In this article we will see how we can implement the enter event for the QCalendarWidget. A enter event is sent to the calendar when the mouse cursor enters the calendar. This event handler can be reimplemented in a subclass to receive calendar enter events which are passed in the event parameter.
Below is the Calendar class code
# QCalendarWidget Class
class Calendar(QCalendarWidget):
# constructor
def __init__(self, parent=None):
super(Calendar, self).__init__(parent)
# overriding the enter event
def enterEvent(self, event):
# setting to the text to the label
window.label.setText("Enter Event Take place")
Implementation steps:
1. Create a Calendar class that inherits the QCalendarWidget
2. Inside the Calendar class override the enterEvent and inside the event set the text to the label
3. Create a main window class
4. Create a Calendar object inside the main window
5. Set various properties to the calendar
Below is the implementation
