My standard method (not necessarily the best, but it works nicely for
me) is to create a class (call it AppGTK) that has all the widgets as
private data members. The callbacks are static member functions of
the class (solves your problem below). I then have one global
variable app_gtk. In each callback, I can then access any of the
widgets using that global variable and since the callbacks are members
of the class, they can legally access all the private data.
