C++ Interfaces for GTK+ and GNOME
C++ Interfaces for GTK+ and GNOME
The mailing lists are used for discussion of development, bug reports, suggestions, and improvements of the C++ wrappers themselves. There is also discussion of the use of the wrapper. Questions about the underlying GTK+ widget set are more likely to be answered quickly through the gtk-list.
The archive of messages can be found at:
MARC archives messages even from before 2002, and has a more reliable search engine.
We also discuss development in the #c++ channel on irc.gnome.org, but questions are more likely to be answered properly on the mailing list. Plus, the mailing list is archived, so others can benefit from the answers.
