[zvtm-devel] Tooltip feature request

[Chuck F. <cf...@gm...>]

Hi all,
First off, zgrviewer is a great program, its the only one that I've seen
capable of actually displaying
a graph with > 100 nodes with any performance :)
I have a feature request that I would also be willing to work on with a
little more direction. As you all
know the nodes/edges in graphs can have URLs assigned to them that you can
click on to pop up
the web browser. Graphviz also allows you to embed tooltips which pop up
when a mouse-over occurs
in a web browser over an edge/node.
For graphs that are small enough to be displayed in Firefox this works with
SVG files and can be very useful for embedding more information about
edges/nodes that can interactively pop up.
My question is, how difficult would it be to add the mouseover events to
zgrviewer so that the tooltip
data could be displayed in the same way?
Thanks for your help,
Chuck
