使用GSettings时，{ss}应该映射到哪种GLib类型？

Question

I have a gsettings schema with a key of type a{ss} . I would like to bind said key to a property on an object. I have successfully used g_settings_bind and g_settings_bind_with_mapping with other keys but I don't know what type to map this key to. The GVariant is an array of dictionaries with key string and value string, but what accual glib type is that?

Answer 1

You need to use g_settings_bind_with_mapping() , since a{ss} is not supported by g_settings_bind() . a{ss} is a dictionary mapping strings to strings, and I would probably represent it in GLib as a GHashTable mapping strings to strings.
