[pygtk] Sharing a CellRenderer among two or more columns

[Stéphane Brunet]

Hi,

I am working on TreeViews using a ListStore model but I couldn't find 
any answer on this yet:

Say I have a ListStore with 4 columns containing strings. They are all 
be rendered by a CellRendererText object in a separate TreeViewColumn. I 
have tried to use a single instance of CellRendererText assigned to each 
TreeViewColumn and it worked great.

However, when I want to make each column editable, how do I specify the 
callback function to the CellRendererText object so that it will know in 
which column to put the new text ? Am I compelled to use a separate 
instance of CellRendererText for each column ?

Thank you,

Stéphane
