\brief There are currently 2 visually different types of EdgeArrow%s used in the graph. Even though they are drawn differently, both are functionally

\brief Baseclass for all edges in the Scene with most of the actual code for displaying the QGraphicsObject. The Edge Label -------------- The EdgeL

\brief The base class for round edges in the graph: PlugEdge and DrawEdge. Other than the StraightEdge branch of the inheritance tree, this class use

\brief Container class for a collapsible display widget and a title button.

\brief Edge used to draw a new edge. It is a specialized BezierEdge, as it does not have an end Plug and is only used to visually create a PlugEdge i

\brief The EdgeArrow is an additional item of the BaseEdge, identifying its direction. It is placed at the middle of the BaseEdge and comes in two fl

\brief An EdgeGroup is an additional layer of management for all PlugEdge%s between two Node%s. Its main function is to display a single edge, if bot

\brief Mix-in interface for EdgeGroup and EdgeGroupPair. This is necessary to mirror the inheritance tree of StraightEdge and StraightDoubleEdge. Now

\brief A pair of EdgeGroup%s, both connecting the same Node%s but in different directions. While a single EdgeGroup contains 1-n PlugEdge%s, an EdgeG

\brief The label of a BaseEdge. EdgeLabel%s are only visible, when the mouse is hovering the BaseEdge or EdgeArrow.

\brief Controller Manager managing all NodeCtrls. This is the main class for controlling the business logic of the application.

\brief A single instance of this class contains all other widgets of the application. It also contains the node Manager that in turn controls the bus

\brief Controller class for managing a single node in the graph.

\enum NodeExpansion Describes, whether the incoming or the outgoing Plug%s of a Node are displayed -- or both or none. Note that the state change is

\brief Label of a Node. The horizontal rounded rectangle in the center of the Node core, containing the display name of the Node as label.

\brief Node Property widget, is a display widget of a Collapsible.

\brief Perimeter around the Node, only appears once mouse has entered the Node.

\brief A single Plug of a Node. Plug%s are managed by their respective Node and should not be tempered with directly.

\brief The direction in which a Plug leads in relation to its Node.

\brief A PlugEdge in the Zodiac Graph connecting two Plug%s of different Node%s. This is the main edge class in the graph. However, most of its funct
