using advanced but crucial functionalities of Draw2D library like the link connection betweenobjects in the work area.Figure 3.4 – Architecture of an example applicationBefore choosing this library for our project we have analyzed some example of realizedapplication, the API documentation and the main classes to see the structure and we have alsotested it practically. The main functionalities available in the library are the following:Generation of shapes and figures inside the work areaUse of connection ports (input / output) to connect objects with linksPersonalization of linksDrag and Drop functionalityUndo / Redo functionalityDelete objects functionalityPan function to move the diagram in the work areaCommand management functionalities to add, connect, delete, move, …Dynamic editing of objects (figures and connections) name and properties, for exampleusing dropdown menu to edit the properties or to connect other objectsPossibility to associate images to a figure (to represent different type of objects, forexample to represent a database, a service or other)Use of compartment figures, figures which can contain other figures or objects (forexample to create forms)22
Possibility to use dynamic windows (property windows and dialog windows) to managethe environment, the work area and the diagramUse of a tool palette window to add figures to the work areaTooltip functionality for the objectsUse of dropdown menusPossibility to use XML format to represent the diagramPossibility to implement a zoom instrument (in development phase)Possibility to create HTML forms in dialog windowsIdentity for JavaScript objects with an automatic unique Id method generation. Theidentity for an object does not change during its lifecycleManagement system for eventsThe class hierarchy of the library is complex and not simple to read, in the following diagrams wewill show a reduced Object Oriented view which represents all kinds of figures, lines andcommands on them which can be used with Draw2D.Figure 3.5 – Draw2D figures class hierarchy23
