Re: Pass more widgets as gpointer.

[Vlad Volodin <vest 84 gmail com>]

Hi, Jens

Yes, your way is good (thank you for a small code, maybe I will use it
in my projects). But, are you sure your way is safe?
You don't know the size of array (at the first),
where do you free the array of pointers itself (try g_malloc and
g_free, because it is GLIB :) ) (at the second).
And I think, your way isn't type-safe (at the third), because you
won't be sure that your element's type is needed.
Well, of course I have many questions and now answers :) I think, in
small projects your way is good (but you can also easily forget the
order of the elements). Maybe HashTables, or STL sets will be more
applicable.

What do you think about all of this?

Good luck in GTK programming :),
