I was searching for a simple solution without window focus. Jayk’s answer, pynput, works perfect for me. Here is the example how I use it. from pynput import keyboard def on_press(key): if key == keyboard.Key.esc: return False # stop listener try: k = key.char # single-char keys except: k = key.name # other keys if … Read more
Yep, you’ll see the arrow keys respond to keyPressed and keyReleased, not keyTyped. My SSCCE: import java.awt.Dimension; import java.awt.event.KeyAdapter; import java.awt.event.KeyEvent; import javax.swing.*; public class ArrowTest extends JPanel { private static final int PREF_W = 400; private static final int PREF_H = PREF_W; public ArrowTest() { setFocusable(true); requestFocusInWindow(); addKeyListener(new KeyAdapter() { @Override public void keyTyped(KeyEvent … Read more
when should you prefer one rather than the other? Prefer Key Bindings since they were introduced. A KeyListener is a lower level connection with events. That page for the key bindings covers a lot of the reasons I would tend to use them rather than a KeyListener. It lists many things which are simply ‘not … Read more
If you search this problem, you’ll see that it is asked and has been solved many times. KeyListeners need to be on the focused component to work. One solution is to give your component the focus after first making it focusable. Better by a long shot however is to use Key Bindings. Google the tutorial … Read more
From a JavaRanch Forum post. Key press and release handlers are added on the scene and update movement state variables recorded in the application. An animation timer hooks into the JavaFX pulse mechanism (which by default will be capped to fire an event 60 times a second) – so that is a kind of game … Read more
If you don’t want to register a listener on every component, you could add your own KeyEventDispatcher to the KeyboardFocusManager: public class MyFrame extends JFrame { private class MyDispatcher implements KeyEventDispatcher { @Override public boolean dispatchKeyEvent(KeyEvent e) { if (e.getID() == KeyEvent.KEY_PRESSED) { System.out.println(“tester”); } else if (e.getID() == KeyEvent.KEY_RELEASED) { System.out.println(“2test2”); } else if … Read more
