Unlike \helpref{wxCalendarCtrl}{wxcalendarctrl}, which is a relatively big control, wxDatePickerCtrl is implemented as a small window showing the currently selected date. The control can be edited using the keyboard, and can also display a popup window for more user-friendly date selection, depending on the styles used and the platform. It is only available if \texttt{wxUSE\_DATEPICKCTRL} is set to $1$. \wxheading{Derived from} \helpref{wxControl}{wxcontrol}\\ \helpref{wxWindow}{wxwindow}\\ \helpref{wxEvtHandler}{wxevthandler}\\ \helpref{wxObject}{wxobject} \wxheading{Include files} (only available if \texttt{wxUSE\_DATEPICKCTRL} is set to $1$) \wxheading{Window styles} \twocolwidtha{5cm}% \begin{twocollist}\itemsep=0pt \twocolitem{\windowstyle{wxDP\_SPIN}}{Creates a control without month calendar drop down but with spin control-like arrows to change individual date components. This style is not supported by the generic version.} \twocolitem{\windowstyle{wxDP\_DROPDOWN}}{Creates a control with a month calendar drop down part from which the user can select a date.} \twocolitem{\windowstyle{wxDP\_DEFAULT}}{Creates a control with default style which is the best supported for the current platform (currently wxDP\_SPIN under Windows and wxDP\_DROPDOWN elsewhere).} \twocolitem{\windowstyle{wxDP\_ALLOWNONE}}{With this style, the control allows the user to not enter any valid date at all. Without it -- which is by default -- the control always has some valid date.} \twocolitem{\windowstyle{wxDP\_SHOWCENTURY}}{Forces display of the century in the default date format. Without this flas the century could be displayed or not depending on the default date representation in the system.} \end{twocollist} \wxheading{Event handling} \twocolwidtha{7cm}% \begin{twocollist}\itemsep=0pt \twocolitem{{\bf EVT\_DATE\_CHANGED(id, func)}}{This event fires when the user changes the current selection in the control.} \end{twocollist} \wxheading{See also} \helpref{wxCalendarCtrl}{wxcalendarctrl},\\ \helpref{wxDateEvent}{wxdateevent} \latexignore{\rtfignore{\wxheading{Members}}} \membersection{wxDatePickerCtrl::wxDatePickerCtrl}\label{wxdatepickerctrlctor} \func{}{wxDatePickerCtrl}{\param{wxWindow *}{parent},\rtfsp \param{wxWindowID}{ id},\rtfsp \param{const wxDateTime\& }{dt = wxDefaultDateTime},\rtfsp \param{const wxPoint\& }{pos = wxDefaultPosition},\rtfsp \param{const wxSize\& }{size = wxDefaultSize},\rtfsp \param{long}{ style = wxDP\_DEFAULT | wxDP\_SHOWCENTURY},\rtfsp \param{const wxValidator\& }{validator = wxDefaultValidator}, \param{const wxString\& }{name = ``datectrl"}} Initializes the object and calls \helpref{Create}{wxdatepickerctrlcreate} with all the parameters. \membersection{wxDatePickerCtrl::Create}\label{wxdatepickerctrlcreate} \func{bool}{Create}{\param{wxWindow *}{parent},\rtfsp \param{wxWindowID}{ id},\rtfsp \param{const wxDateTime\& }{dt = wxDefaultDateTime},\rtfsp \param{const wxPoint\& }{pos = wxDefaultPosition},\rtfsp \param{const wxSize\& }{size = wxDefaultSize},\rtfsp \param{long}{ style = wxDP\_DEFAULT | wxDP\_SHOWCENTURY},\rtfsp \param{const wxValidator\& }{validator = wxDefaultValidator}, \param{const wxString\& }{name = ``datectrl"}} \wxheading{Parameters} \docparam{parent}{Parent window, must not be non-\texttt{NULL}.} \docparam{id}{The identifier for the control.} \docparam{dt}{The initial value of the control, if an invalid date (such as the default value) is used, the control is set to today.} \docparam{pos}{Initial position.} \docparam{size}{Initial size. If left at default value, the control chooses its own best size by using the height approximately equal to a text control and width large enough to show the date string fully.} \docparam{style}{The window style, should be left at $0$ as there are no special styles for this control in this version.} \docparam{validator}{Validator which can be used for additional date checks.} \docparam{name}{Control name.} \wxheading{Return value} \true if the control was successfully created or \false if creation failed. \membersection{wxDatePickerCtrl::GetRange}\label{wxdatepickerctrlgetrange} \constfunc{bool}{GetRange}{\param{wxDateTime *}{dt1}, \param{wxDateTime }{*dt2}} If the control had been previously limited to a range of dates using \helpref{SetRange()}{wxdatepickerctrlsetrange}, returns the lower and upper bounds of this range. If no range is set (or only one of the bounds is set), the \arg{dt1} and/or \arg{dt2} are set to be invalid. \wxheading{Parameters} \docparam{dt1}{Pointer to the object which receives the lower range limit or becomes invalid if it is not set. May be \texttt{NULLL} if the caller is not interested in lower limit} \docparam{dt2}{Same as above but for the upper limit} \wxheading{Return value} \false if no range limits are currently set, \true if at least one bound is set. \membersection{wxDatePickerCtrl::GetValue}\label{wxdatepickerctrlgetvalue} \constfunc{wxDateTime}{GetValue}{\void} Returns the currently selected. If there is no selection or the selection is outside of the current range, an invalid object is returned. \membersection{wxDatePickerCtrl::SetRange}\label{wxdatepickerctrlsetrange} \func{void}{SetRange}{\param{const wxDateTime\&}{ dt1}, \param{const wxDateTime\&}{ dt2}} Sets the valid range for the date selection. If \arg{dt1} is valid, it becomes the earliest date (inclusive) accepted by the control. If \arg{dt2} is valid, it becomes the latest possible date. \wxheading{Remarks} If the current value of the control is outside of the newly set range bounds, the behaviour is undefined. \membersection{wxDatePickerCtrl::SetValue}\label{wxdatepickerctrlsetvalue} \func{void}{SetValue}{\param{const wxDateTime\&}{ dt}} Changes the current value of the control. The date should be valid and included in the currently selected range, if any. Calling this method does not result in a date change event.
