It sounds like you may be looking for the QUiLoader Class (https://doc.qt.io/qt-5/quiloader.html <https://doc.qt.io/qt-5/quiloader.html>)? 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 :-) --- Israel Brewster Software Engineer Alaska Volcano Observatory Geophysical Institute - UAF 2156 Koyukuk Drive Fairbanks AK 99775-7320 Work: 907-474-5172 cell: 907-328-9145 > _______________________________________________ > Interest mailing list > Interest@qt-project.org > https://lists.qt-project.org/listinfo/interest
