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 QtCore
from 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 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
|
Output :
Example #2:
# importing the required libraries from PyQt5.QtWidgets import * from PyQt5 import QtCore
from 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 app App = QApplication(sys.argv)
# create the instance of our Window window = Window()
# start the app sys.exit(App. exec ())
