[Gambas-user] How to use a virtual class in gambas

[Brian G]

Thanks for your reply Christof and no I did not know about our search engine!

Ok After reading from the thread, and searching for other Ref. I see in my understanding that 
unless I am writing C++ there is in fact no real virtual class[interface] to underlying classes/Object.

I looked into the ARRAY class and see that the .Array.Bounds class is used a 

GB_PROPERTY_SELF for that object .

I am trying to create a class which inherits array cant seem to get the bounds working... 

Am I missing something.. or is there actually a way to use virtual gambas classes.

Maybe I don't understand how to link the virtual object to the underlying real object. and return 
it from a call to a read property.

I am trying to keep everything in Gambas itself.

Thank You
Brian G
