Felix,
As you are restricted in what you can say, that also restricts how I can
help. However, your example of a spreadsheet not being a control that
can be implemented in a scenegraph-based manner suggests that you might
want to re-evaluate your assumptions. A spreadsheet would be able to be
Though not directly analogous, consider your typical spreadsheet
application like Excel where the user is able to pan to the right
effectively without limits and that grid lines are constantly being
rendered as the panning takes place. Given that screens can be very large
these days it is

I'll have to check out the virtualisation that you refer to that's going on
in JavaFX8 with TableView., it sounds very interesting.
I am not saying that controls such as what I am proposing are *impossible*
to implement using a scenegraph; it just seems natural to implement
With all this talk of node virtualisation, I am wondering how feasible it
would to build some kind of automatic virtualiser such that you pass it
your real-world model and then it automagically works out the actual nodes
and pools required and manages them seamlessly to maximise rendering

I think it would pay to take a step back and understand why you think a
'traditional' scenegraph-based (or retained mode) control is not
sufficient for your needs?
Unfortunately you've not detailed your use case, so it is hard to give
any specific advice. Are you able to give any details about
Sneaking in here, as you've given an opening with if implemented wisely,
there is very little that a scenegraph-based approach can't do. The
question I've been asking for a while is what does implemented wisely
look like in JFX.
This has come up in the performance conversations, the game
I know Table uses a rubber stamp approach, where it re-uses cell views
where possible
One small correction -- this isn't what we call the rubber stamp (which is what
Swing did). The rubber stamp approach is to use a *single* cell and change its
state and reuse it for rendering everything
I don't think there is any particular secret sauce going on in what I do
compared with the general guidelines that have been spelled out numerous
times. It's the same old, same old: don't create more nodes than you
need, don't modify the scenegraph needlessly, don't update the
scenegraph
Thanks Jonathan, it's good to get your insight.
You did finish by muddying the waters again though - to do something
complex with zooming and scrolling you'd be tempted to fall back into
Java2D paint-style programming, and use Canvas for this, not the Scene
graph? It's more a couldbe/maybe
I only said that I'd consider using Canvas given my past experiences in
doing the same kind of thing in Java 2D, so I'm familiar with it in that
sense (but not in the real sense of having ever used Canvas in
production). If I were to ever implement something like this I would of
course be
To add
to the confusion, Canvas currently has some drastic z-order bugs, and some
clipping issues, so using it combined with Nodes is currently a no-go.
I believe those have all been fixed in the last couple of weeks.

It really wasn't ever supposed to be my TD game, I keep trying to get you (and
others interested in the community) to develop it. I'm up to my eyeballs in
work already, as I'm sure you can relate :-)

I'm big time behind on client work.
