Re: Anyone know of a Graphical Timeline Widget?

["Bradley F. Hartman" <hartman mcci-arl-va com>]

In order to implement a timeline widget using the GTK TreeStore, TreeView
and TreeViewColumn classes, I believe I'll have to implement a CellRenderer
to draw the timeline for each task.  The CellRenderers provided by GTK
(Pixbuf, Text and Toggle) will not suffice because I'll have to draw the
timeline using GDK (a Pixbuf will not work). Does anyone know of
any documentation on this subject?  Does anyone have any tips on how
I can accomplish this?


Thanks!

Brad
