FI, I have posted a patch implementing this in gtk on

https://gitlab.gnome.org/GNOME/gtk/issues/109

Along the way, I found that there is

    <child internal-child="accessible">
            <object class="AtkObject">
                    <property name="AtkObject::accessible-role">ATK_ROLE_STATIC</property>
            </object>
    </child>

which is supposed to do the same, but that doesn't work:
"accessible-role" is supposed to be an int, not a string, and thus one
would have to put 117 there instead of ATK_ROLE_STATIC, which is really
going to work :)


This is a bug in atk, I would say. The role property should really be defined as enum, not as int.
If that is fixed, then your ui file snipplet will start to work.
