Drag and Drop: Influences on the Design of Reusable Software Components

The fundamental unit of large scale software construction is the component. A component is the fundamental user interface object in Java. Everything seen on the display in a java application is a component. The ability to let users drag a component from the Interface and drop into one application is almost a requirement of a modern, commercial user interface. The CBD approach brings high component reusability and easy maintainability, and reduces time-to-market. This paper describes the component repository which provides functionality for component reuse process through the drag and drop mechanism and its influences on the reusable components.
