I'm looking for a way to use a drop-down (Combo) control in EMF Forms, using a list of strings that can be replaced at runtime, rather than using eenums. In looking at modifying/extending existing renderers, I'm not clear on a good approach. Any ideas/suggestions?

Regards,
Sven

Hi Sven,

did you read this article? https://eclipsesource.com/blogs/tutorials/how-to-customize-emf-forms/
The best starting point would probably be org.eclipse.emf.ecp.view.internal.core.swt.renderer.EnumComboViewerSWTRenderer . And as you don't have enums, just subclass org.eclipse.emf.ecp.view.spi.core.swt.SimpleControlJFaceViewerSWTRenderer and implement the methods similar to how it is done in the enumrenderer.

If you need more detailed information. Let me know.

Best,
Eugen

Hi Eugen,

Yes, I read the article and tried something along the line of your suggestion, didn't get it to work. Will take a second and let you know if I need more detail.

Thanks,
Sven
