If I have the following builder markup:
<object class="AdwComboRow">
<property name="expression">
<closure type="gchararray" function="fold_policy_name"/>
</property>
</object>
What would this look like if I were to create it by hand? I have a use-case, but the use of builder is out of scope, so I am having to produce several of these without it. Can someone help?
