[news.eclipse.tools.gef] Re: Custom view and ... ??

Well, no probs, maybe U can answer my D&D question then :)


When I select element on my Editor selectionChanged() is called in View. 
This method is called because I've registered selection listener for my 
Custom View. Now I need data from selected object. Because I can't get 
data directly I'm using IAdaptable to do that. My EditPart implements 
IAdapatble and method getAdapter().



    public Object getAdapter(Class adapter)
        {
        if (adapter.equals(IGeneralProperties.class))
            {
            element = ((CallflowElement) getModel());

            return new GeneralProperties();
            }
        else
            return null;
        }


MyEditPart{ ...
private CallflowElement element = (CallflowElement) getModel();
private class GeneralProperties implements IGeneralProperties
        {
        //private CallflowElement element;


        public void setName(String name)
            {
            element.setName(name);
            }

 ...

        public String getName()
            {
            return element.getName();
            }

...
        }

...
}

I'm pasing object of GeneralProperties to a View, and it has 
implementation of getProp and setProp methods.

    protected void pageSelectionChanged(IWorkbenchPart part,
            ISelection selection)
        {
        StructuredSelection sel = (StructuredSelection) selection;

        if (sel.getFirstElement() instanceof IAdaptable)
            {
            if (sel.getFirstElement() instanceof CallflowEditPart)
                {
                IGeneralProperties prop = (IGeneralProperties) 
((IAdaptable) sel

.getFirstElement()).getAdapter(IGeneralProperties.class);
                _viewer.setGeneralProperties(prop);
                }
            }
        }

So in Viewer when somethings changed I can update Model properties.
That's it:)
