\section{\class{wxClassInfo}}\label{wxclassinfo}

This class stores meta-information about classes. Instances of this class are
not generally defined directly by an application, but indirectly through use
of macros such as {\bf DECLARE\_DYNAMIC\_CLASS} and {\bf IMPLEMENT\_DYNAMIC\_CLASS}.

\membersection{wxClassInfo::wxClassInfo}\label{wxclassinfoctor}

\func{}{wxClassInfo}{\param{const wxChar * }{className}, \param{const wxClassInfo * }{baseClass1}, \param{const wxClassInfo * }{baseClass2},
 \param{int}{ size}, \param{wxObjectConstructorFn }{fn}}

Constructs a wxClassInfo object. The supplied macros implicitly construct objects of this
class, so there is no need to create such objects explicitly in an application.

\membersection{wxClassInfo::CreateObject}\label{wxclassinfocreateobject}

\constfunc{wxObject*}{CreateObject}{\void}

Creates an object of the appropriate kind. Returns NULL if the class has not been declared
dynamically creatable (typically, it is an abstract class).

\membersection{wxClassInfo::FindClass}\label{wxclassinfofindclass}

\func{static wxClassInfo *}{FindClass}{\param{wxChar * }{name}}

Finds the wxClassInfo object for a class of the given string name.

\membersection{wxClassInfo::GetBaseClassName1}\label{wxclassinfogetbaseclassname1}

\constfunc{wxChar *}{GetBaseClassName1}{\void}

Returns the name of the first base class (NULL if none).

\membersection{wxClassInfo::GetBaseClassName2}\label{wxclassinfogetbaseclassname2}

\constfunc{wxChar *}{GetBaseClassName2}{\void}

Returns the name of the second base class (NULL if none).

\membersection{wxClassInfo::GetClassName}\label{wxclassinfogetclassname}

\constfunc{wxChar *}{GetClassName}{\void}

Returns the string form of the class name.

\membersection{wxClassInfo::GetSize}\label{wxclassinfogetsize}

\constfunc{int}{GetSize}{\void}

Returns the size of the class.

\membersection{wxClassInfo::InitializeClasses}\label{wxclassinfoinitializeclasses}

\func{static void}{InitializeClasses}{\void}

Initializes pointers in the wxClassInfo objects for fast execution
of IsKindOf. Called in base wxWidgets library initialization.

\membersection{wxClassInfo::IsDynamic}\label{wxclassinfoisdynamic}

\constfunc{bool}{IsDynamic}{\void}

Returns true if this class info can create objects of the associated class.

\membersection{wxClassInfo::IsKindOf}\label{wxclassinfoiskindof}

\func{bool}{IsKindOf}{\param{wxClassInfo* }{info}}

Returns true if this class is a kind of (inherits from) the given class.
