C designer file not updating

This is useful when customizing programs to suit various user needs, such as extra large icons or a different colour scheme for accessibility support.

For more information, see widgets-and-dialogs-with-auto-connect. The advantages of this approach are its simple use of inheritance to provide a QWidget-based interface, and its encapsulation of the user interface widget variables within the data member.

We can use this method to define a number of user interfaces within the same widget, each of which is contained within its own namespace, and overlay (or compose) them.

You create user interface components with Qt Designer and use Qt's integrated build tools, qmake and uic, to generate code for them when the application is built.

This approach is used in the Multiple Inheritance example.
