Chapter 7: Application Bar

C H A P T E R  7

Application Bar

When you're ready to program your Windows Phone application in Visual Studio 2010, you'll know what general features your application will provide. Each of the major application features will need to be accessible via a shortcut or some form of a navigation menu. For Windows Phone applications, Microsoft recommends that you use a standard Windows Phone Application Bar to provide shortcuts for most common tasks withinthe application. Metro UI design concepts for Windows Phones were covered in Part 1 of this book. The use of an Application Bar within the applicationhelps ensure that these guidelines are properly observed.

An Application Bar is essentially a Windows Phone menu system with clickable icons that conform to the general Metro UI guidelines provided by Microsoft. For example, take a look at the Windows Phone version of the popular social networking application Foursquare (one place you can find its screenshots is http://4square.codeplex.com). At the bottom of the screen, you will see an Application Bar with shortcuts to most common features of the application. Another example is Graphic.ly (www.pcworld.com/article/191549/graphicly.html), an application that uses Deep Zoom capabilities of Silverlight to provide an immersive comic book–reading experience. On its Application Bar, Graphic.ly naturally has shortcuts to zoom into and out of the comic book contents, since those features are the most important ones for that application. The screenshots of those applications appear side by side in Figure 7-1. Note that you can also download the full source code for the Foursquare application—something that may prove to be a handy learning tool—from the preceding link.
