In this article we will see how we can check if the signals that are associated with the QCalendarWidget are in blocked state or not. There are various signals associated with the calendar such as date change signals page change signal etc. Actions are added to the calendar suing this signals only. We can block signals with the help of blockSignals method.
In order to do this we will use
signalsBlockedmethod with the QCalendarWidget object.Syntax : calendar.signalsBlocked()
Argument : It takes no argument
Return : It return bool
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 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 self.calender = QCalendarWidget(self) # setting geometry to the calender self.calender.setGeometry(50, 10, 400, 250) # creating a label label = QLabel(self) # setting geometry label.setGeometry(120, 280, 200, 60) # making it multi line label.setWordWrap(True) # adding action to the calendar self.calender.selectionChanged.connect(lambda: label.setText("Selection Changed Signal")) # adding action to the calendar self.calender.currentPageChanged.connect(lambda: label.setText("Page Changed Signal")) # blocking the signals self.calender.blockSignals(True) # getting signals blocked state value = self.calender.signalsBlocked() # setting text to the label label.setText("Signals Blocked : " + str(value)) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # start the app sys.exit(App.exec()) |
