I'm still new to D too, but I think it works in this scenario 
because private in D works on the module/file level. 
main/TestRigWindow/MyButton are defined in the same file (module) 
and thus can access each others private members. If you put the 
button class in its own file/module and import it then you would 
have to make its constructor public to access it.
