Re: Gtk2 Treeview/Simplelist and set_tooltip_row()

[zentara]

Just for a quick hack check, I substituted in the code from the treeview tooltip example link from my previous response, derived the model from the $catagories SimpleList, and it seems to work( some minor problems to work out like popup position, columns not existing, and what to do with selected rows. Here it is if you care to work out the bugs, I'm lazy today. :-)
