Overview of this book

Elegantly-built GUI applications are always a massive hit among users. PySide is an open source software project that provides Python bindings for the Qt cross-platform UI framework. Combining the power of Qt and Python, PySide provides easy access to the Qt framework for Python developers and also acts as an excellent rapid application development platform. This book will take you through everything you need to know to develop UI applications. You will learn about installing and building PySide in various major operating systems as well as the basics of GUI programming. The book will then move on to discuss event management, signals and slots, and the widgets and dialogs available with PySide. Database interaction and manipulation is also covered. By the end of this book, you will be able to program GUI applications efficiently and master how to develop your own applications and how to run them across platforms.

Chapter 4. Events and Signals

In the chapters that we saw so far, we tried out various implementations of readily available functions to build a base GUI by extending the Qt objects without handling custom events. In this chapter, we will look into some of the internal implementations of working concepts of these functions in the context of events and signals. Qt being an event-driven UI toolkit, events and event delivery play an important role in the Qt architecture. We will start this chapter by discussing events and signals, their implementation, and will go on to discuss handling drag and drop events, and drawing functionalities.
