Chapter 3: GUI Design Using Qt Widgets

Qt Widgets is a module that offers a set of user interface (UI) elements for building classic UIs. In this chapter, you will be introduced to the Qt Widgets module and will learn about basic widgets. We will look at what widgets are and the various kinds that are available for creating graphical UIs (GUIs). In addition to this, you will be introduced to layouts with Qt Designer, and you will also learn how to create your own custom controls. We will take a close look into what Qt can offer us when it comes to designing sleek-looking GUIs with ease. At the beginning of this chapter, you will be introduced to the types of widgets provided by Qt and their functionalities. After that, we will walk through a series of steps and design our first form application using Qt. You will then learn about Style Sheets, Qt Style Sheets (QSS files), and theming.

The following main topics will be covered in this chapter:

  • Introducing Qt widgets
  • ...
