A component (or proclet) is the building block of the VisualAp environment. A component is shown with its icon plus a number of terminals. Terminals are represented by a small blue square. Terminals are also called pins. Input terminals are placed in the left side of a component, while output terminals are placed in the right side of a component.

Using components
It is possible to view/modify the configuration of a component by double-click over a component in the workplace panel. Components can be connected together by first pressing the mouse button over a terminal, then move the mouse pointer over another terminal and then release the mouse button: an edge between the two terminals is created.

The following rules must be followed when connecting a terminal to another one:
  • it is not possible to connect together two or more output terminals
  • any input terminal must be connected to an output terminal
  • loops and cycles are not allowed in a system
These errors are detected only when the system is checked (System->Check)
It is possible to design and release new components for VisualAp. please read the related developer guide.

New components shall be placed in the <beans> directory under the VisualAp directory.
