I am new to Java and trying to build an application that receives 6 inputs from JSwing TextFields. I have around 5 checkboxes. Based on the selection, some of the details are fetched from database. All other things are working now, but I want to place a progress bar that updates the value based on the progress. I tried manually updating the ProgressBars with progressBar.setValue(0) to progressBar.setValue(100) across checkboxes. But it did not get updated. After going through some of the articles online, I found using swing worker from this link. I tried Robin's solution. How do I make my SwingWorker example work properly? . It creates a separate dialog but, it is empty.
Is there a way I can set progress bar updating in my program?
jButton1 = new javax.swing.JButton();
jButton1.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
progressBar.setValue(0);
if(Sizing_details.isSelected()) {
progressBar.setValue(20);
}
Then I tried using swing worker from the link I mentioned.
public void actionPerformed(ActionEvent e) {
new GuiWorker().execute();
The dialog is struck and nothing shows up. But Functionality wise it works. Could you please help me how I can fix it.
I have two questions.
- Is it possible to update ProgressBar manually whenever I set them inside a checkbox under submit button action. ?
- If I have to use swing worker, is it possible to add a progressbar in the same frame and manipulate it.
EDIT I:
I can make the Progress bar pop up. However, When I call the "go" method from the link below SwingWorker ProgressBar
inside my Jbutton action event , it shows a blank screen.
But when I call the same method inside run method it works fine.
java.awt.EventQueue.invokeLater(new Runnable() {
public void run() { go();
try {
new JFrame_Demo().setVisible(true);
jButton1.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
The above code works. it initialises a progress bar.
java.awt.EventQueue.invokeLater(new Runnable() {
public void run() {
try {
new JFrame_Demo().setVisible(true);
jButton1.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
go();
the above code shows a blank white screen.
