Hey guys,
first of all english is not my first language so im sorry for my rough english.

I want to creat a mainwindow and i got some problems to design it.
1. How i build an application with only one window and a menu? I call "setCentralWidget" and swap with this between my widgets if the user click on a button in the menu?
2.I want to have small menu like in the qt creater(Welcome, Edit, design...). How i realise it. There are already a class for this? Maybe i have to use the QDockWidget and modify it?


greets
