\class ModNullCallback
|
|
\brief ModNullCallback is a class containing all the callback
|
|
functions for this demonstartion module. These functions are
|
|
added into the standard Audacity Project Menus.

\class ModNullCommandFunctor
|
|
\brief We create one of these functors for each menu item or
|
|
command which we register with the Command Manager. These take the
|
|
click from the menu into the actual function to be called.
