Creating a custom JFace based extension [message #1777229]

Hello everyone,

I am trying to create a custom extension to make a jface.Viewer based implementation testable through Jubula. This component basically uses all the benefits of the jface.Viewer API and combines it with a simple Canvas, on which I do some rendering (drawing lines, etc.). I'd like to make this custom component being testable with Jubula.

I have a plug-in implementing the the toolkit extension, where I define my IToolkitProvider.
It also contains the ComponentConfiguration.xml, which looks like:

    <toolkitComponent type="country.company.project.MyViewer" visible="true">
        <realizes>org.eclipse.jface.viewers.Viewer</realizes>
        <testerClass>some.package.MyViewerTester</testerClass>        
        <action name="UserExtension.rcverifytest">
            <method>rcverifytest</method>
            <param name="UserExtension.rcverifytest.test">
                <type>java.lang.String</type>
            </param>
        </action>
    </toolkitComponent>

Is it correct to use the "realizes" tag along with the base/parent class of my custom implementation?

To establish my Adapter and Factory I created a fragment bundle, which contains both: Adapter and AdapterFactory.
The package I used is: org.eclipse.jubula.ext.rc.common.adapter

My Factory looks like:

public class GraphViewerAdapterFactory implements IAdapterFactory {

private static final Class[] ADAPTABLE_TYPES = new Class[]{
MyViewer.class
};

@SuppressWarnings("unchecked")
@Override
public Object getAdapter(Class adaptableType, Object adaptableObject) {
if (adaptableType.isAssignableFrom(IComponent.class)){
return new MyViewerAdapter(adaptableObject);
}
return null;
}

@Override
public Class[] getSupportedClasses() {
return ADAPTABLE_TYPES;
}
}

In the adapter itself I simply cast the parameter (adaptableObject) to MyViewer and redirect all the calls from
the base class AbstractComponentAdapter/interface IWidgetComponent.

These two bundles are referenced by a feature bundle, which is part of an updatesite, which can be used to install the extension.
But the part in the documentation "3.4 Addressing custom controls via the client" is beyond my comprehension.
Where do I put the org.eclipse.jubula.toolkit.ToolkitInfo Implementation?
Where do I put my org.eclipse.jubula.client.AUTAgent extends Remote Implementation? Is there an extension point I am missing? And what is a CAPBuilder?

Thanks for taking the time to read this post.

Hello Gilles,

The Component Configuration seems to be a little bit wrong. We have two things which we must keep in mind. First of all JFace component wrap most of the time a normal SWT component. So Jubula could only map the SWT component. Secondly, the realizes is the name of our internal Component names. Since you are writing a new component which is not a e.g. list or other component we have functionality for you use there "guidancer.abstract.Widget".
The rest of your implementations looks good.

With your last questions. I think you are mixing up extensions for API and for Jubula itself.[1] The chapter you are describing is only for the jubula API if you want to write test in Java.

with regards

Hello Gilles,
I am looking to do a very similar thing to what you have described in this post. I was wondering if you managed to get any further with this or not. Happy to share any help/thoughts on this to try to find a resolution. Thanks
Regards,
Stuart.

Hi Stuart,

I have adopted the proposed changes from Marvin, but wasn't able to see my extension in action yet.

IMHO a correct(er) ComponentConfiguration.xml would look like this

<toolkitComponent type="country.company.project.MyViewerForITETypeSystem" visible="true">
        <realizes>guidancer.abstract.Widget</realizes>
        <componentClass>exact.fqn.of.instance.at.runtime.in.aut.context</componentClass > <!-- e.g. the Canvas --> 
        <testerClass>some.package.MyViewerTester</testerClass>        
        <action name="UserExtension.rcVerifyTest">
            <method>rcVerifyTest</method>
            <param name="UserExtension.rcVerifyTest.test">
                <type>java.lang.String</type>
            </param>
        </action>
    </toolkitComponent>
