Getting the name of a class when right clicking [message #645277]

Hi,

I've added a context menu entry in Eclipse when right clicking an object (maybe a class) and then an action is run. I get a selection array into the run method in the action but I've no idea on how to get the name of the class, what I get is an object of the type ClassEditPart. Does anyone have an idea on how to get the name of the object in question?

I've been digging around and haven't found a solution yet. Does anyone know if there's any way to get an object of type ClassImpl from an object of type ClassEditPart?

So.. i don't have solution but I know how to search for it.
I think that ClassImpl is object representing model and class edit part is a class representing view. As I know this class have public method getUmlElement(). Try to view this class or dig in debugger.

How you did this?

Hi, thanks for your reply. I eventually found out how to do this with this code (so many lines for such a simple task!):

GraphicalEditPart editPart = (GraphicalEditPart) selections[0];
ShapeImpl item = (ShapeImpl) editPart.getModel();
EObject obj = item.getElement();
EStructuralFeature namefeature = obj.eClass().getEStructuralFeature("name");
String name = (String) obj.eGet(namefeature);

You mentioned the context menu, I added it with this code to the plugin.xml:

   <extension point = "org.eclipse.ui.popupMenus">
      <viewerContribution
        id="<path to action>"
        targetID="org.eclipse.gmf.runtime.diagram.ui.DiagramEditorContextMenu">
	    <action id="<action id>"
	       label="<label>"
	       menubarPath="additions"
           definitionId="<id>"
	       class="<path to class>">	
	    </action>
       </viewerContribution>
	 </extension>

I now have a new problem to address, that is how to find the path to the file which was right-clicked. It seems that every simple task has to be very complicated when working with plugins in Eclipse. I will add a new thread on it though.
