One quick follow-up. I re-read [this page][1] about initialization and
realized that I didn't generate or call a `wrap_init` function using `
generate_wrap_init.pl`. So I added that step and am now calling it in
`main()` before any using code. This means that I was previously not
calling the follow
Ok, thanks for trying to help! I'll take a look at the generated code for
something in gtkmm and see if it's any different with regard to ObjectBase
initialization.

It looks like it does, I'm pretty sure this happens in the
`panzoomarea_class_.init()` call:
~~~
PanZoomArea::PanZoomArea()
: // Mark this class as non-derived to allow C++ vfuncs to be skipped.
Glib::ObjectBase(nullptr),
Gtk::DrawingArea(Glib::ConstructParams(panzoomarea_class_.in
How does your generated constructor look? Does it register the new type
with GObject?

I did miss an asterix. Apologies for the transcription error.

Thanks for the suggestion. I tried this

Hello,
I have a custom widget that I've implemented in C and then used gmmproc[1]
to generate C++ bindings for that widget. The process was mostly smooth,
but I cannot seem to use my generated C++ bindings in
Gtk::Builder::get_widget. I can post the full source code if needed, but
probably there i
