But if it turns out to be one (because changing the model is expensive), then you might want to delay changes to the model. You can do that for example by not connecting to 'changed' but instead apply the changes when the dialog is closed. Or you could connect to 'activate' and 'leave-notify-event' and apply the change when the user presses Enter and when the focus leaves the entry. > 2.

You want to connect to the 'edited' signal of the GtkCellRendererText object that is responsible for rendering the editable cell.
