Graphical Interface Services for Application Integration
نویسندگان
چکیده
This paper describes a set of graphical object services which provide a cohesive, consistent application development environment for implementing graphical user interfaces in intelligent workstation applications. These objects are implemented as a set of controls using the Presentation ManagerTM windowing system. A control in the Presentation Manager environment is a user interface element with a unique programming interface and application function. This programming interface consists of a series of messages passed between the creating application and the control. The application environment as well as the operating environment of the Presentation Manager is described . The graphical object services are described functionally, as well as architecturally, in order to describe the capabilities of the objects and the necessary detail required to implement new objects . Protocols required to pass extensive amounts of graphical data efficiently between objects in a multi-tasking environment are discussed.

An Interface Formalism for Web Services
Web application development using distributed components and web services presents new software integration challenges, because solutions often cross vendor, administrative, and other boundaries across which neither binary nor source code can be shared. We present a methodology that addresses this problem through a formalism for specifying and manipulating behavioral interfaces of multithreaded...

Applications based on coordination and orchestration of human/system activities are more and more present in our nowadays life. They often need the coherent composition of components, services and data from heterogeneous sources. Moreover, the increasing number of (often conflicting) attributes makes the design of these complex applications very difficult. We tackle the problem of tool integrat...

In this paper, we present our work on the integration of existing engineering applications using Grid Services. We address a visual grid framework that provides an integrated development environment for engineering computation applications. Furthermore, we demonstrate how such services can interact with each other. These interactions enable a level of integration that assists the scientific app...

On-the-fly integration refers to scenarios where a user, say a neuroscientist, wants to integrate a Web Service immediately after discovering it. The challenge is to significantly reduce the required information technology skills to empower the user to focus on the domain-specific problem. Proteus RTI is a first step towards addressing this challenge. It includes a graphical interface to enable...

The World Wide Web has evolved from a distributed hypertext system to a platform-independent graphical user interface that integrates many network services. So far, its technology has restricted it mainly to applications for information retrieval. As networks become ubiquitious and more and more users have a permanent connection, there is an increasing demand for other network services, such as...
