How can I get more than the user interface for QMainWindow?

Question

I would like to have a QMainWindow that can change it at runtime, i.e. when the user clicks a button. Besides saving links to different user interface classes created by QtDesigner, is there any other way to do this? Maybe by storing each user interface in a layout? What do you think?

Answer 1

I think I got it now.

You have a QMainWindow, and when a certain event is fired, you want to change the appearance of that particular window, for example, remove some buttons, add a tree structure widget or not.

Answer 6

You can use QTabWidgetand hide your buttons. Then you can design each graphical interface in a separate window tabWidget. This has the advantage over hiding frames that you won't clutter up with your Qt Creator window.
