title: How do I restrict keyboard focus to controls within a Node?
body: <p>I'm trying to implement a reusable method for displaying a node as a lightweight dialog. The node is added to the top of a StackPane while the background is then blurred. There are 2 problems:</p>
  
  <p>1) Controls in the background node of the stackpane are still able to receive focus.</p>
  
  <p>2) How do I give focus to the top-level node. I know there is a requestFocus method on Node, but I need to give it to a control nested within the node. Since this is intended to be a reusable method, I can't reference the controls directly.</p>
  
  <p>(if I can sidestep the whole problem by finding an existing implementation, that would be best, but I haven't found a 3rd party solution yet)</p>
  
  <p>Thanks</p>
