Hide a window in the constructor immediately after it is created

Question

I want to hide a window immediately after it is created. It works only if I do this with the help of button or something.

class Example(QWidget):
    def __init__(self, parent=None):
        super(Example, self).__init__(parent)
        self.hide() # doesn't work
        self.btn = QPushButton('Hide', self)
        self.btn.clicked.connect(self.click) # works
        self.btn.show()

    def click(self): # works
        self.hide()

Apparently it seems that the code should work. What may be happening is that you are calling show() after creating the object. For example:

example = Example()
example.show()
