Public way to monitor JavaFX Windows

[Matthieu BROUILLARD]

Hi all,

I'd like to know if there is a public way to monitor all "root" window
JavaFX objects (Window, Stage, PopupWindow).

All what I have found until now is "private impl"

   - com.sun.javafx.stage.StageHelper.getStages(), observable but relevant
   only for Stages
   - javafx.stage.Window.impl_getWindows(), used inside ScenicView but not
   listenable

If there is not a public API, I'll create a JIRA for this.
