A Field Guide to App Studio Controls

Here are App Studio's screen controls.

The appearance of these controls will differ based on the device they are running on, based on factors such as screen size, default UI specifications and operating system.

App Studio supports multiple frameworks: jQuery Mobile, Classic and jqWidgets. A framework is a set of controls which share underlying formatting structures. Certain frameworks, such as jQuery Mobile and Classic, are mutually exclusive. Putting them in the same project will lead to conflicts. The IDE will usually prevent you from doing this by accident.

jQuery Mobile Controls

jQuery Mobile provides a set of attractive and powerful controls. Here is an actual App Studio App which uses them:
