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.

Drag and drop technique

There are various ways in which you can transfer data between two objects or applications. Drag and drop is a modern visual technique of transference of data between objects. It enables the user to copy and paste very intuitively. The drag and drop is a combination of two events, namely Dragging and Dropping. The widgets can serve as drag sites, drop sites, or as both. One of the important factors that we should take care of is the MIME type of the object that we would drag or drop. This is to ensure that the information can be transferred safely between applications. The various MIME types that are supported by Qt include plain text, HTML text, URI-list text, image data, and color data. We will explore the Qt classes that are used for this action and shortly test them with an example.

The various classes that are involved in drag and drop and their necessary MIME encoding and decoding are listed in the following table:
