A QtGui.QCalendarWidget provides a monthly based calendar widget. It allows a user to select a date in a simple and intuitive way.

The example has a calendar widget and a label widget. The currently selected date is displayed in the label widget.

cal = QtGui.QCalendarWidget(self)

We construct a calendar widget.

cal.clicked[QtCore.QDate].connect(self.showDate)

If we select a date from the widget, a clicked[QtCore.QDate] signal is emitted. We connect this signal to the user defined showDate() method.

def showDate(self, date):         self.lbl.setText(date.toString())

We retrieve the selected date by calling the selectedDate() method. Then we transform the date object into string and set it to the label widget.
