In this article we will see how we can get the previous widget in the focus chain of QCalendarWidget. Focus chain is the list of widgets/children present in the window, they tell the sequence of focus, first item in the focus chain will receive focus first.
In order to do this we will use
previousInFocusChain
method with the QCalendarWidget object.Syntax : calendar.previousInFocusChain()
Argument : It takes no argument
Return : It return QWidget object
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):
# constructor
def __init__( self , parent = None ):
super (Calendar, self ).__init__(parent)
class Window(QMainWindow):
def __init__( self ):
super ().__init__()
# setting title
self .setWindowTitle( "Python " )
# setting geometry
self .setGeometry( 100 , 100 , 500 , 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 cursor
self .calendar.setCursor(Qt.PointingHandCursor)
# setting size of the calendar
self .calendar.resize( 300 , 240 )
# move the calendar
self .calendar.move( 10 , 10 )
# creating a label
label = QLabel( self )
# setting geometry to the label
label.setGeometry( 100 , 280 , 250 , 60 )
# making label multi line
label.setWordWrap( True )
# getting the previous widget in focus change
value = self .calendar.previousInFocusChain()
# setting text to the label
label.setText( "Previous Widget in Focus Chain : " + str (value))
# create pyqt5 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
