button Click

I searched on stack overflow for the similar answers for my question, but neither of them helped me.
So my problem is the following:
I have a main JFrame called Main_Window, on which I have a JTable and a JButton. After clicking the Button another JFrame (Update_Window) opens from Which I can update the table. The Update_Window JFrame has two TextFields and a SUBMITButton.
Briefly, I want to update my JTable in the Main_Window from the Update_Window JFrame. After I type something in the TextFields and Submit with the Button, the data should appear in the Main_Window's JTable, but it is not working.
This is my Main_Window JFrame:
private void updateBtnActionPerformed(java.awt.event.ActionEvent evt) {
Update_Window newWindow = new Update_Window();
newWindow.setVisible(true);
newWindow.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
}
public void putDataIntoTable(Integer data, int row, int col) {
jTable1.setValueAt(data,row,col);
}
This is my Update_Window JFrame:
private void submitBtnActionPerformed(java.awt.event.ActionEvent evt) {
quantity = Integer.parseInt(quantityTextField.getText());
price = Integer.parseInt(priceTextField.getText());
Main_Window mw = new Main_Window();
mw.putDataIntoTable(price,3,2);
}
I think my problem is here Main_Window mw = new Main_Window();, because this creates a new Instance and it doesn't add the data to the correct window, or something like that.

Yes, you are right. The line Main_Window mw = new Main_Window(); is definitely wrong.
Better solution is:
public class UpdateWindow extends JFrame {
private final MainWindow mainWindow;
public UpdateWindow(MainWindow mainWin) {
mainWindow = mainWin;
}
private void submitBtnActionPerformed(java.awt.event.ActionEvent evt) {
quantity = Integer.parseInt(quantityTextField.getText());
price = Integer.parseInt(priceTextField.getText());
mainWindow.putDataIntoTable(price,3,2);
}
}
Also you need to correct the call of constructor for UpdateWindow
private void updateBtnActionPerformed(java.awt.event.ActionEvent evt) {
UpdateWindow newWindow = new UpdateWindow(this);
newWindow.setVisible(true);
newWindow.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
}
Please note: I've corrected your class names as it proposed by Java naming convention. Main_Window -> MainWindow, Update_Window -> UpdateWindow.
When my suggestion don't solve your problems, please provide a [mcve] so we can better identify your problems.

Minesweeper Object GUI

I am trying to do a simple Minesweeper game using JFrame, however I am having troubles with the creation of objects. I am creating 96 buttons, some of which get the property of being wrong ("F") and right ("R"):
public class GUIBase extends JFrame {
private JButton button;
private JButton fButton;
public GUIBase() {
super("Minesweeper");
setLayout(new FlowLayout());
//Fields
int position;
for (int i = 0; i < 96; i++) {
position = (int) (Math.random() * 100);
if (position < 80) {
button = new JButton("R");
button.setToolTipText("Is this the correct one?");
add(button);
} else {
fButton = new JButton("F");
fButton.setToolTipText("Is this the correct one?");
add(fButton);
}
}
I then use ActionListener in order to check whether or not the button is correct. If the button is correct, it will get .setEnabled(false), otherwise the game ends:
//Action
Action action = new Action();
button.addActionListener(action);
fButton.addActionListener(action);
}
private class Action implements ActionListener {
public void actionPerformed(ActionEvent event) {
System.out.println("Somethin");
if (event.getSource() == button) {
button.setEnabled(false);
} else if (event.getSource() == fButton) {
JOptionPane.showMessageDialog(null, "You lost!");
System.exit(0);
} else {
JOptionPane.showMessageDialog(null, "An error ocurred");
System.exit(0);
}
}
}
Everything in the game turns out as planned, however only the last correct button ("R") and last wrong one ("F") are connected to the ActionListener. The rest of the buttons do not do anything when pressed.
How can I fix this?

The problem is that you only have two variables (attributes of the class GUIBase, specifically), and your are assigning to it each time you create a new button. Hence, you only have a reference to the last buttons.
You need an array of buttons. Let's see:
public class GUIBase extends JFrame {
public final int MAX_BUTTONS = 96;
private JButton[] buttons;
// ...
}
The next step is to create the array itself at the beginning:
public GUIBase() {
super("Minesweeper");
setLayout(new FlowLayout());
this.buttons = new JButton[MAX_BUTTONS];
//Fields
int position;
for (int i = 0; i < buttons.length; i++) {
position = (int) (Math.random() * 100);
this.buttons[ i ] = new JButton("R");
this.buttons[ i ].setToolTipText("Is this the correct one?");
this.add(this.buttons[ i ]);
Action action = new Action();
this.buttons[ i ].addActionListener(action);
}
}
You'll probably need more depth in arrays in order to completely understand the code. Basically, an array is a continuous collection of variables, which you can index by its position, from 0 to n-1, being n the number of positions.
Then you'll probably be able to fill the gaps yourself.
Hope this helps.

