How do you set a Class to be Virtual?
There is no built in way, but setting the constructors scope to
"private"
achieves that.
Hmm... I will have to try that.
Actually I think I figured out a method which achieves a similar
effect. The set of classes I am working with uses an Interface; and
so in the "virtual" class I have a this Interface method set to
Private and have an obnoxious MsgBox appear:
MsgBox "Programmer's Error: You must implement the function
MinimumWidthForStyle() defined in the XBarInterface. Please add
this function to your subclass with the Window instance with the name
of " + Me.Name + "."
The class is designed so that that particular method fires right at
launch, and so you only get embarrassed once. =)
