        return "The calendar control allows the user to pick a date interactively. For this, it displays a window containing several parts: the control to pick the month and the year at the top (either or both of them may be disabled) and a month area below them which shows all the days in the month. The user can move the current selection using the keyboard and select the date (generating EVT_CALENDAR event) by pressing <Return> or double clicking it."
