[gtkmm] Automatically-stored editable cells

[Kjell Irgens <kjell spacetec no>]

Hi,

I have a simple window with which contains a Treeview with editable columns
and OK/Cancel buttons.  The users of the program tend to change the contents
of a single cell and then press OK without pressing e.g. return first.  The
result is that the model does not change.

Any suggestions on how to solve this? I am using Gtkmm 2.0.
