You can't if you're in the constructor.
What you have to do, is have your constructor post an event to show or exit. I use a singleshot timer with a time of 0. This will post the event immediately after the constructor is done.

Subject: [PyQt] properly exiting application while still in init
In the __init__ method of a standard QDialog I check for some requirements to be fulfilled before the gui is shown (I communicate with a server over a QTcpSocket for that matter) If the conditions fail I want to exit the Application. How would I properly do that?
Currently I tried:
socket.close() #first close the socket
self.close() #close the window, does not do anything in the init because the window is not actually shown yet
sys.exit() works but gives me an error (QWaitCondition: Destroyed while threads are still waiting)
What could I try next?
