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
# 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 ())
