5 Graph Description Language (GDL) - Absint

AISEEICONS can be set to the directory containing the bitmap file. For details on pictures
in nodes, see p. 106.
• importance
Type: integer
Default value: 0 (which means infinity)
Attribute of: node
Description:
This is the central attribute when it comes to filtering in fish-eye views as it enables the
importance of a node to be specified via an integer. Low integers signify less important
nodes which are filtered out first by a filtering fish-eye view. High integer numbers signify
nodes that are important, their being rarely filtered out. A value of 0 represents an infinite
importance, the result being that these nodes are never filtered out. This attribute also exists
for summary nodes of folded subgraphs, see importance (p. 74).
• info1, info2, info3
Type: string
Default value: empty string for all three
Attribute of: node
Description:
These attributes enable three additional text fields to be specified for a node. The same set
of attributes exists for summary nodes (see node attribute info1, p. 75). These additional
information fields can be selected interactively from the submenu of the Information menu
(see p. 19).
When exporting a graph to SVG (or HTML), a URL can be specified in the info3 field of a
node that is visited when the user clicks on that node in the SVG (or PNG or BMP) image.
The URL specification has to be in the format info3: "href:URL", meaning that if the
content of an info3 field does not start with href:, it will be interpreted as a normal
information field rather than as a hyperlink.
In addition to a URL, the following optional hyperlink attributes can be specified:
– target
– onMouseOver
– onMouseOut
– onMouseDown
– onMouseUp
– onMouseMove
– onClick
These attributes can be specified in any order directly after the URL itself. The specifications
must be separated by semicolons. Examples:
info3: "href:http://www.aisee.com/svg/"
info3: "href:javascript:myfunction(42,’Hello world!’)"
info3: "href:http://www.aisee.com;target:_blank;onClick:foo(’bar’)"
