==Overview==
In [[Gambas]], a [[virtual class (Gambas)|virtual class]] is a class containing one or more [[virtual method]]s, i.e. methods whose [[method interface|interface]] has been defined but whose [[method implementation|implementation]] has not been. This is similar to the usage of the term in other languages.

In Gambas, virtual methods are always named beginning with a ".", e.g. ".ListViewItem".

It is not quite clear from the documentation, but it appears that virtual methods can only be [[virtual class instantiation|instantiated]] using C++; see [[writing classes in Gambas]].{{seed}}
