PyQt5 QCalendarWidget – Getting previous widget in focus chain
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 ()) |
