Hi.
This should be the same code to disable the button, but sometimes
For example, if I delete all the text the button doesn't disable

 void jTextField1_keyPressed(KeyEvent e) {
    if (jTextField1.getText().length() > 0) {
      jButton1.setEnabled(true);
    }
    else {
      jButton1.setEnabled(false);
    }
  }

Thanks
