\section{\class{wxDatePickerCtrl}}\label{wxdatepickerctrl}
|
|
|
|
This control allows the user to select a date. 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, except PalmOS where date is selected using native dialog.
|
|
|
|
It is only available if \texttt{wxUSE\_DATEPICKCTRL} is set to $1$.

|
\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),
|
|
\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{NULL} 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::SetFormat}\label{wxdatepickerctrlsetformat}
|
|
|
|
\func{void}{SetFormat}{\param{const wxChar*}{ format}}
|
|
|
|
Please note that this function is only available in the generic version of this
|
|
control. The native version always uses the current system locale.
|
|
|
|
Sets the display format for the date in the control. See wxDateTime for the
|
|
meaning of format strings.
|
|
|
|
\wxheading{Remarks}
|
|
|
|
If the format parameter is invalid,
|
|
the behaviour is undefined.
|
|
|
|
|
|
\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.
