I have compiled code that generates a two column list store with gtk2. I  
have enabled one column to be editable but I cannot figure out how to  
store the data that I type into the cell. Every time I enter a number  
into the cell and press enter it goes back to zero.

Here is a sample of the code:

```
@nodeListStore = Gtk::ListStore.new(String)
@destListStore = Gtk::ListStore.new(String,Integer)

@costRender = Gtk::CellRendererText.new.set_editable(true)

@nodeCol = Gtk::TreeViewColumn.new("Node Name",

```

Gtk::CellRendererText.new, :text=\>0)  
@destCol = Gtk::TreeViewColumn.new(“Destinations”,  
Gtk::CellRendererText.new, :text=\>0)  
@costCol = Gtk::TreeViewColumn.new(“Cost”,@costRender,:text=\>1)

```
@nodeTreeView = Gtk::TreeView.new(@nodeListStore)
@nodeTreeView.append_column(@nodeCol)
@nodeTreeView.selection.set_mode(Gtk::SELECTION_SINGLE)

@destTreeView = Gtk::TreeView.new(@destListStore)
@destTreeView.append_column(@destCol)
@destTreeView.append_column(@costCol)
@destTreeView.selection.set_mode(Gtk::SELECTION_SINGLE)

```

Any Suggestions

Maybe you need this:  
[http://ruby-gnome2.sourceforge.jp/hiki.cgi?cmd=view&p=Gtk%3A%3ACellEditable&key=editable](http://ruby-gnome2.sourceforge.jp/hiki.cgi?cmd=view&p=Gtk%3A%3ACellEditable&key=editable)

Anyway, you can find plenty of samples in the distro…

You must write the data to the model in Gtk::CellRendererText’s edited  
signal

See
