I try to set a custom style on a widget, a QScrollArea specifically, and nothing happens, so I go up the hierarchy and set the custom style to a QDialog, which is the main widget in the application. Still nothing. So I go up and set it to the application object in main(). It works!

The only problem is eventually this QDialog is going to be a .dll so it won't have an application object. How do I make this work?
