Abstract: An operating system's desktop window manager uses a presentation framework that enables many different visual effects and standardized mechanisms for graphic presentation, including data binding. The presentation framework may be available through a markup language for the desktop window manager as well as applications on the computer desktop. The presentation framework may enable animations, themes, styles, 3D functionality, or other complex graphical features to be applied to the application windows by the desktop window manager as well as for the client areas controlled by the applications. By using a presentation framework with functionality adapted for general computer applications, many advanced functions may be applied to desktop windows without low level programming.

Abstract: Aspects of the subject matter described herein relate to directing focus to elements of a graphical user interface in response to focus events. In aspects, a program may include multiple focus scopes each of which may include elements capable of receiving keyboard input. When an element receives keyboard focus, information regarding the element is updated to indicate that the element has or had keyboard focus. Thereafter, focus scope may be changed to a focus scope other than the one including the element. When changing the focus scope back to the focus scope that includes the element, the information may be used to give the element keyboard focus.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: In an implementation of data binding, a bind object implements an apply-value interface, and a user interface element has a user interface property with an associated value which is designated as the bind object in a markup language. A platform processes the markup language and calls the apply-value interface of the bind object with arguments that include the user interface element and the user interface property to generate an expression such that the associated value of the user interface property can be determined.

Abstract: The application programming interfaces 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.

Abstract: A method and system for mapping a tag in a markup language (ML) document to a class using namespaces is described. A parser in a computing system analyzes the tag in the ML document. A definition file location attribute related to the tag is referenced in the ML document. A definition file associated with definition file location attribute is retrieved. A namespace related to the tag is referenced within the definition file to determine the class associated with the tag. The class is located in an assembly such that the tag is mapped to the class.

Abstract: Described is a system and method for declaring a resource element in markup that is intended to be instantiated lazily only upon use at run-time rather than always at markup load time. In one embodiment, the invention provides a parent resources tag that encloses resource elements that may be any type of markup element. On compile, a specially prepared compiler/parser identifies the Resource tag and creates definitional information sufficient to describe the resource elements in such a manner that the resource elements are defined but not created at run-time when the markup is first loaded, and are created only upon use at run-time. A resource may be defined to be shared or non-shared. If shared, the resource is instantiated only once and that same instance is handed out each time the resource is accessed. If non-shared, a new instance of the resource is always created and handed out on each access of the resource.

Abstract: The present invention is directed to a method and system for compiling a markup language file into an executable application or library dll. The system may also compile a code-behind file associated with the markup language file. The compiling system may include a parser for parsing the markup language file and providing the compiling system with detailed token information to the compiling system. This token information could be user code snippets or non-code token information such as tags, properties or events in the markup. The compiling system may also include a binary file generator for generating a binary file from the non-code token information, wherein the binary file contains one record for each non-code token. Additionally, the system may include a code generator for generating a language-independent tree of code expressions based on the token information, wherein the code expressions represent the markup language file as a class.

Abstract: The visual appearance of a user interface element can be specified in a visual style document divorced from its semantic implementation. The visual style document can be used to specify a visual style including a set of sub-elements used for composing composite user interface element. Selected properties of the sub-elements may be exposed as properties of the composite element itself such that values specified for properties of the composite user interface element can be consumed by corresponding properties of the sub-elements. The style document can also be used to specify values for selected visual properties described in a named resource that may be independent of the style document. Changes in functional aspects of selected sub-elements of composite user interface elements can be used to drive changes in properties of the composite user interface element or other sub-elements by triggering commands that the other elements may be responsive to.

Abstract: Methods and systems are provided for preparing for presentation a graphical element in a computer application program. The methods independently execute measurement and arrangement procedures. A data structure, sets of executable procedures, and computer-readable media are also provided for facilitating the preparation for presentation of a graphical element.
