I just don't think you should do that. You need to fix your code generator.
(Not that I think anyone should use a code generator).
This is like having different add() functions with different parameters. It's
OK, even if it's unnecessarily inconsistent. We can't change it now anyway
without breaking ABI.
You might file a bug about the inconsistency with GTK+, in case they ever do a
GTK+ 3.0 version.

> with functions that take a Callback as argument
If a) The callback would only be used for the lifetime of that function call,
just destroy it yourself afterwards. For instance *_foreach().
If b) The callback would be called only once, destroy it at the end of the
callback.
If c) the callback would be called several times after the function has
returned, destroy it in the destroy_func callback. If there is no destroy_func
parameter, file a bug. For instance *_cell_data_func().

the behavior of Gdk::Rectangle::itersect is very surprising.
if you have two rectangles A and B, and you do the following:
Gdk::Rectangle C = A.intersect (B);
Then C will be equal to the intersection of the two rectangles, but
surprisingly, A will also be changed so that it is equal to C. The
implementation in rectangle.ccg is as follows:
Rectangle& Rectangle::intersect(const Rectangle& src2)
{
gdk_rectangle_intersect(
&gobject_, const_cast<GdkRectangle*>(&src2.gobject_), &gobject_);
return *this;
}
So the underlying GTK+ API allows you to calculate an intersection without
modifying the original rectangle (A), but the gtkmm API does not -- it forces
you to modify A. I would have rather expected the implementation to be
something like this:
Rectangle& Rectangle::intersect(const Rectangle& src2)
{
Gdk::Rectangle intersection;
gdk_rectangle_intersect(
&gobject_, const_cast<GdkRectangle*>(&src2.gobject_),
intersection.gobj());
return intersection;
}
I suppose this can't be changed now since there's probably an app somewhere
that depends on the current behavior, but it might be worth considering for
when we can break API.

In C Gtk+, you can do the following:
if (gdk_rectangle_intersect (a, b, c))
{
// the rectangles intersect
}
in gtkmm you can do this, but it is rather cumbersome:
bool rectangles_intersect;
c = a.intersect(b, rectangles_intersect);
if (rectangles_intersect)
{
// the rectangles intersect
}
if Gdk::Rectangle had an operator bool() which returned true if the rectangle
was non-empty, it would make this less clumsy, e.g.:
if (c = a.intersect(b))
{
// the rectangles intersect
}
