\section{\class{wxSpinCtrl}}\label{wxspinctrl}

wxSpinCtrl combines \helpref{wxTextCtrl}{wxtextctrl} and 
\helpref{wxSpinButton}{wxspinbutton} in one control.

\helpref{wxControl}{wxcontrol}\\
\helpref{wxWindow}{wxwindow}\\
\helpref{wxEvtHandler}{wxevthandler}\\

\wxheading{Window styles}

\twocolwidtha{5cm}
\begin{twocollist}\itemsep=0pt
\twocolitem{\windowstyle{wxSP\_ARROW\_KEYS}}{The user can use arrow keys to change the value.}
\twocolitem{\windowstyle{wxSP\_WRAP}}{The value wraps at the minimum and maximum.}
\end{twocollist}

\wxheading{Event handling}

To process input from a spin button, use one of these event handler macros to direct input to member
functions that take a \helpref{wxSpinEvent}{wxspinevent} argument:

\twocolwidtha{7cm}
\begin{twocollist}\itemsep=0pt
\twocolitem{{\bf EVT\_SPINCTRL(id, func)}}{Generated whenever the numeric value
of the spinctrl is updated}
\end{twocollist}%

You may also use the \helpref{wxSpinButton}{wxspinbutton} event macros, however
the corresponding events will not be generated under all platforms. Finally, if
the user modifies the text in the edit part of the spin control directly, the
{\tt EVT\_TEXT} is generated, like for the \helpref{wxTextCtrl}{wxtextctrl}.

When the use enters text into the text area, the text is not
validated until the control loses focus (e.g. by using the TAB
key). The value is then adjusted to the range and a 
\helpref{wxSpinEvent}{wxspinevent} sent then if the value
is different from the last value sent.

\membersection{wxSpinCtrl::wxSpinCtrl}\label{wxspinctrlwxspinctrl}

\func{}{wxSpinCtrl}{\void}

Default constructor.

\func{}{wxSpinCtrl}{\param{wxWindow* }{parent}, \param{wxWindowID }{id = -1}, \param{const wxString\& }{value = wxEmptyString}, \param{const wxPoint\& }{pos = wxDefaultPosition}, \param{const wxSize\& }{size = wxDefaultSize}, \param{long }{style = wxSP\_ARROW\_KEYS}, \param{int }{min = 0}, \param{int }{max = 100}, \param{int }{initial = 0}, \param{const wxString\& }{name = \_T("wxSpinCtrl")}}

Constructor, creating and showing a spin control.

\wxheading{Parameters}

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

\docparam{value}{Default value.}

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

\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{wxSpinButton}{wxspinbutton}.}

\docparam{min}{Minimal value.}

\docparam{max}{Maximal value.}

\docparam{initial}{Initial value.}

\docparam{name}{Window name.}

\helpref{wxSpinCtrl::Create}{wxspinctrlcreate}

\membersection{wxSpinCtrl::Create}\label{wxspinctrlcreate}

\func{bool}{Create}{\param{wxWindow* }{parent}, \param{wxWindowID }{id = -1}, \param{const wxString\& }{value = wxEmptyString}, \param{const wxPoint\& }{pos = wxDefaultPosition}, \param{const wxSize\& }{size = wxDefaultSize}, \param{long }{style = wxSP\_ARROW\_KEYS}, \param{int }{min = 0}, \param{int }{max = 100}, \param{int }{initial = 0}, \param{const wxString\& }{name = \_T("wxSpinCtrl")}}

Creation function called by the spin control constructor.

See \helpref{wxSpinCtrl::wxSpinCtrl}{wxspinctrlwxspinctrl} for details.

\membersection{wxSpinCtrl::SetValue}\label{wxspinctrlsetvalue}

\func{void}{SetValue}{\param{const wxString\& }{text}}

\func{void}{SetValue}{\param{int }{value}}

Sets the value of the spin control.

\membersection{wxSpinCtrl::GetValue}\label{wxspinctrlgetvalue}

\constfunc{int}{GetValue}{\void}

Gets the value of the spin control.

\membersection{wxSpinCtrl::SetRange}\label{wxspinctrlsetrange}

\func{void}{SetRange}{\param{int }{minVal}, \param{int }{maxVal}}

Sets range of allowable values.

\membersection{wxSpinCtrl::SetSelection}\label{wxspinctrlsetselection}

\func{void}{SetSelection}{\param{long }{from}, \param{long }{to}}

Select the text in the text part of the control between  positions 
{\it from} (inclusive) and {\it to} (exclusive). This is similar to 
\helpref{wxTextCtrl::SetSelection}{wxtextctrlsetselection}.

{\bf NB:} this is currently only implemented for Windows and generic versions
of the control.

\membersection{wxSpinCtrl::GetMin}\label{wxspinctrlgetmin}

\constfunc{int}{GetMin}{\void}

Gets minimal allowable value.

\membersection{wxSpinCtrl::GetMax}\label{wxspinctrlgetmax}

\constfunc{int}{GetMax}{\void}

Gets maximal allowable value.
