Re: 2. Re: General tips about GTK+ programming

[Dov Grobgeld <dov grobgeld gmail com>]

First of all, since C++ is basically a superset of C, you can add as much or
little C++ as you want to your C-program. In another word, you can program
in C++, but use the C-api for widget creation, etc. That is what I have been
doing e.g. in my projects GemTCL and giv. In contrast to what was said in
this thread, I am subclassing GtkWindow and adding private members to it,
and am doing it in C. But, as I also find the C-syntax very tough and
verbose for object inheritance, I have been using gob2 for this. gob2 is a
preprocessor written for extending and dealing with GObjects.

It may be claimed that gob2 has become deprecated with the emergance of
Vala, which is a new language that compiles to C/H-code for GObjects. But
then you are no longer writing in C or C++ at all, for good and for bad.
It's pluses is that its syntax is much nicer for GObjects. Its minuses is
that you need to create extra glue interfaces in order to refer to other C
and C++ classes.

Hope this helps.

Dov
