Cairo-specific abstract edge drawer object.

Method __init__ Constructs the edge drawer.
Method draw_loop_edge Draws a loop edge.
Method draw_undirected_edge Draws an undirected edge.
Instance Variable context Undocumented
Instance Variable palette Undocumented
Instance Variable VisualEdgeBuilder Undocumented
Method _construct_visual_edge_builder Construct the visual edge builder that will collect the visual attributes of an edge when it is being drawn.

Inherited from AbstractEdgeDrawer:

Method draw_directed_edge Draws a directed edge.
Method get_label_position returns the position where the label of an edge should be drawn. the default implementation returns the midpoint of the edge and an alignment that tries to avoid overlapping the label with the edge.
Method get_label_rotation Get the rotation angle of the label to align with the edge.
Static Method _curvature_to_float Converts values given to the 'curved' edge style argument in plotting calls to floating point values.
def __init__(self, context, palette):

Constructs the edge drawer.

Parameters
contexta Cairo context on which the edges will be drawn.
palettethe palette that can be used to map integer color indices to colors when drawing edges
def draw_loop_edge(self, edge, vertex):

Draws a loop edge.

The default implementation draws a small circle.

Parameters
edgethe edge to be drawn. Visual properties of the edge are defined by the attributes of this object.
vertexthe vertex to which the edge is attached. Visual properties are given again as attributes.
def draw_undirected_edge(self, edge, src_vertex, dest_vertex):

Draws an undirected edge.

The default implementation of this method draws undirected edges as straight lines. Loop edges are drawn as small circles.

Parameters
edgethe edge to be drawn. Visual properties of the edge are defined by the attributes of this object.
src_vertexthe source vertex. Visual properties are given again as attributes.
dest_vertexthe target vertex. Visual properties are given again as attributes.
