\membersection{wxCheckBox::wxCheckBox}\label{wxcheckboxconstr}

\func{}{wxCheckBox}{\void}

Default constructor.

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

Constructor, creating and showing a checkbox.

\wxheading{Parameters}

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

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

\docparam{label}{Text to be displayed next to the checkbox.}

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

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

\docparam{style}{Window style. See \helpref{wxCheckBox}{wxcheckbox}.}

\docparam{validator}{Window validator.}

\membersection{wxCheckBox::\destruct{wxCheckBox}}

\func{}{\destruct{wxCheckBox}}{\void}

Destructor, destroying the checkbox.

\membersection{wxCheckBox::Create}\label{wxcheckboxcreate}

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

Creates the checkbox for two-step construction. See \helpref{wxCheckBox::wxCheckBox}{wxcheckboxconstr}\rtfsp
for details.

\membersection{wxCheckBox::GetValue}\label{wxcheckboxgetvalue}

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

Gets the state of the checkbox.

\wxheading{Return value}

Returns {\tt true} if it is checked, {\tt false} otherwise.

\membersection{wxCheckBox::IsChecked}\label{wxcheckboxischecked}

\constfunc{bool}{IsChecked}{\void}

This is just a maybe more readable synonym for 
\helpref{GetValue}{wxcheckboxgetvalue}: just as the latter, it returns 
{\tt true} if the checkbox is checked and {\tt false} otherwise.

\membersection{wxCheckBox::SetValue}\label{wxcheckboxsetvalue}

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

Sets the checkbox to the given state. This does not cause a
wxEVT\_COMMAND\_CHECKBOX\_CLICKED event to get emitted.

\wxheading{Parameters}

\docparam{state}{If {\tt true}, the check is on, otherwise it is off.}