One part of your problems is coming from your action listener.
Of course, one part is that your code probably needs a list/array to keep track of all created buttons; but at least right now, you can rework your code without using arrays/list:
private class Action implements ActionListener {
public void actionPerformed(ActionEvent event) {
System.out.println("Somethin");
if (event.getSource() instanceofJButton) {
JBUtton clickedButton = (JButton) event.getSource();
String buttonText = clickedButton.getText();
if (buttonText.equals("R") ...
else if (buttonText.equals("F")
You see, the whole point here is: as of now, you just need to know what kind of button was created. And your ActionListener knows which button it was clicked on ...

How to call a function when I click on a jPanel (Java)?

I'm working with Netbeans IDE in Java.
I've a form with one JPanel.
Each JPanel has a gridLayout 3x3 and in each place there is an image representing a number[0,1,2,3,4,5,6,7,8](the image is created used a custom class,not just fitting the image in a lab).
I want to be able to exchange two images in the panel when the user click them (First click: no action , second click: switch the two images fitted in the jPanel Components).
I already created a function exchangeComponents and with a test code (like:
exchangeComponents (0,8,jPanel1)
it exchanges correctly the images located in position1 (1st row,1st column) and in position2 (3rd row,3rd column).
The function a creted is the following:
public void exchangeComponents(int component1,int component2,JPanel jpanel){
try{
Component aux1 = jpanel.getComponent(component1);
Point aux1Loc = aux1.getLocation();
Component aux2 = jpanel.getComponent(component2);
Point aux2Loc = aux2.getLocation();
aux1.setLocation(aux2Loc);
aux2.setLocation(aux1Loc);
}
catch (java.lang.ArrayIndexOutOfBoundsException ex){ /* error! bad input to the function*/
System.exit(1);
}
}
I suppose I neeed to have an event that call the function exchangeComponents() when the user click on one of the images on the jPanel1 but how should I do it? and how to check what components (images) the user has selected?
I just know that when I create a Button if a click on it (from the IDE) an event like
private void button1ActionPerformed(java.awt.event.ActionEvent evt) {
// some code..
}
is created and the code I fill in is executed.
Thank you in advance for any hint.

You need to add the same mouse listener to all you JLabels or whatever container you have for your images, like:
img1.addMouseListener(this);
img2.addMouseListener(this);
etc., then detect which Jlabel you clicked with MouseEvent.getSource(); , like this
boolean hasclicked1=false;
JLabel click1label=null;
public void mouseClicked(MouseEvent me){
if(!hasclicked1){ //clicked first pic
hasclicked1 = true;
click1label = (JLabel) me.getSource();
} else { //clicked second pic
hasclicked1 = false;
exchangeComponents(click1label, (JLabel) me.getSource(), /*your jpanel here*/);
}
//now change exchangeComponents so it uses JLabels as parameters
public void exchangeComponents(JLabel component1, JLabel component2, JPanel jpanel){
try{
Component aux1 = component1;
Point aux1Loc = aux1.getLocation();
Component aux2 = component2;
Point aux2Loc = aux2.getLocation();
aux1.setLocation(aux2Loc);
aux2.setLocation(aux1Loc);
} catch (java.lang.ArrayIndexOutOfBoundsException ex) { /* error! bad input to the function*/
System.exit(1);
}
}
If you are not using JLabels for the images though, replace JLabel in the code with whatever you are using...
EDIT: Sorry, I don't think I made this unclear, but your class with the method exchangeComponents has to implement MouseListener. Then, in the mouseClicked event put the code I gave for it. Make sure to include the variables hasclicked1 and click1label in your class. Make you class something like this
public class ComponentExchanger implements MouseListener {
boolean hasclicked1=false;
JLabel click1label=null;
JPanel mainPanel;
public ComponentExchanger(){
//create JFrame, JPanel, etc.
JFrame f=new JFrame();
//etc.
mainPanel=new JPanel();
f.add(mainPanel);
//set layout of panel, etc.
for(int i=0;i<9;i++){
JLabel l=new JLabel(/*label image here*/);
Point loc=new Point(/*coordinates here*/);
l.setLocation(loc);
mainPanel.add(l);
/*more code*/
f.setVisible(true);
}
}
public static void main(String args[]){
new ComponentExchanger();
}
public void mouseClicked(MouseEvent me){
if(!hasclicked1){ //clicked first pic
hasclicked1 = true;
click1label = (JLabel) me.getSource();
} else { //clicked second pic
hasclicked1 = false;
exchangeComponents(click1label, (JLabel) me.getSource(), mainPanel);
}
//now change exchangeComponents so it uses JLabels as parameters
public void exchangeComponents(JLabel component1, JLabel component2, JPanel jpanel){
try{
Component aux1 = component1;
Point aux1Loc = aux1.getLocation();
Component aux2 = component2;
Point aux2Loc = aux2.getLocation();
aux1.setLocation(aux2Loc);
aux2.setLocation(aux1Loc);
} catch (java.lang.ArrayIndexOutOfBoundsException ex) { /* error! bad input to the function*/
System.exit(1);
}
}
//Also, you will need to include the other mouselistener implemented methods, just
//leave them empty
}

