Problem creating two windows with parent-child relationship when using pyqt5 [Copy link]

First, I created two QWidget objects, then set the parent-child relationship and the corresponding background color. I observed that the background color of the parent object surrounded the child object. However, I wrote a class that completely inherited from QWidget, which did not work. I could only see the background color of the parent object. from PyQt5.Qt import *

class Window(QWidget):
def __init__(self):
super().__init__()

if __name__ == '__main__':
import sys
qApp = QApplication(sys.argv)
window = Window()
window.setStyleSheet("background-color:yellow")
window.resize(500,500)
window.setWindowTitle("jiuzhe ")

window1 = Window()
window1.setStyleSheet("background-color:red")
window1.resize(300,300)
window1.move(0,0)
window1.setParent(window)

print(window)
print(window1.parent())

window.show()
window1.show()
sys.exit(qApp.exec())

Class inheritance

Because it inherits from QWidget, it of course inherits the parent object, so you can see the background color of the parent object.

Correct answer. It seems that you have a very good foundation in pyqt. Thanks for the answer.
