I am creating a grid like treeview, using liststore as the model. So, I  
set the row to the grid row and each col to the grid column. So, I can  
easily get the cell(row, col) using hte listore.

After showing the treeview, I found that I can’t allow the user to  
select single cell, they only allow to select single row. How can I  
change this behaviour? I already try all the Treeview#selection mode but  
neither meet my requirement.

I am thinking to use the treestore and map the row to a parent and all  
the column to a child. But I still have problem on showing its  
appearance as a gridview.

Can anyone help me on this? I just want to make a simple grid view but  
It seems really hard to do using GTK. I can done it easily with the C#  
GridView but not on this Gtk. May be WxRuby is easier to draw a grid  
view?

The fundamental problem is GtkTreeView does _not_ support grid  
selection. This is why programs like Gnumeric, etc implement their own  
custom grid widget. It’s one of the most requested missing  
widget/feature in gtk+, IMHO.
