swingworker

I have to query database to get data to write on JLabel and to accelerate opening dialog I have created JLabel with no text and set text after done a SwingWorker process but JLabel text doesn't be updated Is there any way to achieve this Here is my dialog's src code: package com.caisse.caisseFrame.dialogs; import java.awt.Dimension; import java.awt.Font; import java.awt.GridBagConstraints; import java.awt.GridBagLayout; import java.awt.Image; import java.awt.Insets; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.io.IOException; import javax.imageio.ImageIO

It seems like the long-running tree walker task should be defined in a class like so: public class TreeWalker extends SwingWorker<Void,String> implements FileVisitor<Path> And begun somewhere like so: TreeWalker walker = (new TreeWalker()); walker.execute(); The long-running task is not only initiated by but completely carried out by a single call to walkFileTree() , a method in the Files class. So surely the call to it has to be in doInBackGround() . protected Void doInBackground() throws Exception { Files.walkFileTree(SearchyGUI.p , this); return null; } Note that walkTreeFile() internally

After many attempts trying to make a JProgressBar work as expected, I finally became successful at achieving my goal. I had used @MadProgrammer 's advice and used a SwingWorker to finally get the program work as I want. Now, I want the cursor to change into when my JProgressBar goes from 0% to 100%. I've googled and found out that setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR)); is the code to do it. I've tried it but it does not work as expected. Relevant piece of code: JProgressBar progress; JButton button; JDialog dialog; //Fields of my GUI class progress=new JProgressBar

actually i have called the swing worker from a frame (Suppose) A.. in the swing worker class in do-in-Background method i have certain db queries and i am calling frame B too.. in the done() method however i want to dispose the frame A.. how can i do that..? i cannot write dispose() in frame A class because that results in disposing of frame before the new frame(frame B) is visible... Please help!! class frameA extends JFrame{ public frameA(){ //done some operations.. SwingWorker worker=new Worker(); worker.execute(); } public static void main(string[] args){ new frameA(); } } and in worker

I am using JProgressBar for Showing The Progress Of Data Loaded From from DataBase . I am using SwingWorker Class To Load The Data In BackGround Thread using Tutorial ! The Property Change Event of ProgressBar Of my application is not firing. Please guide me what i am doing wrong???. Below is the SSCCE of the code i am trying to use is as follows. public final class JProgressBarApplication { //private static org.jdesktop.swingx.JXDatePicker dpDate; javax.swing.JPanel pnlDate; JLabel label; JProgressBar pb; boolean taskDone=false; LongRunProcess lrpTask; public static void main(String... aArgs)

I am trying to follow the Java best practices by not doing long tasks on the main thread (EDT). So I am planning to use a swingWorker with Modal Dialog. This way the modal dialog blocks the user for doing anything until that task is done and I can update status on the dialog while the process is taking place. Now the problem is that with the modal dialog, it not only blocks the user but also nothing after setVisible gets called So if I do dialog.setVisible(true); new SwingWorkerTask().execute(); //This does not get called and if I do new SwingWorkerTask().execute(); dialog.setVisible(true); //

QUESTION SOLVED!!!!!! Many thanks to trashgod and HoverCraftFullOfEels! I finally got the concept by using the below example and altering it slightly. The alteration allows scaling the progress bar (by default is 100 units). Again, THANK YOU for your patience and willingness to work through this. Means a lot guys, ~Kyte ps - +1's all 'round :) /** @see http://stackoverflow.com/questions/4637215 */ public class Threading_01 extends JFrame { private static final String s = "0.00"; private JProgressBar progressBar = new JProgressBar(0, 100); private JLabel label = new JLabel(s, JLabel.CENTER);
