This chapter explained the fundamentals of the Qt Widgets module and how to create a custom UI. Here, you learned to design and build GUIs with Qt Designer. Traditional desktop applications are usually built with Qt Designer. Features such as custom widget plugins allow you to create and use your own widget collection with Qt Designer. We also discussed customizing the look and feel of your application with style sheets and styles, as well as looking at the uses of and differences between widgets, windows, and dialogs. Now, you can create a GUI application with your own custom widgets with extended functionalities and create your own themes for your desktop application.
