This is the base class for a control or ``widget''.

A control is generally a small window which processes user input and/or
displays one or more item of data.

\membersection{wxControl::Command}\label{wxcontrolcommand}

\func{void}{Command}{\param{wxCommandEvent\& }{event}}

Simulates the effect of the user issuing a command to the item. See \helpref{wxCommandEvent}{wxcommandevent}.


\membersection{wxControl::GetLabel}\label{wxcontrolgetlabel}

\constfunc{const wxString\&}{GetLabel}{\void}

Returns the control's text.

Note that the returned string contains the mnemonics (\texttt{\&} characters) if
any, use \helpref{wxControl::GetLabelText}{wxcontrolgetlabeltext} if they are
undesired.


\membersection{wxControl::GetLabelText}\label{wxcontrolgetlabeltext}

\constfunc{const wxString\&}{GetLabelText}{\void}

\func{static const wxString\&}{GetLabelText}{\param{const wxString\& }{label}}

Returns the control's label or the given \arg{label} string for the static
version without the mnemonics characters.


\membersection{wxControl::SetLabel}\label{wxcontrolsetlabel}

\func{void}{SetLabel}{\param{const wxString\& }{label}}

Sets the item's text.

The \texttt{\&} characters in the \arg{label} are special and indicate that the
following character is a mnemonic for this control and can be used to activate
it from the keyboard (typically by using \textit{Alt} key in combination with
it). To insert a literal ampersand character, you need to double it, i.e. use 
\texttt{"\&\&"}.
