Aspects of the subject matter described herein relate to generating and propagating commands. In aspects, elements of a graphical user interface may include an input binding which associates a gesture with a command. When a gesture is received, the command is generated depending on which element has focus. In addition, elements of the graphic user interface may also define methods to call when commands are received. When an event or a command is received, a hierarchical data structure of elements representable on the graphical user interface may be traversed to respond to the event or command.

An inheritance context is created for a graphics primitive object that is a property of a visual element. The inheritance context can be used to make some element information (e.g., information in resource dictionaries, name dictionaries, and inheritable properties that reside in the element tree containing the visual element) available to the graphics primitive object.

The techniques and mechanisms described herein are directed at property management mechanisms that operate within an on-demand property system. The property management mechanisms support the caching of property values on an as needed basis, allow a plurality of object instances to utilize the same property via attached properties, overriding default information associated with a property on a per type basis, obtaining values for a property from an external source, and the like. In addition, the on-demand property system provides validation and control for each property instance. The property management mechanisms minimize the storage requirements and provide flexibility without requiring additional code from the developers.

Described is a method and system in which storyboard objects coordinate the animation of multiple elements and/or media displayed on a computer graphics display. Storyboards relate properties of elements in an element tree to a timeline, such that the properties associated with a storyboard are animated/play together as a group by starting, stopping, seeking or pausing the storyboard. Triggers, such as controlled by user interaction with the displayed information, including property triggers that change values in response to a state change, and event triggers that fire events, may cause the storyboard to start, stop, pause and seek. Storyboards may be used in XAML-based programs, and may be directly associated with elements, or indirectly associated with elements via styles. Complex properties and changeables are supported. Media playback may be controlled via storyboards, and thereby coordinated with other media playback and/or animations.

An improved system and method for styling content in a graphical user interface control is provided. An application may define a user interface control having a data object of any type of singular content, including another user interface control. An application may include style declarations that may associate a style resource with the user interface control and a style resource may be dynamically selected for presenting the data object of the user interface control. The style resources may define property values that may be selectively applied to specify a visual representation for the user interface control and data object, such as a visual subtree. A visual representation of the user interface control with the data object may be generated and then a display representation may be rendered for presentation on a user interface display.

Priority binding enables a one-to-many mapping of a target to a source without requiring complex code development by the specification of one or more binding statements. During runtime, these bindings are evaluated. The highest priority binding that evaluates successfully is executed, controlling the two-way transfer of information between source and target. During execution, all possible data binding pathways are monitored. If a binding that has a higher priority than the existing binding evaluates successfully, the existing binding is terminated and the new binding is executed.

An improved system and method for displaying a user interface object using an associated style is provided. To this end, an application may include style declarations that may associate a style resource with a user interface object. The style resource may define property values that may be selectively applied to a user interface object, may specify a visual representation for the user interface object, such as a visual subtree, and may specify additional property values to be conditionally applied to a user interface object. A styling engine may be provided for applying a style resource to a user interface object. A visual representation of the user interface objects with the applied property values may be generated and then a display representation may be rendered for presentation on a user interface display.

In one embodiment, a social networking system the social networking system filters content objects based upon the compatibility between the application and the detected device platform. In particular embodiments, content objects are only displayed on a particular platform if there exists an optimized version of the application generating the content object for the particular platform.
摘要:
In an implementation of data association, a data item has a data item property with an associated value and a user interface element has an element property with a value that can be defined by an association to the data item property. A binding definition associates the element property of the user interface element with the data item property such that an application program which generates a user interface for display can be developed independent of the data item, and such that the data item can be developed independent of display-related information corresponding to the user interface element.
