Customizing basic style sheets

In the previous recipe, you learned how to apply a style sheet to a widget with Qt Designer. Let's go crazy and push things further by creating a few other types of widgets and change their style properties to something bizarre for the sake of learning.

This time, however, we will not apply the style to every single widget one by one, but we will learn to apply the style sheet to the main window and let it inherit down the hierarchy to all the other widgets, so that the style sheet is easier to manage and maintain in the long run.
