The first step in creating desktop applications with PyQt is getting a window to show up on your desktop, in this article, we will see how we can change the color of this window. In order to change the color of the main window we use setStylesheet() method.
Syntax : setStyleSheet(“background-color: grey;”)
Argument : It takes string as an argument.
Example #1:
# importing the required libraries from PyQt5.QtWidgets import * from PyQt5 import QtCorefrom PyQt5.QtGui import * import sys class Window(QMainWindow): def __init__(self): super().__init__() # changing the background color to yellow self.setStyleSheet("background-color: yellow;") # set the title self.setWindowTitle("Color") # setting the geometry of window self.setGeometry(0, 0, 400, 300) # creating a label widget self.label = QLabel("Yellow", self) # moving position self.label.move(100, 100) # setting up border self.label.setStyleSheet("border: 1px solid black;") # show all the widgets self.show() # create pyqt5 appApp = QApplication(sys.argv) # create the instance of our Windowwindow = Window() # start the appsys.exit(App.exec()) |
Output :
Example #2:
# importing the required libraries from PyQt5.QtWidgets import * from PyQt5 import QtCorefrom PyQt5.QtGui import * import sys class Window(QMainWindow): def __init__(self): super().__init__() # changing the background color to cyan self.setStyleSheet("background-color: cyan;") # set the title self.setWindowTitle("Color") # setting the geometry of window self.setGeometry(0, 0, 400, 300) # creating a label widget self.label = QLabel("Cyan", self) # moving position self.label.move(100, 100) # setting up border self.label.setStyleSheet("border: 1px solid black;") # show all the widgets self.show() # create pyqt5 appApp = QApplication(sys.argv) # create the instance of our Windowwindow = Window() # start the appsys.exit(App.exec()) |
Output :