First of all, to be technical it's methods not functions.
There are a couple of ways you could do this. You could go ahead with actionListener, but then you would probably need buttons or something.
Or you could use MouseListener, and detect clicks over a certain region of the panel.
For the switching algorithm, perhaps an array of 2 images. There is a variable that increases by 1 every click. When the variable is 2, it resets back to 0.
clicks++; //every time the mouse is clicked; clicks starts out at 0
if(clicks == 2){
clicks = 0; //at the end of the listener method
}
On the first click the clicked image goes into the first array slot, because the user has clicked once.
clickImage = imageArray[clicks];
On the second click, the other clicked image goes to the second array slot, because 2 clicks have been detected. In this case, your exchangeComponents method would go at the end of the listener method, with the arguments being imageArray[1], imageArray[2], .
You can apply this to ints or whatever, just save the value in an array and use an incrementing and resetting variable.

Passing input from one frame to another(JAVA)

Here's the thing...
I have 2 GUI programs.
A Menu Program,which is basically a frame with buttons of food items,the buttons when clicked
opens this other program,an Input Quantity Program,which is a frame with a text field,buttons for numbers,buttons for Cancel and Confirm. The quantity that is confirmed by the user will be accessed by the menu program from the Input Quantity Program to be stored in a vector so that every time a user wants to order other food items he will just click another button and repeat the process.
Now I've coded the most part and got everything working except one thing,the value returned by the Input Quantity Program has this delay thing.
This is what I do step by step:
1)Click a food item in Menu,it opens the Input Quantity window.
2)I input the number I want,it displayed in the text box correctly.
3)I pressed confirm which will do 3 things,first it stores the value of the text field to a variable,second it will call the dispose() method and third a print statement showing the value of the variable(for testing purposes).
4)The menu program then checks if the user has already pressed the Confirm button in the Input program,if true it shall call a method in the Input program called getQuantity() which returns the value of the variable 'quantity' and store it in the vector.
5)After which executes another print statement to check if the passed value is correct and then calls the method print() to show the ordered item name and it's recorded quantity.
Here are the screenshots of the GUI and the code will be below it.
ActionPerformed method of the CONFIRM BUTTON in the Input Quantity Program:
private void ConfirmButtonActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:
confirmed = true;
q= textField.getText().toString();
quantity =Integer.parseInt(q) ;
System.out.println("getQTY method inside Input Quantity Interface:" +getQuantity());
System.out.println("Quantity from confirmButton in Input Quantity Interface actionPerformed: "+quantity);
//getQuantity();
}
ACTION LISTENER CLASS of the MENU ITEM BUTTONS in MENU PROGRAM which does step 2 above:
class f implements ActionListener {
#Override
public void actionPerformed(ActionEvent e)
{
inputGUI.setVisible(true);
int q =0;
q=inputGUI.getQuantity(); //call method to get value from Input Program
System.out.println("Quantity inside Menu actionperformed from AskQuantity interface: "+q);
orderedQuantity.add(q); //int vector
textArea.append("\n"+e.getActionCommand()+"\t"+ q);
orderedItems.add(e.getActionCommand()); //String vector
print();
/*
System.out.println("Enter QTY: ");
int qty = in.nextInt();
orderedQuantity.add(qty);
print();*/
}
Here are screenshots of the print statements in the console:
Here I first ordered Pumpkin Soup,I entered a quantity of 1
Here I ordered seafood marinara and entered a quantity of 2
Here I ordered the last item,pan fried salmon and entered a quantity of 3
As you can see the first recorded quantity is 0 for the first item I ordered then when I added another item,the quantity of the first item gets recorded but the 2nd item's quantity is not recorded..same goes after the third item... and the quantity of the 3rd item is not recorded even if the program terminates :(
How can I solve this problem?

