           Summary: Documentation suggestion for Gtk2::TreeView - path
                    strings
           Product: gnome-perl
           Version: unspecified
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: Normal
         Component: Gtk2

Path strings (as used by Gtk2::TreePath) are not explained in the perl
documentation for gtk2. Here's my notes; the first paragraph is mostly
cribbed from the Ruby docs, IIRC. The second paragraph was written by me,
and is hopefully true. :)

Path strings are expected to be a colon separated list of numbers. For
example, the string "10:4:0" would create a path of depth 3 pointing to the
11th child of the root node, the 5th child of that 11th child, and the 1st
child of that 5th child. If an invalid path string is passed in, an error
results.

Usually, in a TreeView, you should be looking at depth 1 or 2 path strings.
If your TreeView consists of a single column, then the path string for the
cell in the first row is "0", the second row is "1", and so on. A
multi-column (but still an ordinary, two-dimensional) TreeView would have
"0:0" as the cell in the upper, left-hand corner, "0:1" for the cell to its
right, and "1:0" for the cell below it.

In the original .pod for Gtk2::TreeView, we have:
(path, column, cell_x, cell_y) = $tree_view->get_path_at_pos ($x, $y)
 
 * $x (integer)
 * $y (integer)
 In scalar context, returns the Gtk2::TreePath, in array context, adds the
 Gtk2::TreeViewColumn, and $x and $y translated to be relative to the cell.
I believe that $x and $y are pixel coordinates. This should be made more
clear. Possibly I am wrong, in which case, the truth should still be made
more clear. :)
