Thanks Kjell, you have a good eye. I tried making the change to
`_CLASS_GTKOBJECT` but I'm not sure what else needs to change. On my system
`class_gtkobject.m4` is installed at
`/usr/lib/x86_64-linux-gnu/gtkmm-3.0/proc/m4`, so I tried the following
execution of gmmproc but the generated .h file is mostly empty:
~~~
M4PATH=/usr/lib/x86_64-linux-gnu/gtkmm-3.0/proc/m4:/usr/lib/x86_64-linux-gnu/glibmm-2.4/proc/m4
/usr/lib/x86_64-linux-gnu/glibmm-2.4/proc/gmmproc -I
/usr/lib/x86_64-linux-gnu/glibmm-2.4/proc/m4 -I
/usr/lib/x86_64-linux-gnu/gtkmm-3.0/proc/m4 panzoomarea mm mm
~~~
The generated `panzoomarea.h` looks broken:
~~~
// Generated by gmmproc 2.56.0 -- DO NOT MODIFY!
#ifndef _TANGENT_GTKUTIL_MM_PANZOOMAREA_H
#define _TANGENT_GTKUTIL_MM_PANZOOMAREA_H
#include <glibmm/ustring.h>
#include <sigc++/sigc++.h>
// clang-format off
// clang-format on
#include <glibmm.h>
#include <gtkmm/drawingarea.h>
namespace Gtk {
#endif /* _TANGENT_GTKUTIL_MM_PANZOOMAREA_H */
~~~
here is the full `panzoomarea.hg`:
~~~

Gtk::DrawingArea, GtkDrawingArea)

_WRAP_SIGNAL(bool area_draw(const ::Cairo::RefPtr< ::Cairo::Context>& cr),
"area-draw");
// clang-format on

_WRAP_PROPERTY("offset-y-adjustment", Glib::RefPtr<Gtk::Adjustment>);

_WRAP_PROPERTY("active", bool);
_WRAP_PROPERTY("pan-button", int);
_WRAP_PROPERTY("demo-draw-enabled", bool);
};
} // namespace Gtk

Is there something else I need to make the `_CLASS_GTKOBJECT` macro work?
Thanks for the help,
Josh
