Disabling pasting in JTextField

Question

I have a JTextField that has a KeyListener that prevents people from typing in certain characters. For instance, one of them only accepts numbers. It works fine, but if I copy and paste text to it (using Ctrl-v) the text pastes and the KeyEvent is never fired. SO I end up with some text like "Jun" in a JTextArea that only allows numbers. Is there a way to disable pasting on a JTextField

Answer 1

I've seldom used KeyListener, wherever I can, I use the component's processkeybind. The following snippet of code will trap CTRL-V before the component received it:
   JTextField myTextField = new JTextField() {
      public boolean processKeyBinding(KeyStroke ks, KeyEvent e, int condition, boolean pressed) {
         if (ks == KeyStroke.getKeyStroke(KeyEvent.KeyEvent.VK_V,2)) return true;
         return super.processKeyBinding(ks,e,condition,pressed);
   };;o)
