This splits GtkListItem into 2 parts: 1. GtkListItem This is purely a GObject with public API for developers who want to populate lists. There is no chance to cause conflict with GtkWidget properties that the list implementation assumed control over and defines a clear boundary. 2. GtkListItemWidget The widget part of the listitem. This is not only fully in control of the list machinery, the machinery can also use different widget implementations for different list widgets like I inted to for GtkColumnView.
