Hi,

Having generated an EMF model & editor code, I want to create my own page/view and add some controls to it (combo boxes, groups, etc). How should I go about this please? My attempt is shown below, but clearly doesn't work - best I can manage is the display of one combo filling the entire view.

Do I need to create something like a view part (which I've done and laid out all my controls nicely - it's just not connected with my EMF code at all)? If it is a view part how do I link it to the EMF code (if not in createPages())?

All clues, hints, help appreciated.

Thanks,
Greg

This is more a question of how to create views using JFace, not an
EMF-specific question. To have a view with multiple things on it, you'd
need a Composite and using layouts https://wiki.eclipse.org/JFaceSnippets

You'll want to use data binding to bind something more specific than the
whole editing domain.

I imagine this must thrown an exception given EClass (the third
argument) isn't an EStructuralFeature. You'll want to obverse some
value you get from the resource in the resource set, and you'll want to
specify a feature that value actually has.

Have a look at WindowBuilder.
