Re: [gtkmm] Is it possible to handle Double-click event on the tree columns?

[Matthew Walton <matthew alledora co uk>]

Firstly, please use 'Reply to All' when replying to a mailing list.

Working examples can be found in the gtkmm source distribution in the 
gtkmm-demo, where you'll find code which allows double-clicking on the 
examples in a TreeView to launch them. There is a lot of example code 
supplied with gtkmm, and a lot of it is extremely useful.
