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.

Layout management

A layout can be defined as the sizing, spacing, and placement of content within a GUI window. It defines the visual structure of a user interface. Effective layout management will please users by assisting them in quickly locating what the users want most from the application, and also helps in making out the differences between a good informative design and confusing, puzzling designs for the application. Therefore, management of layout in a window-style application is a crucial success factor for any GUI application. A good layout must have a priority focus, smooth flow, logical grouping, relative emphasis, and coordinated alignment.

In PySide, we use two approaches to layout management. They are as follows:

  • Absolute positioning: This is a crude way of setting the layout manually for each widget by giving them their position and size

  • Layout containers: This is a way to handle the automatic positioning and resizing of widgets by the layout management classes used in Qt
