Layout Interfaces for Cluster Graphs ( CGLayoutInterface )

Baseclasses

$\begin{picture}(7,2.5) \thicklines \put(0,1.5){\framebox (6,1){\bf LayoutInter... ...or(0,-1){1}}\put(1,0){\framebox (6.5,1){\bf CGLayoutInterface}} \end{picture}$

Definition

The class CGLayoutInterface extends its base class LayoutInterface by functionality for cluster graphs. Our graphical model for cluster graphs contains the following additional attribute:

a rectangular region of type DPoint for each cluster cl, which bounds the nodes contained in cl.

#include < AGD/CGLayoutInterface.h >

Initialization

CGLayoutInterface A(const ClusterGraph& CG) initializes a layout interface for cluster graph CG.

Operations

const ClusterGraph& A.get_graph() returns the associated cluster graph.

void A.set_cluster_region(Cluster* cl, double x, double y, double width, double height)

sets the region of cluster cl to the rectangular polygon with lower left corner (x, y) and upper right corner (x + width, y + height).

void A.set_graph(const ClusterGraph& CG)

protected method for setting the associated cluster graph to CG.
