I'm so pleased to see you're eager to get your work contributed back to
OpenJFX. I hope this is the beginning of a number of contributions
being made back to the OpenJFX project from people.
There is a process that needs to be worked through from having an idea
(or initial code drop) to seeing it appear in a future JavaFX release.
The early parts of this process are well-defined, but we're still
working on defining the entire process.
The first step is that you need to sign the Oracle Contributor
Agreement, if you haven't already. You can find the website and form at
. I am not a lawyer of any description, but the basic premise is
that you need to have the legal right to contribute the code you want
The UI controls team has a member whose fulltime job is developing what
we call UX specifications (UX = User Experience). Essentially these
documents cover the functional expectations for every UI control, and
normally includes descriptions of each function, diagrams detailing
user interaction expectations, and details on mouse and keyboard input
requirements / shortcuts. In the case of the calendar picker and
spinner controls, we already have these UX specifications written up.
Hopefully we'll be able to make these documents available soon, so that
you (and others) may refer to them in implementing your controls. As
you can probably imagine, these documents are wonderfully detailed and
often open your eyes to functionality that you'd never even considered
(and it is much better to consider it earlier in the process rather
than after the control has shipped!).
There is a lot of work that goes into a control, outside of
engineering. In particular, we have an SQE team who write tests
(normally at a higher functional level - based largely on the UX
specifications). Writing and running these tests takes time, and for
JavaFX 2.1 we're already committed to what engineering can develop, and
what SQE can test. There are plans afoot to getting more of the SQE
testing infrastructure open sourced so that external developers can
both run and write their own functional tests, but again we're not
quite there yet. What this means is that the calendar and spinner
controls won't be able to be included in JavaFX 2.1, but can certainly
be considered for inclusion in future releases.
Our plan is to open an incubator mercurial repo soon, that will be able
to facilitate the development of this code before it finds a home in
the OpenJFX repo itself. Once the code is in this repo, I'd like to
offer to help you with these controls, so that we may get them
developed to a point where they can appear in a future release of
The other thing you may want to get started on is discussing the API
design and seeking feedback. The openjfx-dev mailing list is certainly
the best place for this discussion to take place, and I look forward to
hearing about it.
Thanks for being so keen to help fill in the gaps!
