c++

[Daniel S. Haischt]

Gert Cuykens,

I would suggest to post such questions to gtk-list at gnome.org,
because IIRC you are trying to code a GTK app ...

Additionally I would suggest to learn C/C++ first to get a better
understanding of the whole language structure. Or at least please
join the c# IRC channel at irc.freenode.net to ask such questions,
it's quite annoying to see them on a list which is dedicated to an
UNIX OS.
