Hi!

If I add it to the constructor:

class studio::ValueBase_Entry : public Gtk::EventBox, public Gtk::CellEditable

{
    Glib::ustring path;
    Widget_ValueBase *valuewidget;
    bool edit_done_called;
    Gtk::Widget *parent;
public:
    ValueBase_Entry():
        Glib::ObjectBase  (typeid(ValueBase_Entry)),
        Gtk::EventBox     (),
        Gtk::CellEditable ()
    {
        Gtk::CellEditable::add_interface(get_type());

...

...

    }

I obtain this after build:

cellrenderer/cellrenderer_value.cpp: In constructor 'studio::ValueBase_Entry::ValueBase_Entry()':
cellrenderer/cellrenderer_value.cpp:86: error: reference to 'get_type' is ambiguous
/usr/include/glibmm-2.4/glibmm/interface.h:67: error: candidates are: static GType Glib::Interface::get_type()
/usr/include/gtkmm-2.4/gtkmm/celleditable.h:100: error:                 static GType Gtk::CellEditable::get_type()
/usr/include/gtkmm-2.4/gtkmm/eventbox.h:87: error:                 static GType Gtk::EventBox::get_type()

So I decided to use the Glib::Interface::get_type() one.

It builds fine and run the application gives:

(synfigstudio:4816): GLib-GObject-CRITICAL **: Object class gtkmm__CustomObject_N6studio15ValueBase_EntryE doesn't implement property 'editing-canceled' from interface 'GtkCellEditable'
(synfigstudio:4816): GLib-GObject-CRITICAL **: g_type_add_interface_static: assertion `G_TYPE_IS_INSTANTIATABLE (instance_type)' failed

Same message for Gtk::CellEditable::get_type()

If I use Gtk::EventBox::get_type()  I obtain:

synfigstudio:6544): GLib-GObject-CRITICAL **: Object class gtkmm__CustomObject_N6studio15ValueBase_EntryE doesn't implement property 'editing-canceled' from interface 'GtkCellEditable'
(synfigstudio:6544): GLib-GObject-CRITICAL **: Object class gtkmm__GtkEventBox doesn't implement property 'editing-canceled' from interface 'GtkCellEditable'
(synfigstudio:6544): GLib-GObject-WARNING **: cannot add interface type `GtkCellEditable' to type `gtkmm__GtkEventBox', since type `gtkmm__GtkEventBox' already conforms to interface

Any idea?

Does it help to call this in your constructor?

Gtk::CellEditable::add_interface(get_type());
