/**
|
|
@class 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.
|
|
|
|
It is only available if @c wxUSE_DATEPICKCTRL is set to 1.
|
|
|
|
@beginStyleTable
|
|
@style{wxDP_SPIN}
|
|
Creates a control without a month calendar drop down but with
|
|
spin-control-like arrows to change individual date components. This
|
|
style is not supported by the generic version.
|
|
@style{wxDP_DROPDOWN}
|
|
Creates a control with a month calendar drop-down part from which
|
|
the user can select a date. This style is not supported in OSX/Cocoa
|
|
native version.
|
|
@style{wxDP_DEFAULT}
|
|
Creates a control with the style that is best supported for the
|
|
current platform (currently wxDP_SPIN under Windows and OSX/Cocoa
|
|
and wxDP_DROPDOWN elsewhere).
|
|
@style{wxDP_ALLOWNONE}
|
|
With this style, the control allows the user to not enter any valid
|
|
date at all. Without it - the default - the control always has some
|
|
valid date. This style is not supported in OSX/Cocoa native version.
|
|
@style{wxDP_SHOWCENTURY}
|
|
Forces display of the century in the default date format. Without
|
|
this style the century could be displayed, or not, depending on the
|
|
default date representation in the system. This style is not
|
|
supported in OSX/Cocoa native version currently.
|
|
@endStyleTable
|
|
|
|
As can be seen from the remarks above, most of the control style are only
|
|
supported in the native MSW implementation. In portable code it's
|
|
recommended to use @c wxDP_DEFAULT style only, possibly combined with @c
|
|
wxDP_SHOWCENTURY (this is also the style used by default if none is
|
|
specified).
|
|
|
|
@beginEventEmissionTable{wxDateEvent}
|
|
@event{EVT_DATE_CHANGED(id, func)}
|
|
Process a wxEVT_DATE_CHANGED event, which fires when the user
|
|
changes the current selection in the control.
