Hello,

I'm starting with JFace,i have a treeView which is used as menu, i need to associate some part with each children node. When we doubleclick on the node it should open associated part

how could I, determine which part is associated with a given node, i dont have access to content model, to get the part Id

How should I proceed?

viewer.addDoubleClickListener(new IDoubleClickListener() {
		    	
  @Override
   public void doubleClick(DoubleClickEvent event) {
	TreeViewer viewer = (TreeViewer) event.getViewer();
	IStructuredSelection thisSelection = (IStructuredSelection) event
		            .getSelection();
		        
	 Object selectedNode = thisSelection.getFirstElement();
	  
           //TODO somthing with selectedNode 
		        
		        
		        
		       
		        
		      }
		    });

thank's

I solved my problem, finally the node is an instance of my object model, it was enough to cast the Selected node to my model object, like this

if (selectedNode instanceof NavigatorMenuItem) {
      NavigatorMenuItem o = (NavigatorMenuItem) selectedNode;
		        
       System.out.println(o.getItemLibelle()) ;  	   
		        	   
		         
		        }
