[Gtk-sharp-list] Treeview Tooltip for each Row

[Nicolas Krzywinski]

Hi Sven,

I ran into the exact same problem and found out how to solve it, try:

	int binX;
	int binY;
	trvMainCuesheet.ConvertWidgetToBinWindowCoords(args.X, args.Y, out binX, out binY);

and then something like..

	if (trvMainCuesheet.GetPathAtPos (binX, binY, out path, out col) && trvMainCuesheet.Model.GetIter (out iter, path))
	{
	    YourType YourVar = (YourType)trvMainCuesheet.Model.GetValue (iter, 0);
		...
	}

Good luck!
Nicolas
