How to display an overlapping window using PyQt4

I want to display a window when I press a button. When I click the button the parent window remains there and new window is displayed for a fraction of a second and disappears. How can I display the new window over the previous window that contains the button.

It sounds like you're not keeping a reference to the child window, and so it's getting garbage-collected immediately after it's shown.

Your button handler probably looks something like this:

def handleOpenWindow(self):
    window = QMainWindow()
    window.show()

Instead, you need to do this:

    self.window = QtGui.QMainWindow()
    self.window.show()

Or this:

    window = QtGui.QMainWindow(self)
    window.show()
