pyqt statusbar

PyQt5 supports a window status bar. This is a small bar at the bottom of a window that sometimes appears, it can contain text messages. To add a status bar add the line:

self.statusBar().showMessage('Message in statusbar.')

A statusbar can be added to the main window (QMainWindow). It is one of the methods the class itself contains;

PyQt5 statusbar example:
The program below adds a statusbar to a PyQt5 window:

import sys
from PyQt5.QtWidgets import QApplication, QWidget, QMainWindow
from PyQt5.QtGui import QIcon

class App(QMainWindow):

    def __init__(self):
        super().__init__()
        self.title = 'PyQt5 status bar example - pythonspot.com'
        self.left = 10
        self.top = 10
        self.width = 640
        self.height = 480
        self.initUI()

    def initUI(self):
        self.setWindowTitle(self.title)
        self.setGeometry(self.left, self.top, self.width, self.height)
        self.statusBar().showMessage('Message in statusbar.')
        self.show()

if __name__ == '__main__':
    app = QApplication(sys.argv)
    ex = App()
    sys.exit(app.exec_())

The example creates a window (QMainWindow). We set the screen parameters using:

self.left = 10
self.top = 10
self.width = 640
self.height = 480

Window properties are set in the initUI() method which is called in the constructor. The method:

statusBar().showMessage()

sets the text on the statusbar.
