Thank you! That might be what I want. I'll check it out on Monday.

The members that I need to reference all have the same names in the two .ui files. Seems like there should be a C++ template way to do this, but I'm not as clever with that kind of stuff as I might be.

Create an empty QMainWindow (in code), then at runtime in the constructor of said window load the proper UI file using the QUILoader (what it loads is your ui-> pointer), and use the setCentralWidget() method of the window to set the widgets from the UI file into the window. I think that’s how it goes :-)
