Synchronization between Property Sheet and Tree View outline [message #206229]

Hello everyone,
I've followed this help
http://dev.eclipse.org/newslists/news.eclipse.modeling.gmf/m sg13295.html
to create a tree view outline and that works fine. However, I don't know
how to synchronize the property sheet and this tree view outline. In
details, The labels in the tree outline cannot reflect the change of
properties in the property sheet. And when I choose an item in the tree
view outline, the property sheet don't show the corresponding attributes
of the chosen class. Can anyone help me? Thanks in advance.
Toan.

labelProvider=" de.urszeidler.eclipse.callchain.diagram.sheet.CallchainSheet LabelProvider "

typeMapper=" de.urszeidler.eclipse.callchain.diagram.CallchainGMF2EMFType Mapper ">
<propertyCategory category="domain"/>
<propertyCategory category="visual"/>
<propertyCategory category="extra"/>
<propertyCategory category="advanced"/>
</propertyContributor>
</extension>

and a Typemapper :

package de.urszeidler.eclipse.callchain.diagram;

}
/**

*/
public static EObject adaptObject(Object object)
{
if (object == null)
{
return null;
}
else if (object instanceof EObject)
{
return (EObject) object;
}
else if (object instanceof IAdaptable)
{
// Try IAdaptable
IAdaptable adapted = (IAdaptable) object;
Object eObject = adapted.getAdapter(EObject.class);
if (eObject != null)

return (EObject) eObject;
}
}

// Try registered adapter

Platform.getAdapterManager().getAdapter(object, EObject.class);

Hi urs,
Thanks for your answer. I did it but I still don't have the
synchronization between the outline and the property sheet. Besides, when
applying this modification, I also lost the synchronization between the
property sheet and the view which I had before this modification. Can you
please guide me? Thanks.
Toan.

An alternative way would be to allow the property view to accept every
EObject in addition to View/Editpart/NavigatorItem.

I have changed the input template for gmfgen::TypeTabFilter in
/org.eclipse.gmf.codegen/templates/xpt/propsheet/extensions. xpt :

«DEFINE input FOR gmfgen::TypeTabFilter-»
«FOREACH getAllTypes() AS type-»
<input type="«type»"/>
«ENDFOREACH-»
«IF tab.sheet.editorGen.editor.useModelOrientedOutline-»
<input type="org.eclipse.emf.ecore.EObject"/>
«ENDIF-»
«ENDDEFINE»

Hi Enrico,
Thanks for your guidance. I'm sorry but I don't know where to modify
because I cannot find this
/org.eclipse.gmf.codegen/templates/xpt/propsheet/extensions. xpt in the
project.
But I think my problem is not only this because I did add <input
type="<myclass>" manually. And when I choose an Item in the tree outline,
the properties of this class can appear in property sheet but when I
modify these properties, this modification does not affect the label in
the tree view. So I think the problem is in the synchronization between
the tree view outline and the property sheet. Can you please help me?
Thanks.
Toan.

Hello Toan,

I don't know which part of our editor modifications do the trick, but it
works for us. We are using a lot of AOP for the modifications - I will have
to dig a bit deeper... maybe tomorrow.

What kind of property sheet do you use? I expected the tabbed property
sheet. Just like gmf generated one. And then this should work.
So perhaps in your tree viewer is a problem.

Does you mean that if you change a attribute part of the label, these
changes aren't displayed in the tree ?

greetings, urs.

Yes, I use the tabbed property sheet generated by gmf.

Yes, that's what exactly I mean.

I think the emf notification should work by default, so it's looks for
me that your current implantation (of the tree outline) contains an error.

greetings, urs.
