Re: [gtkmm] TreeView/ListStore

[Daniel Sundberg <dss home se>]

If you still don't know how to do this you could have a look at two of my source files:

plothistory.h
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/gspeakers/gspeakers2/src/plothistory.h?rev=HEAD&content-type=text/vnd.viewcvs-markup

plothistory.cc:
http://cvs.sourceforge.net/cgi-bin/viewcvs.cgi/gspeakers/gspeakers2/src/plothistory.cc?rev=HEAD&content-type=text/vnd.viewcvs-markup

In bottom of the cc-file i do something like people have tried to explain to you. Maybe it is easier if you have real working source code to look at.

Mail me if you have problems understanding my code.
