The problem is that you're not using the right kind of variable
Actually, aProperty is just a generic name for any sort of property
that one could declare. Sort of like myFoo.
If you declare relatedWindow as Window2 this would work
The problem is that I want something that is more generic for ANY
sort of Window. Not just a Window2 or Window3. I'm looking for
something that can be set to either a Window2 or Window3 or WindowX.
You can - a Window
BUT (as others have pointed out) this only gives you access to the
properties of an item that is of the Window Class and none of the
extra properties you added because they do not exist in a Window
They only exist in your new Window instances, which are both a
"Window" and maybe a "Window1", or "Window2" etc
In order to access those additional properties you have to know what
kind of Window it is and treat it as such
A property of that type OR a cast (as Charles and others pointe out)
is required
No magic required
