Re: [graphiti-dev] Graphiti and JavaFX
Hi Karsten,

thanks for providing more insight. I've tried out FXDiagram and I've seen GEF's first (small) steps towards JavaFX, but none of these efforts seem to be close to giving us a production-ready diagram editor based on JavaFX. When I asked my question on this mailing list, I wanted to get an impression for Graphiti's status quo, in order to complete my picture of JavaFX in the diagram editor world.

In summary, it seems like a long way to go, but thanks for giving me advice on good starting points.

Cheers,
Uwe

Hi Uwe,

you may ask also on the GEF forum, the GEF guys might have also an idea.

Further, at EclipseCon Europe, Jan Köhnlein presented an impressive JavaFX based editor draft. The repository for his example can be found at Github: https://github.com/JanKoehnlein/FXDiagram. Note that this project was just to demo his talk thesis about editors. It is unlikely that he will evolve it further.

To estimate the effort for the implementation of an alternative renderer the LOC of the underlying frameworks is totally misleading. These frameworks need deep knowledge on programming diagram editor frameworks. 

From my colleague Alexander Nyssen, project lead of GEF4, I know this is a long running task. He is working in long-term on an alternative GEF implementation, where JavaFX might be an alternative for the future. You may get also involved into GEF4. There have been already some proof-of-concept work on JavaFX support.
I would say, the best approach would be work on GEF4 JavaFX support, and then port Graphiti to use GEF4 instead of GEF(3).

Regards,
~Karsten

Hi Uwe,
 
not really. I’m new to JavaFX and not familiar with all concepts needed for a full port.
 
The org.eclipse.graphiti.ui plugin (which contains the GEF related parts) consists of about 20,000 lines of code (real code lines without comments and blank lines). Not sure if all of that would also be needed in JavaFX, but at least this might give a hint.

Michael

Hi Michael,

thanks for your reply and the reference to your Github repo. I'll check out your prototype.

Could you give a rough estimate of the amount of work required to implement a full JavaFX-based renderer? I'm relatively new to Graphiti and not too familiar with its inner workings. I have heard that the SWT renderer consists of about 25,000 lines of code.

Cheers,
Uwe

Hi Uwe, 

well maybe a small update? 

I also saw JavaFX gaining momentum und was able to play around a little, but due to lack of time did not get far. 

What I was able to start with is a small prototype of a rendering implementation for Graphiti in JavaFX. Currently it is able to render some simple diagrams (e.g. Chess example) in a view, but there is no interaction whatsoever. If you like to have a look I have it checked in to GitHub: 
https://github.com/mwenz/graphitiFX 

But still very basic stuff. Anyhow, if you are interested, any help here would be highly appreciated? 

Regards, 
Michael

Subject: [graphiti-dev] Graphiti and JavaFX 

Hi, 

more than 19 months ago, there was a short discussion about a JavaFX-based renderer on this mailing list, see http://dev.eclipse.org/mhonarc/lists/graphiti-dev/msg00079.html. The conclusion was that such a renderer would be a great thing to have, but there was no capacity for implementing it at the time. 

Are there any updates on this issue? 

I'm asking because JavaFX has gained a lot of momentum lately and I see many people adopt it. e(fx)clipse has done a good job in the Eclipse world in this regard. 

Thanks, 
Uwe
