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.

Keywords
classes
Objects from the Class

Objects can be created by calls of the form new("AgNode", ...).

Slots

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.

Methods

color
signature(object = "AgNode"): Retrieves the drawing color for the node.
fillcolor
signature(object = "AgNode"): Retrieves the color to fill in the node image with.
getNodeCenter
signature(object = "AgNode"): Returns the center point of the node.
getNodeXY
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.
getNodeHeight
signature(object = "AgNode"): Returns the height of the node.
getNodeLW
signature(object = "AgNode"): Returns the left width of the node.
getNodeRW
signature(object = "AgNode"): Returns the right width of the node.
name
signature(object = "AgNode"): Retrieves the name of the node.
shape
signature(object = "AgNode"): Returns the shape of the node.
style
signature(object = "AgNode"): Returns the style of the node.
txtLabel
signature(object = "AgNode"): Retrieves the node label.
