title: Embed JavaFX Stage inside JFXPanel (Swing Embed)
body: <p>I'm trying to modify an existing JavaFX GUI program to have a feature of "Always Stay On Top". This is not supported in JavaFX at the moment (why!?!?), so some googling has led me to believe I must marry Swing into my JavaFX application in order to achieve this. Not ideal, but OK.</p>
  
  <p>All example patterns I've found use the <code>JFXPanel</code> instead of <code>Stage</code>, however since my application already exists and was written using JavaFX from the start (zero Swing is in the codebase at the moment), removing the <code>Stage</code> from the application starts to become a major re-write just to support this "on top" feature.</p>
  
  <p>How can I embed an existing JavaFX <code>Stage</code> in a <code>JFXPanel</code> or similar, that will allow me to use the standard <code>getSomeSwingWindowOrPanel().setAlwaysOnTop(true);</code> and make my application float on top of all other windows as expected? Am I going about this wrong, ie. is there a better way such as using JNI or something?</p>
