Eclipse 4 / SWT-JFace / JavaFX [message #1219343]

I've recently been investigating and experimenting with developing an Eclipse 4 application using JavaFX as the rendering engine. So far it has gone fairly well - I just started looking at E4 about a month ago. Now, I'm at a point where I'd like to mix JavaFX with SWT/JFace. The reason for this is that JavaFX does not currently have any notion of a dialog and I think I will need to use a JFace dialog to provide the dialog functionality and (hopefully) still use JavaFX to provide the dialog UI "content".

The trouble is: I can't figure out how to meld the two technologies together. I'm using eclipse Kepler along with e(fx)clipse. I followed a tutorial by Lars Vogel on developing an E4 RCP application and other tutorials on the e(fx)clipse site to incorporate JavaFX into E4. The target platform that I set up does not have any SWT or JFace libraries and I can't figure out how to get them and put them in. Should I go about it a different way?

I'm open to any suggestions as to how to solve these issues. I'd prefer to continue using E4 as the platform and JavaFX as the renderer. Any alternative approaches would be welcomed at this point.

You are not able embed SWT in JavaFX, only the other way is possible!

Having said that:
a) We BestSolution.at have an experimental port of SWT running on
JavaFX - see
http://tomsondev.bestsolution.at/2013/12/03/introducing-swt-on-fx/
b) Are really the JFace-Dialogs are the blocker? There are plenty of
external projects who provide JavaFX-Dialogs (including e(fx)clipse!)

If you have questions about JavaFX dialogs I'm happy to answer them at
the e(fx)clipse newsgroup.

Tom,

> You are not able embed SWT in JavaFX, only the other way is possible!

I must have worded it poorly. I'm not trying to embed SWT in JavaFX, but the reverse in order to have the SWT/JFace dialog behavior with the dialog's UI rendered via JavaFX. However, this may be moot considering the next item.

> b) Are really the JFace-Dialogs are the blocker? There are plenty of

Yes, this is the blocker for me at this point. I need to be able to display modal dialogs and I can't figure out how to do it with JavaFX. I tried to find examples where someone had implemented a dialog with JavaFX, but found very little that was helpful. I didn't think it could be done (without a little help from other technologies such as JFace). If you could point me to sources where this is being done, that would help considerably.

The problem is that then there 2 toolkits attached to the same event
loop. IIRC when you embed JavaFX in SWT, SWT has to be the one started
first which is not the case if you are launching an e4-fx application
where JavaFX comes first!

This is dead simple even to implement yourself but nothing we should
bother this list with because it is JavaFX/e(fx)clipse related.
