[EEF] Custom Toolkit Widgets [message #540684]

I have created a custom combo viewer control and I would like to use it as a custom toolkit widget for one of my properties. Is it possible to extend the code generator to use my custom widget? I created a custom.toolkit model and added my custom widget to it. I then linked to it from my *.components file. When I generate the EEF architecture the code generator throws an error when I get to the custom widget. I think it is because there is no code template for my custom widget. Is there a way to add a dynamic code generation template so my widget will be generated?

Hi mike,

you have done the first part of the job.

We are writing a wiki page that will explain in details what you have to
do.
the difficult part is that you hve to create a new Acceleo generator
project and extends some of the templates with guards that are compliant
with your widget.

Sorry for the delay,

Stephane

I'm also interested in adding some custom widgets. Is this wiki page complete yet? If so, please post a link to it.

Thanks,
Josh

Hi Josh,

Unfortunately we didn't have time to progress on that tutorial. We hope to make it available very soon.

This isn't that hard actually.
You create a plug-in that has the acceleo nature.
You then have to code 4 templates for each widget.
You'll find the templates to override in org.eclipse.emf.eef.codegen.widgets.api.
The best solution is to take as exemple the existing widgets.

Once you've done that you have to use the 'org.eclipse.acceleo.engine.dynamic.templates' extension point on your plug-in and add as templates the path of the templates you defined.

The plug-in has to be loaded to be used at the generation time so you can't have it in the same workspace as your EEF project I guess. Either you have to export it in a jar format or you launch a dynamic eclipse instance and generate your EEF project in this new workspace.
