PyQt5 QCalendarWidget – Current Page Changed signal
In this article we will see how we can get the current page change signal from the QCalendarWidget. Current page changed signal is emitted when the currently shown month is changed.
In order to do this we will use currentPageChanged method with the QCalendarWidget object.
Syntax : calendar.currentPageChanged.connect(lambda: print(“Page Changed”))
Argument : It takes method as argument
Action Performed : It will print the message whenever activated signal get emitted
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 class Window(QMainWindow): def __init__( self ): super ().__init__() # setting title self .setWindowTitle( "Python " ) # setting geometry self .setGeometry( 100 , 100 , 600 , 400 ) # calling method self .UiComponents() # showing all the widgets self .show() # method for components def UiComponents( self ): # creating a QCalendarWidget object calendar = QCalendarWidget( self ) # setting geometry to the calendar calendar.setGeometry( 10 , 10 , 400 , 250 ) # creating a label label = QLabel( self ) # setting geometry to the label label.setGeometry( 100 , 280 , 250 , 60 ) # making label multi line label.setWordWrap( True ) # text text = "Current Page hanged signal (No.) : " # current count self .count = 0 # getting the current page change signal and # when receives the signal printing the message calendar.currentPageChanged.connect( lambda : label.setText(text + str (get_count()))) # method to increase the count value def get_count(): self .count + = 1 return self .count # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App. exec ()) |
