Can't get title bar to disappear from widget

What's the point of passing all those flags and setting geometry of the window manually if you are then calling showFullScreen()?

Calling showFullScreen() and update() from a constructor is not a wise thing to do too. Your constructor should only contain the setupUi() call and then somewhere else in your code you should call showFullScreen().

Wow, this is frustrating, I responded to these comments several days ago but they didn't post, apparently. d_stranz--I actually did initialize QMainWindow in the MainWindow constructor, I just forgot to put that in the snippet. (My firewall at work blocks QtCentre ?!?! so I have to reply from home.) Passing window flags from the constructor didn't help. wysota--I had everything together in that snippet just to show that I had tried all those different things, I tried out showFullScreen(), manual settings independently as well.

I'll try to keep update() and showFullScreen() out of the constructor, and see if that helps. Thank you both, so far--
