In this article we will see how we can implement the leave event for the QCalendarWidget. A leave event is sent to the calendar when the mouse cursor leaves the calendar. This event handler can be reimplemented in a subclass to receive calendar leave 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 leave event
def leaveEvent(self, event):
# setting to the text to the label
window.label.setText("Leave Event Take place")
Implementation steps:
1. Create a Calendar class that inherits the QCalendarWidget
2. Inside the Calendar class override the leaveEvent 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
Python3
# importing libraries from PyQt5.QtWidgets import *from PyQt5 import QtCore, QtGui from PyQt5.QtGui import *from PyQt5.QtCore import *import sys # QCalendarWidget Class class Calendar(QCalendarWidget): def __init__(self, parent = None): super(Calendar, self).__init__(parent) # overriding the leave event def leaveEvent(self, event): # setting to the text to the label window.label.setText("Leave Event Take place") class Window(QMainWindow): def __init__(self): super().__init__() # setting title self.setWindowTitle("Python ") # setting geometry self.setGeometry(100, 100, 650, 400) # calling method self.UiComponents() # showing all the widgets self.show() # method for components def UiComponents(self): # creating a QCalendarWidget object # as Calendar class inherits QCalendarWidget self.calendar = Calendar(self) # setting geometry to the calendar self.calendar.setGeometry(50, 10, 400, 250) # setting cursor self.calendar.setCursor(Qt.PointingHandCursor) # creating label to show the properties self.label = QLabel(self) # setting geometry to the label self.label.setGeometry(100, 280, 250, 60) # making label multi line self.label.setWordWrap(True) # setting text to the label self.label.setText("No Event") # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) |
Output :
