Abstract

Methods and apparatus, including computer program products, for developing user interface applications using configurable patterns and for executing such pattern-based applications. The applications can be developed by generating a graphic representation of a pattern, which can include multiple pattern elements having prearranged user interface elements. The pattern can specify predefined actions that can be performed using the user interface elements, and the graphic representation can include graphic objects corresponding to the pattern elements. Application development can further include receiving user input identifying a selected graphic object and modifying the graphic representation to display information regarding the pattern element corresponding to the selected graphic object.
