This package for Windows Phone 7 Series contains a set of 64 app bar icons that you can use when developing applications for Windows Phone. In addition to the 64 icons in PNG format (32 dark and 32 light), this package also contains vector versions that can be easily imported into Microsoft Expression Blend 4 Beta when using the Microsoft Expression Blend Add-in Preview for Windows Phone.
The Application Bar is a system control that allows you to quickly and easily add a toolbar to your Windows Phone 7 Series application. The Application Bar is displayed as a row of between one and four icon buttons along the bottom of the phone’s screen. The icon buttons are used to provide users with quick access to an application’s most common tasks. The opacity of the Application Bar can be set to between 0 and 1. When the opacity is less than 1, the icon buttons are overlaid over the current page content. When the opacity is 1, the icon buttons appear in a rectangle with a background color matching the phone’s current theme, and the page content is resized to fill the space not covered by the application bar.
In addition to the row of icon buttons, applications can provide additional actions to the Application Bar by adding one or more text-based menu items. These items are displayed in a list that slides up from underneath the icon buttons when the user clicks the ellipsis to the right of the icon buttons or the empty space to the left of the icon buttons. The Application Bar menu is not hierarchical, in that the menu item list is not considered to be a submenu of any of the icon buttons. Instead, the menu items are used for application actions that are less frequently used and for actions that are difficult to convey with an icon and therefore require a textual representation.
The Application Bar is simple for developers to include in their applications. The icon buttons and menu items can be initialized and added to the bar in a page’s XAML file or using C#. The icon button and menu item expose the Click Event that can be handled like most Silverlight and Windows Forms controls.