I think I see your problem, and in fact it stems directly from you're not using a modal dialog to get your input. You are querying the inputGUI before the user has had a chance to interact with it. Hang on while I show you a small example of what I mean...
Edit
Here's my example code that has a modal JDialog and a JFrame, both acting as a dialog to a main JFrame, and both using the very same JPanel for input. The difference being the modal JDialog will freeze the code of the main JFrame at the point that it has been made visible and won't resume until it has been made invisible -- thus the code will wait for the user to deal with the dialog before it progresses, and therein holds all the difference.
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
public class DialogExample {
private static void createAndShowGui() {
JFrame frame = new JFrame("Dialog Example");
MainPanel mainPanel = new MainPanel(frame);
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.getContentPane().add(mainPanel);
frame.pack();
frame.setLocationByPlatform(true);
frame.setVisible(true);
}
public static void main(String[] args) {
SwingUtilities.invokeLater(new Runnable() {
public void run() {
createAndShowGui();
}
});
}
}
class MainPanel extends JPanel {
private InputPanel inputPanel = new InputPanel();
private JTextField responseField = new JTextField(10);
private JDialog inputDialog;
private JFrame inputFrame;
public MainPanel(final JFrame mainJFrame) {
responseField.setEditable(false);
responseField.setFocusable(false);
add(responseField);
add(new JButton(new AbstractAction("Open Input Modal Dialog") {
#Override
public void actionPerformed(ActionEvent e) {
if (inputDialog == null) {
inputDialog = new JDialog(mainJFrame, "Input Dialog", true);
}
inputDialog.getContentPane().add(inputPanel);
inputDialog.pack();
inputDialog.setLocationRelativeTo(mainJFrame);
inputDialog.setVisible(true);
// all code is now suspended at this point until the dialog has been
// made invisible
if (inputPanel.isConfirmed()) {
responseField.setText(inputPanel.getInputFieldText());
inputPanel.setConfirmed(false);
}
}
}));
add(new JButton(new AbstractAction("Open Input JFrame") {
#Override
public void actionPerformed(ActionEvent e) {
if (inputFrame == null) {
inputFrame = new JFrame("Input Frame");
}
inputFrame.getContentPane().add(inputPanel);
inputFrame.pack();
inputFrame.setLocationRelativeTo(mainJFrame);
inputFrame.setVisible(true);
// all code continues whether or not the inputFrame has been
// dealt with or not.
if (inputPanel.isConfirmed()) {
responseField.setText(inputPanel.getInputFieldText());
inputPanel.setConfirmed(false);
}
}
}));
}
}
class InputPanel extends JPanel {
private JTextField inputField = new JTextField(10);
private JButton confirmBtn = new JButton("Confirm");
private JButton cancelBtn = new JButton("Cancel");
private boolean confirmed = false;
public InputPanel() {
add(inputField);
add(confirmBtn);
add(cancelBtn);
confirmBtn.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent arg0) {
confirmed = true;
Window win = SwingUtilities.getWindowAncestor(InputPanel.this);
win.setVisible(false);
}
});
cancelBtn.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent arg0) {
confirmed = false;
Window win = SwingUtilities.getWindowAncestor(InputPanel.this);
win.setVisible(false);
}
});
}
public boolean isConfirmed() {
return confirmed;
}
public void setConfirmed(boolean confirmed) {
this.confirmed = confirmed;
}
public String getInputFieldText() {
return inputField.getText();
}
}
So solution: use a modal JDialog.

Suppose i am having two GUI frames f1 and f2. Now by clicking a button on f1 i want to invoke frame f2 and also sending some data from f1(frame class) to f2(frame class).
One possible way is to declare a constructor in f2 which takes the same data as parameters which i wanted to send to it from f1.Now in frame f1's coding just include these statements:
f1.setVisible(false);//f1 gets invisible
f2 newFrame=new f2(uname,pass);//uname and pass have been takenfrom f1's text fields
f2.setVisible(true);
I think this will clear up your problem.
