Dear all.
I'm very new to Vtk and Tcl/Tk.
Now is my question how to  read or write the variables that are listed as 
protected in the class
reference of a function.
Simply use

        set val [planeWidgetX OriginalWindow]

Doesn't work.
Can someone also explain me what the purpose is of a protected variable.
Probably all very basic but I really don't know.

Thanks
Maurice
