\section{\class{wxCheckListBox}}\label{wxchecklistbox}

A checklistbox is like a listbox, but allows items to be checked or unchecked.

This class is currently implemented under Windows and GTK. When using this
class under Windows wxWidgets must be compiled with USE\_OWNER\_DRAWN set to 1.

Only the new functions for this class are documented; see also \helpref{wxListBox}{wxlistbox}.

Please note that wxCheckListBox uses client data in its implementation,
and therefore this is not available to the application.

\membersection{wxCheckListBox::wxCheckListBox}\label{wxchecklistboxctor}

\func{}{wxCheckListBox}{\void}

Default constructor.

\func{}{wxCheckListBox}{\param{wxWindow*}{ parent}, \param{wxWindowID}{ id},\rtfsp
\param{const wxPoint\&}{ pos = wxDefaultPosition}, \param{const wxSize\&}{ size = wxDefaultSize},\rtfsp
\param{int}{ n}, \param{const wxString }{choices[] = NULL},\rtfsp
\param{long}{ style = 0}, \param{const wxValidator\& }{validator = wxDefaultValidator}, \param{const wxString\& }{name = ``listBox"}}

\func{}{wxCheckListBox}{\param{wxWindow*}{ parent}, \param{wxWindowID}{ id},\rtfsp
\param{const wxPoint\&}{ pos}, \param{const wxSize\&}{ size},\rtfsp
\param{const wxArrayString\& }{choices},\rtfsp
\param{long}{ style = 0}, \param{const wxValidator\& }{validator = wxDefaultValidator}, \param{const wxString\& }{name = ``listBox"}}

Constructor, creating and showing a list box.

\wxheading{Parameters}

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

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

\docparam{pos}{Window position.}

\docparam{size}{Window size. If the default size (-1, -1) is specified then the window is sized
appropriately.}

\docparam{n}{Number of strings with which to initialise the control.}

\docparam{choices}{An array of strings with which to initialise the control.}

\docparam{style}{Window style. See \helpref{wxCheckListBox}{wxchecklistbox}.}

\docparam{validator}{Window validator.}

\docparam{name}{Window name.}

\pythonnote{The wxCheckListBox constructor in wxPython reduces the {\tt n}
and {\tt choices} arguments are to a single argument, which is
a list of strings.}

\perlnote{In wxPerl there is just an array reference in place of {\tt n}
and {\tt choices}.}

\membersection{wxCheckListBox::\destruct{wxCheckListBox}}\label{wxchecklistboxdtor}

\func{void}{\destruct{wxCheckListBox}}{\void}

Destructor, destroying the list box.

\membersection{wxCheckListBox::Check}\label{wxchecklistboxcheck}

\func{void}{Check}{\param{int }{item}, \param{bool}{ check = true}}

Checks the given item. Note that calling this method doesn't result in
wxEVT\_COMMAND\_CHECKLISTBOX\_TOGGLE being emitted.

\wxheading{Parameters}

\docparam{item}{Index of item to check.}

\docparam{check}{true if the item is to be checked, false otherwise.}

\membersection{wxCheckListBox::IsChecked}\label{wxchecklistboxischecked}

\constfunc{bool}{IsChecked}{\param{int}{ item}}

Returns true if the given item is checked, false otherwise.

\wxheading{Parameters}

\docparam{item}{Index of item whose check status is to be returned.}
