remove focus from TextField JavaFX
<p>I can not remove focus from the <code>TextField</code>. On my view I only have one editable content: Text in a <code>TextField</code>. The problem is that as a user one never gets rid of the focus (because there is nothing else to focus on), once the <code>TextField</code> is focused. I want to remove the focus from the <code>TextField</code>. </p>
