Building Creative Graphics Applications in JavaFX

The data flow UI is all custom.  A very early version tried to use the
NetBeans Visual Library, but we it didn't quite have do everything we
needed and we saw that Swing was on the way out so we went with FX.  At
first we embedded a JFXPanel in the Swing app.  Now it is all ported to
JavaFX though it can still run in a Swing mode with the JFXPanel.
The video processing is done with native code, but the data flow and
metadata that enables dynamic workflows is all on the Java side.  We had to
go native to get a decent video preview too, that's the most awkward part
of the UI.  There is no supported mechanism to even get the native window
handle of the stage so the preview window is a horrible hack.  I'm hoping
to get some support in FX to fix that - either access to a OpenGL or
DirectDraw context, or access to the MediaPlayer pipeline (my request for
that dates back to JavaFX 1.0).
