Hi David,
I have stylesheet SWITCHING working fine. I can switch between 2 different
stylesheets on disk without tearing down & rebuilding my Scene. To do this
I simply do:
scene.stylesheets.clear()
scene.stylesheets.add(differentStylesheet)
and the changes show up immediately (I'm assuming those 2 lines cause a
.css recalculation & a pulse).
I would like to get stylesheet RELOADING to work in my JavaFX 8 app. By
this I mean picking up changes in a single .css file. This would allow the
developers to tweak the stylesheet & reload to see the effects
immediately.
Unfortunately, it feels like the Filename of the stylesheet is the Key in
a cache that isn't getting cleared by my code above. Nothing visible
happens when I do:
scene.stylesheets.clear()
scene.stylesheets.add(sameStylesheet)
Given your description below, my impression is that RELOADING should also
work...
Thank you for any suggestions,
Neil

The way it works in 8.0 is that there is a cache of loaded stylesheets.
When a scene or parent adds a stylesheet, the stylesheet is added to the
cache. Any other scene or parent that uses the same stylesheet will get
the one from cache. If a scene or parent later removes the stylesheet, the
stylesheet is removed from the cache and the css style cache for any scene
or parent that referenced that stylesheet is cleared (since the set of
styles may have changed). Any scene or parent that referenced the now
removed stylesheet is told to reapply its styles. Since the stylesheet is
no longer in cache, it will be re-parsed (or reloaded if there is a binary
version of the stylesheet) when it is called for by a scene or parent.
The way it worked in 2.x was an abomination.
