In this article we will see how to create a digital clock using PyQt5, this digital clock will basically tells the current time in the 24 hour format.
In order to create a digital clock we have to do the following:
1. Create a vertical layout
2. Create label to show the current time and put it in the layout and align it to the center.
3. Create a QTimer object
4. Add action to the QTimer object such that after every 1sec action method get called.
5. Inside the action method get the current time and show that time with the help of label.
Below is the implementation –
# importing required librarie import sys from PyQt5.QtWidgets import QApplication, QWidget from PyQt5.QtWidgets import QVBoxLayout, QLabel from PyQt5.QtGui import QFont from PyQt5.QtCore import QTimer, QTime, Qt class Window(QWidget): def __init__(self): super().__init__() # setting geometry of main window self.setGeometry(100, 100, 800, 400) # creating a vertical layout layout = QVBoxLayout() # creating font object font = QFont('Arial', 120, QFont.Bold) # creating a label object self.label = QLabel() # setting centre alignment to the label self.label.setAlignment(Qt.AlignCenter) # setting font to the label self.label.setFont(font) # adding label to the layout layout.addWidget(self.label) # setting the layout to main window self.setLayout(layout) # creating a timer object timer = QTimer(self) # adding action to timer timer.timeout.connect(self.showTime) # update the timer every second timer.start(1000) # method called by timer def showTime(self): # getting current time current_time = QTime.currentTime() # converting QTime object to string label_time = current_time.toString('hh:mm:ss') # showing it to the label self.label.setText(label_time) # create pyqt5 app App = QApplication(sys.argv) # create the instance of our Window window = Window() # showing all the widgets window.show() # start the app App.exit(App.exec_()) |
