title: Remove Focus from JTextfields
body: <p>I have a <code>JDialog</code> with some <code>JTextfields</code>, and I want to remove the focus from the first textfield when I open the Dialog.</p>
  
  <p>I tried <code>.removeFocus()</code>, but then I can't use focus anymore. I just want to remove it, so  when I open the dialog no textfield is selected.</p>
