I'm sorry this thread scrolled away into the bitbucket in the sky.

Last JavaOne, we wrote a prototype that showed native integration on OS X. We parented a native sheet dialog in an FX stage and providing an OpenGL node. The code was a prototype that worked only on OS X. The Open GL node allowed drawing JOGL and LWJGL to draw on a texture that was created by FX. This mean that the OpenGL node could take part in FX animations and effects.

I will attach the prototype code to https://javafx-jira.kenai.com/browse/RT-36215. I need to find it and make sure that it still compiles and works. This week is M5 RDP2 and today is likely to be a write off for a number of reasons.


Please ping me in the JIRA if the code doesn't show up sometime this week. The prototype is the basis of one possible implementation and needs some work. There are other possible implementations and this is not the final word on the issue.

Sorry, my last reply did not go to the list. That was unintended.

Oracle-Team, please someone comment on this, at least on what should
be done regarding a Jira Issue (or several ones?) to track any
progress on this and collect ideas & requirements.

Best regards,

Thanks for the hint. I think this is similar to what a colleague of
mine did a while ago as a proof of concept using other com.sun.api
that then went away. As long as we're bundling the JRE with our
product and we're desperate enough to get it working, we might do
something like this but it's of course just a last resort. Lets hope
someone from Oracle says something.

That’s basically it. It isn’t perfect, but its so simple I don’t see why it

That said, com.sun.glass.ui.Window contains the field we want:

     // Native object handle (HWND, or NSWindow*, etc.)
     long ptr;

You could be evil and hack it now with reflection, but it relies on internal 
implementation details.

In my application I already create a native window for video preview… though 
not as a child of the FX window.  The problem is that there isn’t a 
straight-forward, reliable, supported way to get the window handle to use for 
the parent (JavaFX) window.  There are ways to hack it, but they aren’t pretty.

Just for my understanding: Your approach would be to get the native
window handle for the hosting JFX stage, then leave an open space in
the layout for e.g. the player canvas that will be implemented
natively and then create a native child window that just reacts to
move and resize events of its native parent?

This is critical, but I don't think we need to focus on a specific technology 
like Direct3D or OpenGL. As a first step all we need is a mechanism to get a 
native reference to the Window. Just like we can with JAWT.  I'm guessing that 
JavaFX doesn't use heavyweight child windows so we could add a new child window 
that we manage with our own code and it would appear on top of the JavaFX

I absolutely agree that such a feature is critical for the success and
longevity of JavaFX.  I am *really* hoping for some heavily beefed-up 3D
support in a JFX 8.* release or JFX 9.

I need my graphics toolkit (currently JavaFX) to be able to handle
everything from simple UIs with basic controls to complex 3D
visualisations, just like the underlying graphics API is capable of (i.e.
OpenGL or Direct3D).  I strongly suspect though that focusing on OpenGL
exclusively is the only viable way to go from a cost perspective which
would mean JavaFX supporting OpenGL on Windows.

it has been discussed a number of time in the passed but let me
quickly summarize:

A number of people have requested a feature that provides the ability
to have native code draw into a surface provided by a JavaFX
application as fast as technically possible, i.e. with no indirection
or copying because use cases for this were mostly cases where
performance was critical, e.g. HD/UHD video players, real-time
visualization etc. where losing even e few percent would make a
software written in JavaFX unable to compete with native products
(e.g. in the video area nobody will use a video player that is not
able to play the content smoothly that VLC player or Quicktime can on
the same machine). Some people already have libraries of native code
that they have built over the years and would like to reuse. I would
even go so far to say that our product will probably never be able to
move to JFX (apart from mixing it a bit with Swing, which we currently
see rather aa a migration strategy and not as the end result) without
this problem solved.

In the past the reactions/signals from the Oracle team in this respect
were mixed but some of it indicated that this topic was discussed in
the past and might be revisited after the release of JFX 8. Now that
the latter has happened I would like to ask what the plans for this

Is there a Jira Issue where we can track the progress of it?

If not, does it make sense if I open one, so people (probably the same
ones that have participated in these discussions in the past like
Scott and the Ultramixer guys etc.) can collect their

Even if Oracle should decide not to do something about it, it would
still be nice to get pointers in the code base to where this would be
possible, even if it is non-portable. I know that for our product it
would be totally OK to have different ways of doing this for each
platform and to live with the limitation to not be able to manipulate
the result in the FX scene graph apart from that the position of the
surface moving with the hosting FX node and as far as I have
understood others, it is the same for them.

Maybe a Jira issue could also be a good place to bundle information
about approaches interested parties are willing to pursue.

Thoughts anyone?
