I'd like to use a Clutter stage as a widget in an SWT window. I'm aware that there are Java bindings for Clutter, but I'm not sure how to use them (for SWT or otherwise).
I suspect that this might be a bit difficult. If it's prohibitively difficult, then I would appreciate some possible alternatives. However, upon searching, the only alternative to Clutter I could find was Core Animation from Apple (which isn't for Java, obviously). So, the ideal solution would be to get Clutter to work for SWT.
Have you tried JavaFX as an alternative? There is an article here: http://www.sooperarticles.com/technology-articles/operating-system-articles/integration-swing-swt-javafx-2-0-899116.html ,which explains how you can use JavaFX with SWT or Swing.
JavaFX is possibly the closest to Clutter you can get in the Javaworld, without using Clutter.
I have never used the Clutter Java bindings but I suspect that it would not be a trivial task to combine Clutter and SWT.
