PyQt5 QCalendarWidget – Activated signal
  • Last Updated : 03 Jun, 2020

In this article we will see how we can get the activated signal from the QCalendarWidget. Activated signal is emitted whenever the user presses the Return or Enter key or double-clicks a date in the calendar widget.

In order to do this we will use actiavted method with the QCalendarWidget object.

Syntax : calender.activated.connect(lambda: print(“Calender Got activated”))

Argument : It takes method as argument

Action Performed : It will print the message whenever activated signal get emitted
