PyQt5 PushButton not showing

Question

This is the code I am using and the button doesn't show and it only shows a blank window. There is no error in the console.

from PyQt5 import QtWidgets

from PyQt5.QtWidgets import *





import sys



def start():

    app = QApplication(sys.argv)

    w = QWidget()

    w.resize(128,102)

    w.move(0, 0)

    w.setWindowTitle('Simple')

    btn = QtWidgets.QPushButton("Hi")

    btn.move(50, 50)

    btn.resize(btn.sizeHint())

    w.show()



    sys.exit(app.exec_())



start()

This is the window it shows

Answer 1

Try passing the parent argument to the constructor. The parent argument causes the button to be owned by Qt, not PyQt. btn = QtWidgets.QPushButton("Hi", w) should work.
