Class "AgNode": A class to describe a node for a Ragraph object
This class is used to represent nodes for the
Ragraph class. One can retrieve various pieces of information
as well as draw them.
Objects can be created by calls of the form new("AgNode", ...).
center:Object of class "xyPoint": The center
point of the node
name:Object of class "character": The name of
the node, used to reference it
txtLabel:Object of class "AgTextLabel": Label
for this edge
height:Object of class "integer": Height of
the node in points
rWidth:Object of class "integer": The right
half of the node in points.
lWidth:Object of class "integer": The left
half of the node in points.
color:Object of class "character": The drawing
color of the node.
fillcolor:Object of class "character": The
color to fill in the node with.
shape:Object of class "character": The shape
of the node.
style:Object of class "character": The style
of the node.
signature(object = "AgNode"): Retrieves the
drawing color for the node.
signature(object = "AgNode"): Retrieves the
color to fill in the node image with.
signature(object = "AgNode"): Returns
the center point of the node.
signature(object = "AgNode"): Returns the
center as a two element list, with the first element containing
the 'x' value and the second element containing the 'y' value.
signature(object = "AgNode"): Returns
the height of the node.
signature(object = "AgNode"): Returns the
left width of the node.
signature(object = "AgNode"): Returns the
right width of the node.
signature(object = "AgNode"): Retrieves the name
of the node.
signature(object = "AgNode"): Returns the shape
of the node.
signature(object = "AgNode"): Returns the style
of the node.
signature(object = "AgNode"): Retrieves the
node label.
