An example rich UI application is developed for a Beagle board that uses the TMP36 temperature sensor. The Qt framework is the focus of the discussion, largely due to its comprehensive libraries of code. Different software application frameworks are examined for rich UI development, such as GTK+ and Qt. Also introduced are different Beagle board architectures that can support rich UIs, such as general-purpose computing, touch screen display modules, and virtual network computing (VNC). Rich UIs allow for a depth of interaction with an application that is not possible with command-line interfaces (CLIs)-in particular, the addition of graphical display elements can result in easier-to-use applications. In this chapter you are introduced to rich user interface (UI) architectures and application development on the Beagle Board platform. The summary introduction to the chapter is as follows: This is the chapter web page to support the content in Chapter 13 of the book: Exploring BeagleBone – Tools and Techniques for Building with Embedded Linux.
