thread-sleep

I am trying to make my JButton flicker red for this game I am creating. All the solutions on this website suggest using a thread and putting it to sleep or using a timer, however, the pause allays seems to come after the color change Here is my code: Color cb = board[Y1][X1].getBackground(); board[Y1][X1].setBackground(Color.RED); //Pause board[Y1][X1].setBackground(cb); If I put a thread and put it to sleep on line 3 and comment out line 4 the pause will come before the JButton is turned red. (Note board is just a 2D array of JButtons) There are any number reasons why this might be occurring

I have a SwingWorker class which loads a text file and slices it to chunks for further processing. This is the SwingWorker class: public class ConverterWorker extends SwingWorker<String, String> { private final File f; private final JLabel label; public ConverterWorker(File f, JLabel label) { this.f = f; this.label = label; } @Override protected String doInBackground() throws Exception { NMTMain.convertableData = getDataSets(f); if(!NMTMain.convertableData.isEmpty()) { return "Done"; } else { publish("Failed to load the file!"); return "Failed"; } } @Override public void done() { try { label

I made a blackjack game, and I want the AI player to pause between taking cards. I tried simply using Thread.sleep(x), but that makes it freeze until the AI player is done taking all of his cards. I know that Swing is not thread safe, so I looked at Timers, but I could not understand how I could use one for this. Here is my current code: while (JB.total < 21) { try { Thread.sleep(1000); } catch (InterruptedException ex) { System.out.println("Oh noes!"); } switch (getJBTable(JB.total, JB.aces > 0)) { case 0: JB.hit(); break; case 1: break done; case 2: JB.hit(); JB.bet *= 2; break done; } } BTW

Possible Duplicate: using sleep() for a single thread I'm having issues with JTextField.setText() when using Thread.sleep(). This is for a basic calculator I'm making. When the input in the input field is not of the correct format I want "INPUT ERROR" to appear in the output field for 5 seconds and then for it to be cleared. The setText() method did work when I just set the text once to "INPUT ERROR" and by printing out the text in between I found it does work with both that and the setText("") one after the other. The problem arises when I put the Thread.sleep() between them. Here's a SSCCE

First off, I am a beginner in C# and I would like to make this: class2.method_79(null, RoomItem_0, num, num2, 0, false, true, true); System.Threading.Thread.Sleep(250); class2.method_79(null, RoomItem_0, num, num4, 0, false, true, true); System.Threading.Thread.Sleep(300); class2.method_79(null, RoomItem_0, num, num6, 0, false, true, true); But this solution freezes the UI, how could I make the second event occur 250ms after the first etc without freezing the UI? The simplest way to use sleep without freezing the UI thread is to make your method asynchronous. To make your method asynchronous

I tried to use the below code to make a 2 second delay before navigating to the next window. But the thread is invoking first and the textblock gets displayed for a microsecond and landed into the next page. I heard a dispatcher would do that. Here is my snippet: tbkLabel.Text = "two mins delay"; Thread.Sleep(2000); Page2 _page2 = new Page2(); _page2.Show(); Phil 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
