摘要:
Displaying a plurality of objects on a grid. Metadata indicates an object's display column and span. A lowest position is determined from objects displayed in the same column span. The object is displayed in the column span at the lowest position. A lowest position is determined after the last object is displayed. The grid is resized to minimize whitespace beyond the lowest position to border whitespace. Display overlay of first and second graphical objects. When the first object is directly manipulated in a GUI, the second object is automatically manipulated the same way. When the first object is scrolled in a first direction by a first amount, the second object is automatically displaced opposite the first direction by the first amount. When the first object is resized in a first dimension by a first amount, the second object can be automatically resized by the first amount in the first dimension.

Various embodiments of systems and methods for integrated metadata and nested authorizations in a user interface framework are described herein. User interface components metadata and authorization metadata are stored in one integrated entity. The primary user interface application components have authorization metadata and are checked at runtime for accessibility to the user interface application for a given user. The user interface framework ensures the security of the embedded user interface components via nested authorizations using metadata relations. The metadata relations are used for runtime authorization and policy generation. Generic user interface components are aggregated at runtime.

Various embodiments of systems and methods for improved user interface framework for Web applications are described herein. The UI framework is based on the MVC architectural pattern. An additional controller, a server controller, is included in the server part of the user interface framework runtime. A client controller is running at the client side of the user interface framework runtime. The client controller and the server controller form one logical synchronized controller. The server controller ensures that all needed controller calculations, which would lead to additional roundtrips between the client side and the server side, can be done on the server side. Thus, exact one roundtrip between client side and backend for every user interaction and transporting only the bare minimum of data needed to render the current UI state is achieved.

A computer system can include a data handler configured to receive data for display within a plurality of layout elements. Each layout element from the plurality of layout elements can be identified for display within an application. The computer system can include a boundary generator configured to associate a first plurality of variable-size fields with a first column and associate a second plurality of variable-size fields with a second column. Each layout element from the plurality of layout elements can include at least one variable-size field from the first plurality of variable-size fields and at least one variable-size field from the second plurality of variable-size fields. The boundary generator can be configured to define a pair of alignment boundaries using a predicted size of each of the variable-size fields from the first plurality of variable-size fields.

Methods for synchronizing data in client-server architectures are described. A client stores data in first and second fields. The value stored in the second field depends on the value stored in the first. When the client writes a new value to the first field, it disables writing to the second field. The client sends a refresh request and receives a refresh response from a server. The refresh request and response contain differences in data stored in the client and server fields. If the refresh response includes a new value for the second field, the client writes the value to the second field. A round trip pending flag associated with the first field is set. A data invalid flag associated with the second field is set. New data can be written to a third field when the value of the third field does not depend on the value of the first field.

Various embodiments of systems and methods for a composition model for components of a user interface framework for Web applications are described. The methods include a loosely coupled method and a tightly coupled method for composing components in a UI framework. The loosely coupled method includes triggering a navigation pipe from an out-port of a first component to an in-port of a second component and defining a context mapping between a first set of parameters of the out-port of the first component and a second set of parameters of the in-port of the second component. The tightly coupled method includes exposing a binding reference from the first component to the second component and specifying a first data model entity from the first component to be bound to a second data model entity of the second component via a binding contract.

Methods and apparatus for displaying objects in client GUI. A lead selection and scoping information is used to determine whether the object is viewable, and the object is rendered only if it is at least partially viewable. The lead selection and scoping information is used to determine whether data is needed to render the object, and data is received from a corresponding object on a server only if it is needed to render the object. Determining whether the object is viewable in the GUI can be based on declaratively marked entities within the object's view and on view calculation rules. Determining whether data is needed to render the object can be based on declaratively marked entities within the object's data model such as flags indicating whether the data field is valid or whether the binding of the data field to a data source is valid.

A computer system includes a UI designer client that runs on a client device and is configured to enable creation of UI models. A client engine runs on a client device and is configured to initiate requests for the UI models, receive the UI models in response to the requests and interpret and render the UI models at runtime. A UI runtime server client is located on a server and is configured to interface with the client engine to receive and process the requests for the UI models from the client engine. A repository is located on the server and is configured to interface with the UI designer client and store the UI models as created using the UI designer client and interface with the UI runtime server client to deliver requested UI models to the UI runtime server client for interpretation and rendering by the client engine.
摘要:
A component object binds business driven services to a graphical user interface (GUI). The object includes a data model, view model and controller. The view model graphically presents, and the controller manipulates data used by the object. The controller includes an event handler that respond to events generated within the GUI and binds data used by the object to a data source which can be another component object or a remotely located source. The event handler can call a local script to calculate the value of a data element within the object. The component object can be instantiated on a client, and can be configured to communicate with a corresponding component object on a server. The client and server component objects can exchange only that data that needs to be exchanged to maintain the current state of a user interface in the client computer.
