For key pressed and key released events, the getKeyCode method returns the event's keyCode. For key typed events, the getKeyCode method always returns VK_UNDEFINED. The getExtendedKeyCode method may also be used with many international keyboard layouts.

Nov 25, 2012 · I'm writing small graphics editor and I want catch event when I press Ctrl+A. I use such code (this is test version): @Override public void keyPressed(KeyEvent e) { System.out.println("Press"); switch (e.getKeyCode()){ case KeyEvent.VK_A : System.out.println("A"); break; } }

Can anybody provide me with the Key Code integer list for individual keys used on the Keyboard for the KeyEvent class in java? I want to create a dropdown list of all the keyboard keys for the user to select.

Feb 14, 2013 · Do you want to "dispatch" the event or simply pass it back via the KeyListener interface (ie kl.keyPressed(myHandedMadeEvent)? e is the KeyEvent. if you want to see the e value, then you can try this. Creating KeyEvent : Example (dunno if this is the right way, but it produce the right output): KeyEvent e; e = new KeyEvent(a, 1, 20, 1, 10, 'a');

Feb 27, 2025 · An event is a change in the state of an object triggered by some action such as Clicking a button, Moving the cursor, Pressing a key on the keyboard, Scrolling a page, etc. In Java, the java.awt.event package provides various event classes to handle these actions.
