> Dear developers
>
> I made a patch to add elm_genlist_item_fields_update function.
> It can be used to updating genlist's item part without
realize/unrealize
> itself.
>
> Prototype is
> elm_genlist_item_fields_update
> (Elm_Genlist_Item *it, const char *part,
Elm_Genlist_Item_Field_Flags itf)
>
> Part supports globbing. Passing "*" to part means updating all parts.
> Item field can be one of icon, content and state.
> I think it's useful to speed up if an app updates frequently.
>
> Thanks
