I've read a few books about Java. In all of them there was at least one chapter teaching GUI programming. In all of them, creating a simple form application was following this logic: MyFrame.java public class MyFrame extends JFrame { JButton button1; public MyFrame() { button1 = new JButton("Click here."); } } FrameTest.java: public class FrameTest { public static void main(String[] args) { MyFrame myFrame = new MyFrame(); myFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); myFrame.setSize(600, 600); myFrame.setVisible(true); } } Basically, just subclass JFrame to create a form and declare

I found many answers about my question, but I still don't understand why my application does not throw any exceptions. I created a new java form application in NetBeans 8. My form is created and displayed in main method like this: public static void main(String args[]) { /* Set the Nimbus look and feel */ //<editor-fold defaultstate="collapsed" desc=" Look and feel setting code (optional) "> /* If Nimbus (introduced in Java SE 6) is not available, stay with the default look and feel. * For details see http://download.oracle.com/javase/tutorial/uiswing/lookandfeel/plaf.html */ try { for (javax

So my JProgressBar I have set up doesn't work the way I want it. So whenever I run the program it just goes from 0 to 100 instantly. I tried using a ProgressMonitor , a Task, and tried a SwingWorker but nothing I tried works. Here is my program: int max = 10; for (int i = 0; i <= max; i++) { final int progress = (int)Math.round( 100.0 * ((double)i / (double)max) ); EventQueue.invokeLater(new Runnable() { @Override public void run() { try { Thread.sleep(1000); } catch (InterruptedException ex) { Logger.getLogger(BandListGenerator.class.getName()).log(Level.SEVERE, null, ex); } jProgressBar2

Is there any equivalent of Java's invokeLater() method of SwingUtilities in Javascript? UPDATE 1 So, will setTimeout() with zero delay do exactly the same as invokeLater() ? Tomasz Nurkiewicz If you want to run something asynchronously ( later ), try setTimeout() JavaScript is single-threaded. If you want to run some time consuming (CPU-intensive) task outside of the event handler, you can do this using the technique above, however it will still consume event-handling thread (cause your UI to freeze). It is generally a bad idea to run CPU-intensive tasks inside a browser ( web workers might

I have read a number of articles on the internet about when something should run in the EDT, and when it shouldn't. But I'm still not sure I understand, so I'd like to ask a few question about this: What pieces of code are going to run by default inside the EDT? What pieces of code are going to be run be default outside the EDT? When should I use InvokeLater() so something that by default would run outside the EDT, will run inside it? When should I prevent a piece of code from running (by default) inside the EDT, by creating a new thread and putting that code inside it? Thanks All the code

What is the difference between: //Some code, takes a bit of time to process (new SomeJFrame()).setVisible(true); SwingUtilities.invokeLater(new Runnable() { @Override public void run() { (new SomeJWindow()).start();//Start a new thread } }); And: class doGraphics extends SwingWorker<Void, Object> { @Override public Void doInBackground() { //Some code, takes a bit of time to process (new SomeJFrame()).setVisible(true); return null; } @Override protected void done() { (new SomeJWindow()).start();//Start a new thread } } (new doGraphics()).execute(); Which method is better to use? SwingUtilities

Possible Duplicate: What does SwingUtilities.invokeLater do? SwingUtilities.invokeLater I have seen this little piece of code hundreds of times: public static void main(String[] args) { javax.swing.SwingUtilities.invokeLater(new Runnable() { public void run() { createAndShowGUI(); } }); } Now my question is: what does invokeLater() do? What kind of bad things will happen if I just create and show my GUI inside the main thread? Nothing bad will happen if you're updating it from the EDT while following guidelines . That is... If invokeLater is called from the event dispatching thread -- for

I have this code snippet import javax.swing.SwingUtilities; public class Client1 { public static void main( String[] args ) { SwingUtilities.invokeLater( new Runnable() { public void run() { //new MyWindow( "Bayog" ); new MyWindowV2( "Bayog" ); } } ); } } what is the difference if i will not use SwingUtilities? Suppose the code within the run method modifies a UI element. If you try to execute that code from a non-UI thread, it will fail: all UI operations must be performed in the UI thread (aka the event dispatch thread ). SwingUtilities.invokeLater allows you to say "run this bit of code,
