Re: How to make a single cell editable in Gtk::TreeView?

[Kjell Ahlstedt <kjell ahlstedt bredband net>]

The attached file is a modified version of  the treeview/editable_cells 
example in the gtkmm tutorial.
I've added a bool column to the tree model, and connected it to the 
"editable" attribute of two TreeView columns.
Search for "//!!". It shows where I've modified the 
treeview/editable_cells example in the gtkmm tutorial. See also 
http://mail.gnome.org/archives/gtkmm-list/2012-February/msg00041.html 
where I show how to grey out one choice in a ComboBox. It's the same 
technique. Use Gtk::CellLayout::add_attribute() in a combo box, or 
Gtk::TreeViewColumn::add_attribute() in a tree view.
