The setProgress() API notes: “For performance purposes all these invocations are coalesced into one invocation with the last invocation argument only.” Adding Thread.sleep(1) simply defers the coalescence; invoking println() introduces a comparable delay. Take heart that your file system is so fast; I would be reluctant to introduce an artificial delay. As a concrete example … Read more
There is a Java FX event dispatch thread, which handle all GUI-related tasks. You must update all UI components in this thread. Long-running tasks, like Thread.sleep should never be executed in this thread, since windows will hang, and the GUI will be frozen. Execute all your code in the application main thread, and perform only … Read more
When you use Thread.sleep() you’re doing it on the main thread. This freezes the gui for five seconds then it updates the outputField. When that happens, it uses the last set text which is blank. It’s much better to use Swing Timers and here’s an example that does what you’re trying to accomplish: if (match) … Read more
The simplest way to use sleep without freezing the UI thread is to make your method asynchronous. To make your method asynchronous add the async modifier. private void someMethod() to private async void someMethod() Now you can use the await operator to perform asynchronous tasks, in your case. await Task.Delay(milliseconds); This makes it an asynchronous … Read more
The call to Thread.Sleep is blocking the UI thread. You need to wait asynchronously. Method 1: use a DispatcherTimer tbkLabel.Text = “two seconds delay”; var timer = new DispatcherTimer { Interval = TimeSpan.FromSeconds(2) }; timer.Start(); timer.Tick += (sender, args) => { timer.Stop(); var page = new Page2(); page.Show(); }; Method 2: use Task.Delay tbkLabel.Text = … Read more
Can anyone tell me why sleeping one thread is stopping my whole execution to better explain your Swing GUI is created on its own special thread separate from that which main() and other code will run in, this is done via creating your Swing components in the SwingUtilities.invokeXXX block (even if you have not done … Read more
If you want to pause then use java.util.concurrent.TimeUnit: TimeUnit.SECONDS.sleep(1); To sleep for one second or TimeUnit.MINUTES.sleep(1); To sleep for a minute. As this is a loop, this presents an inherent problem – drift. Every time you run code and then sleep you will be drifting a little bit from running, say, every second. If this … Read more
