Re: Pass more widgets as gpointer.

[Vlad Volodin <vest 84 gmail com>]

Hello, Jens

The other way is to make your widgets global. Especially, me? I use
GOjects, and always pass "self" object. For example, I inherit  main
window object from GtkWindow and later in widgets definition pass
itself to callback. Also, you can use g_object_set_data for storing
some useful pointers.

Good luck
