\func{void}{AddDependency}{\param{wxClassInfo * }{dep}}
\func{void}{AddDependency}{\param{const char * }{classname}}
Call this function from the constructor of the derived class. \arg{dep} must be
the \helpref{CLASSINFO}{classinfo} of a wxModule-derived class and the
corresponding module will be loaded \emph{before} and unloaded \emph{after}
this module.
The second version of this function allows a dependency to be added by
name without access to the class info. This is useful when a module is
declared entirely in a source file and there is no header for the declaration
of the module needed by \helpref{CLASSINFO}{classinfo}, however errors are
not detected until run-time, instead of compile-time, then.
Note that circular dependencies are detected and result in a fatal error.
\wxheading{Parameters}
\docparam{dep}{The class information object for the dependent module.}
\docparam{classname}{The class name of the dependent module.}
