pyqt: show() for labels shows up in different window?

Question

Here is part of my code that is in my function which is called when a user presses a button on the GUI.

self.titlelbl.clear()  #clear labels
self.genrelbl.clear()
self.ratinglbl.clear()
#........ Other code ....

self.titlelbl = QLabel(self.movie['title'])  #Labels, defined earlier 
self.genrelbl = QLabel(self.movie['genre'])
self.ratinglbl = QLabel(self.movie['rating'])

self.titlelbl.show()     #Show labels
self.genrelbl.show()
self.ratinglbl.show()

The issue I'm having is that when the new labels show up again the information on the labels is correct but the GUI opens up a new window for each label instead of just displaying them in the main GUI window, like it displays when you first open the program. What is causing this?

Thank you.

You need to specify parent for each label.

...
self.titleLbl = QLabel(self, self.movie['title'])
...

then add the labels to the layout of the mainWindow.
