GtkTreeView get selected row AND column

[Juan Pablo <jpdborgna yahoo com ar>]

Hi list!
I have a GtkTreeView and what I want to do is when the user is over an
editable cell, the editing begins automatically without having to press
enter. And the other thing that i want to do is that when the user is
over a cell on a certain column the cursor changes automatically to the
next (he cant edit that cell).

The GtkTreeView is a ticket editor, when the user is on the first
column, the editing should be started automatically so he puts a product
code, then when he press enter, the second column is filled with the 
description of the product wich has that code and the third column
should get the focus, where, again without having to press enter, he
inputs the amount and then it jumps to the first column on the next row.

This is why i need to know the row and column, so in the cursor_changed
signal i can decide to emmit start_editing or to pass the focus some
where else.

If is any other way to do it, please! :D

Thanks all.


Saludos, Juan Pablo.
