Package y.view Description

Provides essential classes and interfaces for viewing, animating and editing graphs.

The most prominent class in this package is Graph2DView, a Swing component for viewing graphs in two-dimensional space. It displays a Graph2D object, specifically its nodes and edges, but also graphical elements not part of a graph, so-called "drawables" (cf. interface Drawable).

Class DefaultGraph2DRenderer is the default implementation of interface Graph2DRenderer which is used to render the elements inside the view component.
Further classes in this package provide functionality for

• rendering the view component's background,
• the actual visual representation of elements inside the view component: so-called "realizers" for a graph's nodes and edges,
• (mouse-based) user interaction with both the view component itself and also its content: encapsulated in so-called "view modes" that handle things like element creation, but also popup menus,
• application logic (like undo/redo support, printing, print preview, clipboard, etc.).
