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.

This can be adjusted with the QToolBar.setAllowedAreas() function. The tool bar can be set as movable or immovable by setting it with the QToolBar.setMovable() function. The style and size of the icons can be defined by the underlying platform, which can also be controlled. When it is resized in a way that is too small to hold all the icons, an Extension button will appear, which on clicking expands to all items.

Toolbar buttons are added using actions as seen in the menu bar creation in the previous section; we can even use the same actions. The following example demonstrates the creation of a toolbar and its usage:

def CreateToolBar(self):
