PyQt5 QCalendarWidget – Setting Properties

PyQt5 is a Python module that provides bindings for the Qt libraries. Qt is a cross-platform application development framework widely used for the development of graphical user interface (GUI) programs. PyQt5 provides an extensive set of Python bindings for the Qt toolkit, including the QCalendarWidget class, which provides a calendar widget for selecting dates.

Setting Properties of QCalendarWidget

You can customize the appearance and behavior of QCalendarWidget by setting various properties of the object. Here, we will discuss some of the commonly used properties of the QCalendarWidget class.

1. selectingDate()

The selectedDate() method of the QCalendarWidget class retrieves the currently selected date in the widget.

date = calendar.selectedDate()

2. setMinimumDate() and setMaximumDate()

The setMinimumDate() and setMaximumDate() methods of the QCalendarWidget class set the minimum and maximum dates that can be selected in the widget, respectively.

calendar.setMinimumDate(QDate(2021, 1, 1))
calendar.setMaximumDate(QDate(2022, 12, 31))

3. setDateRange()

The setDateRange() method of the QCalendarWidget class sets both the minimum and maximum dates that can be selected in the widget.

calendar.setDateRange(QDate(2021, 1, 1), QDate(2022, 12, 31))

4. setSelectionMode()

The setSelectionMode() method of the QCalendarWidget class sets the selection mode for the widget. By default, the selection mode is set to SingleSelection, which allows the user to select only one date at a time. Other values for selection mode include NoSelection, MultiSelection, and ExtendedSelection.

calendar.setSelectionMode(QCalendarWidget.ExtendedSelection)

5. setHorizontalHeaderFormat() and setVerticalHeaderFormat()

The setHorizontalHeaderFormat() and setVerticalHeaderFormat() methods of the QCalendarWidget class set the format of the horizontal and vertical headers of the widget, respectively. By default, the horizontal header shows weekday names, and the vertical header shows week numbers. You can customize these formats as below.

calendar.setHorizontalHeaderFormat(QCalendarWidget.LongDayNames)
calendar.setVerticalHeaderFormat(QCalendarWidget.ISOWeekNumbers)

6. setGridVisible()

The setGridVisible() method of the QCalendarWidget class sets the visibility of the grid lines between calendar cells to either True or False.

calendar.setGridVisible(False)
