[gtkmm] Treeview and text editing with a double click

[Diana Esch-Mosher <desch-mosher lanl gov>]

Hi,

I am successfully capturing the signal_edited() for a text entry column.
I have other (i.e. pixbuf) columns that capture the double click for
specific processing. I want to know if there is an "easy" way to modify
the behavior of the text entry to invoke editing that I can capture for
processing on a double click rather than a single click. I prefer to
have all my columns have the same activation mechanism of the double
click!
