Overview of this book

Qt 5, the latest version of Qt, enables you to develop applications with complex user interfaces for multiple targets. It provides you with faster and smarter ways to create modern UIs and applications for multiple platforms. This book will teach you to design and build graphical user interfaces that are functional, appealing, and user-friendly. In the initial part of the book, you will learn what Qt 5 is and what you can do with it. You will explore the Qt Designer, discover the different types of widgets generally used in Qt 5, and then connect your application to the database to perform dynamic operations. Next, you will be introduced to Qt 5 chart which allows you to easily render different types of graphs and charts and incorporate List View Widgets in your application. You will also work with various Qt modules, like QtLocation, QtWebEngine, and the networking module through the course of the book. Finally, we will focus on cross-platform development with QT 5 that enables you to code once and run it everywhere, including mobile platforms. By the end of this book, you will have successfully learned about high-end GUI applications and will be capable of building many more powerful, cross-platform applications.

The video player

In the previous section, we have learned how to create an audio player. In this chapter, we will further improvise our program and create a video player using Qt and C++.

Designing a user interface for video players

The next example is that of the video player. Since QMediaPlayer also supports video output, we can use the same user interface and C++ code from the previous audio player example, and just make some minor changes to it.

  1. First, open project file (.pro) and add in another keyword, called multimediawidgets:
QT += core gui multimedia multimediawidgets 
  1. Then, open up mainwindow.ui and add a Horizontal Layout (name it as movieLayout) above the timeline slider. After that, right-click on the layout...
