[EEF] Custom Toolkit Widgets [message #622996]

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.

Hi Joshua, Could you share the plugin with your custom widgets?
(I am interrested in the codegen templates you use, and how you hook
them for your widget).

Thanks Christophe

Hi all,

I know that this topic is a bit old but I'm facing the same problem, so I hope someone could give a solution Smile

I'm trying to add a custom SWT Widget in the EEF generation process. So thanks to the previous message, I managed to create a .toolkits model in which I added my widget. Then I loaded this resource in the .components model and I am now able to select my widget in the representation field.

I also coded the 4 templates (xxControl, xxGettersSetters, xxSWTImpl, xxFormImpl), taking example on org.eclipse.emf.eef.codegen.widgets.impl.text templates.

But when I try to generate the project code thanks to my .eefgen model, some errors raise and I am not able to produce what I want.

Error: Problem while Organize Imports : project_path.edit/src-gen/class_using_my_widget.java

In the generated code there are many messages like:

xxPropertiesEditionPart.java :

public //FIXME ERROR INVALID CASE INTO template public toJavaType(view : ViewElement) in common.mtl module for representation EMigPropertyEditor getValue();

public void setValue(//FIXME ERROR INVALID CASE INTO template public toJavaType(view : ViewElement) in common.mtl module for representation EMigPropertyEditor newValue);

xxPropertiesEditionPartForm.java :

//FIXME INVALID CASE INTO template public widgetDeclaration(editor : ElementEditor) in viewFormUtils.mtl module

//FIXME INVALID CASE INTO template public implementation(editor : ViewElement, pec : PropertiesEditionComponent) in viewUtils.mtl module

So if someone has any idea ...

Thanks in advance

It seems to be due to the statements defined in org.eclipse.emf.eef.codegen.services.common.mtl, so I decided to overrides the behavior of the template toJavaType(view : ViewElement).
I added the Java object corresponding to my view (a String) and when I start a new instance of Eclipse with my plug-ins, the EEF generation process works well.

Then I decided to package my set of plug-in thanks to an ANT task, and I tried to used acceleoCompiler task in order to compile my *.mtl modules.

But I have got several errors due to the fact that EEF modules are not found in my tasks:

Quote:

acceleo.compile:
[acceleoCompiler] commonExtension.mtl
[acceleoCompiler] 2:Module org::eclipse::emf::eef::codegen::services::common not found.
...

I don't know why modules are not found during the compilation, I added the following .jar in my ANT classpath configuration:

org.eclipse.acceleo.common
org.eclipse.acceleo.model
org.eclipse.acceleo.parser
org.eclipse.core.runtime
org.eclipse.emf.ecore
org.eclipse.emf.ecore.xmi
org.eclipse.ocl
org.eclipse.ocl.ecore
org.eclipse.emf.eef.codegen => this one containes acceleo modules I'd like to extend.

I hope someone could help me and if I find the solution I'll post it there.

Thanks in advance,

Aurélien

Hi Aurelien,

The support for Ant in Acceleo has been improved for Acceleo 3.1.0 M7 that will be released soon. If you want to build your project with Ant you should take example on the new version of the generation task.

You should just have to replace the call to the "Generate.java" class to a call to the Acceleo compiler with your parameters.

If you want to build with the existing Ant task to deploy an Acceleo generator, you can just let Eclipse do the job, it will call the Ant task to compile with the AcceleoCompiler. In order to do that: blog

In any way, make sure that you are using the latest release of Acceleo from the Acceleo update site since we have improved the Ant compilation in the 3.0.2 release:
3.0.x -> http://download.eclipse.org/modeling/m2t/acceleo/updates/rel eases/3.0

Or you could try the latest nightly build of Acceleo 3.1 here:
3.1 -> http://download.eclipse.org/modeling/m2t/acceleo/updates/nig htly/3.1

Hi Stephane,

Thanks for your help, I will try to compile thanks to this example.

Hello,

I know the post is kind of old but I really hope to get some answers.

I would like to know if the wiki page that is mentioned above will be available soon. I need to have an editable Combo viewer for my EEF editor and I don't even know where to start.

Mike Morell said "I have created a custom combo viewer control" and "I created a custom.toolkit model and added my custom widget to it", does anyone know which steps to follow to do that?

Thank you.
