\section{\class{wxRadioButton}}\label{wxradiobutton}

A radio button item is a button which usually denotes one of several mutually
exclusive options. It has a text label next to a (usually) round button.

You can create a group of mutually-exclusive radio buttons by specifying {\tt wxRB\_GROUP} for
the first in the group. The group ends when another radio button group is created, or there are no more radio buttons.

\membersection{wxRadioButton::wxRadioButton}\label{wxradiobuttonctor}

\func{}{wxRadioButton}{\void}

Default constructor.

\func{}{wxRadioButton}{\param{wxWindow*}{ parent}, \param{wxWindowID}{ id}, \param{const wxString\& }{label},\rtfsp
\param{const wxPoint\& }{pos = wxDefaultPosition}, \param{const wxSize\&}{ size = wxDefaultSize},\rtfsp
\param{long}{ style = 0},\rtfsp
\param{const wxValidator\& }{validator = wxDefaultValidator},\rtfsp
\param{const wxString\& }{name = ``radioButton"}}

Constructor, creating and showing a radio button.

\wxheading{Parameters}

\docparam{parent}{Parent window. Must not be NULL.}

\docparam{id}{Window identifier. A value of -1 indicates a default value.}

\docparam{label}{Label for the radio button.}

\docparam{pos}{Window position. If the position (-1, -1) is specified then a default position is chosen.}

\docparam{size}{Window size. If the default size (-1, -1) is specified then a default size is chosen.}

\docparam{style}{Window style. See \helpref{wxRadioButton}{wxradiobutton}.}

\docparam{validator}{Window validator.}

\docparam{name}{Window name.}

\membersection{wxRadioButton::\destruct{wxRadioButton}}\label{wxradiobuttondtor}

\func{void}{\destruct{wxRadioButton}}{\void}

Destructor, destroying the radio button item.

\membersection{wxRadioButton::Create}\label{wxradiobuttoncreate}

\func{bool}{Create}{\param{wxWindow*}{ parent}, \param{wxWindowID}{ id}, \param{const wxString\& }{label},\rtfsp
\param{const wxPoint\& }{pos = wxDefaultPosition}, \param{const wxSize\&}{ size = wxDefaultSize},\rtfsp
\param{long}{ style = 0},\rtfsp
\param{const wxValidator\& }{validator = wxDefaultValidator},\rtfsp
\param{const wxString\& }{name = ``radioButton"}}

Creates the choice for two-step construction. See \helpref{wxRadioButton::wxRadioButton}{wxradiobuttonctor} for
further details.

\membersection{wxRadioButton::GetValue}\label{wxradiobuttongetvalue}

\constfunc{bool}{GetValue}{\void}

Returns true if the radio button is depressed, false otherwise.

\membersection{wxRadioButton::SetValue}\label{wxradiobuttonsetvalue}

\func{void}{SetValue}{\param{const bool}{ value}}

Sets the radio button to selected or deselected status. This does not cause a
wxEVT\_COMMAND\_RADIOBUTTON\_SELECTED event to get emitted.

\wxheading{Parameters}

\docparam{value}{true to select, false to deselect.}
