wxDatePickerCtrl
This control allows the user to select a date. Unlike
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 wxUSE_DATEPICKCTRL is set to
.

Window styles
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. |
wxDP_DROPDOWN |
Creates a control with a month
calendar drop down part from which the user can select a date. |
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). |
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. |
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. |
Event handling
EVT_DATE_CHANGED(id, func) |
This event fires when the user
changes the current selection in the control. |

wxDatePickerCtrl::wxDatePickerCtrl
wxDatePickerCtrl(wxWindow * parent,
wxWindowID id,
const wxDateTime& dt = wxDefaultDateTime,
const wxPoint& pos = wxDefaultPosition,
const wxSize& size = wxDefaultSize,
long style = wxDP_DEFAULT | wxDP_SHOWCENTURY,
const wxValidator& validator = wxDefaultValidator,
const wxString& name = ``datectrl")
Initializes the object and calls Create with
all the parameters.
wxDatePickerCtrl::Create
bool Create(wxWindow * parent,
wxWindowID id,
const wxDateTime& dt = wxDefaultDateTime,
const wxPoint& pos = wxDefaultPosition,
const wxSize& size = wxDefaultSize,
long style = wxDP_DEFAULT | wxDP_SHOWCENTURY,
const wxValidator& validator = wxDefaultValidator,
const wxString& name = ``datectrl")
Parameters
- parent
- Parent window, must not be non-NULL.
- id
- The identifier for the control.
- dt
- The initial value of the control, if an invalid date (such as the
default value) is used, the control is set to today.
- pos
- Initial position.
- 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.
- style
- The window style, should be left at
as there are no
special styles for this control in this version.
- validator
- Validator which can be used for additional date checks.
- name
- Control name.
Return value
TRUEif the control was successfully created or FALSEif creation failed.
wxDatePickerCtrl::GetRange
bool GetRange(wxDateTime * dt1, wxDateTime *dt2) const
If the control had been previously limited to a range of dates using
SetRange(), returns the lower and upper
bounds of this range. If no range is set (or only one of the bounds is set),
the dt1 and/or dt2 are set to be invalid.
Parameters
- dt1
- Pointer to the object which receives the lower range limit or
becomes invalid if it is not set. May be NULLL if the caller is not
interested in lower limit
- dt2
- Same as above but for the upper limit
Return value
FALSEif no range limits are currently set, TRUEif at least one bound is
set.
wxDatePickerCtrl::GetValue
wxDateTime GetValue(void) const
Returns the currently selected. If there is no selection or the selection is
outside of the current range, an invalid object is returned.
wxDatePickerCtrl::SetRange
void SetRange(const wxDateTime& dt1, const wxDateTime& dt2)
Sets the valid range for the date selection. If dt1 is valid, it becomes
the earliest date (inclusive) accepted by the control. If dt2 is valid,
it becomes the latest possible date.
Remarks
If the current value of the control is outside of the newly set range bounds,
the behaviour is undefined.
wxDatePickerCtrl::SetValue
void SetValue(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.
