Hi guys,

I'm currently trying to add a behavioral extension implemented using a
content adapter to a model managed by XText.

I already managed to achieve it in an EMF.Edit generated editor and I'm
looking around the TMF XText generated editor to find a place where to
attach my adaptor.

I would be most greatfull if you could point me to the right place in
the generated code.

Kind Regards,

Cédric Vidal

PS: I'm using TMF Xtext 0.7RC2 bundle from Itemis

Ok,

I found out the following solution. I subclassed XtextEditor:

public class MyXtextEditor extends XtextEditor {

@Override
public void createPartControl(Composite parent) {
super.createPartControl(parent);
IXtextDocument document = getDocument();

document.modify(new IUnitOfWork<Object, XtextResource>() {
@Override
public Object exec(XtextResource resource) throws Exception {
attachBehavior(resource);
return null;
}
});

document.addModelListener(new IXtextModelListener() {
@Override
public void modelChanged(XtextResource resource) {
attachBehavior(resource);
}
});
}

private void attachBehavior(XtextResource resource) {
// attach adaptor
}

}

and changed plugin.xml editor configuration to use mine instead of
default XtextEditor.

So far it works for me.

Kind regards,

Cédric

As the editor usually is created by guice, there might be some component
declaring a dependency on XtextEditor. You should change the
configuration in the ui module instead of changing the contents of
plugin.xml. We might inject the editor somewhere else.

To do so add a binding like this:

public class MyLanguageUiModule extends AbstractMyLanguageUiModule {

public Class<? extends XtextEditor> bindEditor() {
return MySpecialEditor.class;
}

.....

Cheers,
Sven

Hi Sven,

Thanx for the correction. I'll try that as soon as I get the chance.

Regards,

Cédric
