Question

Explanation / Answer

public class KeyEventDemo ... implements KeyListener ... { ...//where initialization occurs: typingArea = new JTextField(20); typingArea.addKeyListener(this); //Uncomment this if you wish to turn off focus //traversal. The focus subsystem consumes //focus traversal keys, such as Tab and Shift Tab. //If you uncomment the following line of code, this //disables focus traversal and the Tab events //become available to the key event listener. //typingArea.setFocusTraversalKeysEnabled(false); ... /** Handle the key typed event from the text field. */ public void keyTyped(KeyEvent e) { displayInfo(e, "KEY TYPED: "); } /** Handle the key-pressed event from the text field. */ public void keyPressed(KeyEvent e) { displayInfo(e, "KEY PRESSED: "); } /** Handle the key-released event from the text field. */ public void keyReleased(KeyEvent e) { displayInfo(e, "KEY RELEASED: "); } ... private void displayInfo(KeyEvent e, String keyStatus){ //You should only rely on the key char if the event //is a key typed event. int id = e.getID(); String keyString; if (id == KeyEvent.KEY_TYPED) { char c = e.getKeyChar(); keyString = "key character = '" + c + "'"; } else { int keyCode = e.getKeyCode(); keyString = "key code = " + keyCode + " (" + KeyEvent.getKeyText(keyCode) + ")"; } int modifiersEx = e.getModifiersEx(); String modString = "extended modifiers = " + modifiersEx; String tmpString = KeyEvent.getModifiersExText(modifiersEx); if (tmpString.length() > 0) { modString += " (" + tmpString + ")"; } else { modString += " (no extended modifiers)"; } String actionString = "action key? "; if (e.isActionKey()) { actionString += "YES"; } else { actionString += "NO"; } String locationString = "key location: "; int location = e.getKeyLocation(); if (location == KeyEvent.KEY_LOCATION_STANDARD) { locationString += "standard"; } else if (location == KeyEvent.KEY_LOCATION_LEFT) { locationString += "left"; } else if (location == KeyEvent.KEY_LOCATION_RIGHT) { locationString += "right"; } else if (location == KeyEvent.KEY_LOCATION_NUMPAD) { locationString += "numpad"; } else { // (location == KeyEvent.KEY_LOCATION_UNKNOWN) locationString += "unknown"; } ...//Display information about the KeyEvent... } }
