\membersection{wxScopedPtr<T>::wxScopedPtr<T>}\label{wxscopedptrtemplatewxscopedptrtemplate}

\func{wxEXPLICIT}{wxScopedPtr<T>}{\param{T * }{ptr = NULL}}

Constructor.

\membersection{wxScopedPtr<T>::\destruct{wxScopedPtr<T>}}\label{wxscopedptrtemplatedtor}

\func{}{\destruct{wxScopedPtr<T>}}{\void}

Destructor.

\membersection{wxScopedPtr<T>::get}\label{wxscopedptrtemplateget}

\constfunc{T *}{get}{\void}

Returns pointer to object or NULL.

\membersection{wxScopedPtr<T>::operator unspecified\_bool\_type}\label{wxscopedptrtemplateoperatorbool}

\constfunc{}{operator unspecified\_bool\_type}{\void}

Conversion to a boolean expression (in a variant which is not 
convertable to anything but a boolean expression). If this class
contains a valid pointer it will return {\it true}, if it contains
a NULL pointer it will return {\it false}.

\membersection{wxScopedPtr<T>::operator*}\label{wxscopedptrtemplateoperatorreft}

\constfunc{T \&}{operator*}{\void}

Returns a reference to the object. If the internal pointer is NULL
this method will cause an assert in debug mode.

\membersection{wxScopedPtr<T>::operator->}\label{wxscopedptrtemplateoperatorderef}

\constfunc{T *}{operator->}{\void}

Returns pointer to object. If the pointer is NULL this method will 
cause an assert in debug mode.

\membersection{wxScopedPtr<T>::release}\label{wxscopedptrtemplaterelease}

\func{T*}{release}{\void}

Releases the current pointer and returns it.

\membersection{wxScopedPtr<T>::reset}\label{wxscopedptrtemplatereset}

\func{void}{reset}{\param{T * }{ptr = NULL}}

Reset pointer. Afterwards the caller is responsible for deleting
the data contained in the scoped pointer before.

\membersection{wxScopedPtr<T>::swap}\label{wxscopedptrtemplateswap}

\func{void}{swap}{\param{wxScopedPtr<T> \& }{ot}}

Swaps pointers.
