Module Hierarchy

• gaphas: Gaphor's Canvas.
  • gaphas.canvas: A Canvas owns a set of Items and acts as a container for both the items and a constraint solver.
  • gaphas.constraint: This module contains several flavors of constraint classes.
  • gaphas.decorators: Custom decorators.
  • gaphas.examples: Simple example items.
  • gaphas.geometry: Geometry functions.
  • gaphas.item: Basic items.
  • gaphas.matrix: Some Gaphor specific updates to the canvas.
  • gaphas.painter: The painter module provides different painters for parts of the canvas.
  • gaphas.quadtree: A quadtree is a tree data structure in which each internal node has up to four children.
  • gaphas.solver: Constraint solver allows to define constraint between two or more different variables and keep this constraint always true when one or more of the constrained variables change.
  • gaphas.sorter: Sorting algorithms and collections for view and canvas.
  • gaphas.state: This module is the central point where Gaphas' classes report their state changes.
  • gaphas.tool: Tools are used to add interactive behavior to a View.
  • gaphas.tree: Simple class containing the tree structure for the canvas items.
  • gaphas.util: Helper funtions and classes for Cairo (drawing engine used by the canvas).
  • gaphas.view: This module contains everything to display a Canvas on a screen.
