    -- t'GI.Gio.Interfaces.ListModel.ListModel' is an interface that represents a mutable list of
    -- @/GObjects/@. Its main intention is as a model for various widgets in
    -- user interfaces, such as list views, but it can also be used as a
    -- convenient method of returning lists of data, with support for
    -- updates.
    --
    -- Each object in the list may also report changes in itself via some
    -- mechanism (normally the [notify]("GI.GObject.Objects.Object#g:signal:notify") signal).  Taken together
    -- with the [itemsChanged]("GI.Gio.Interfaces.ListModel#g:signal:itemsChanged") signal, this provides for a list
    -- that can change its membership, and in which the members can change
    -- their individual properties.
    --
    -- A good example would be the list of visible wireless network access
    -- points, where each access point can report dynamic properties such as
    -- signal strength.
    --
    -- It is important to note that the t'GI.Gio.Interfaces.ListModel.ListModel' itself does not report
    -- changes to the individual items.  It only reports changes to the list
    -- membership.  If you want to observe changes to the objects themselves
    -- then you need to connect signals to the objects that you are
    -- interested in.
    --
    -- All items in a t'GI.Gio.Interfaces.ListModel.ListModel' are of (or derived from) the same type.
    -- 'GI.Gio.Interfaces.ListModel.listModelGetItemType' returns that type.  The type may be an
    -- interface, in which case all objects in the list must implement it.
    --
    -- The semantics are close to that of an array:
    -- 'GI.Gio.Interfaces.ListModel.listModelGetNItems' returns the number of items in the list and
    -- @/g_list_model_get_item()/@ returns an item at a (0-based) position. In
    -- order to allow implementations to calculate the list length lazily,
    -- you can also iterate over items: starting from 0, repeatedly call
    -- @/g_list_model_get_item()/@ until it returns 'P.Nothing'.
    --
    -- An implementation may create objects lazily, but must take care to
    -- return the same object for a given position until all references to
    -- it are gone.
    --
    -- On the other side, a consumer is expected only to hold references on
    -- objects that are currently \"user visible\", in order to facilitate the
    -- maximum level of laziness in the implementation of the list and to
    -- reduce the required number of signal connections at a given time.
    --
    -- This interface is intended only to be used from a single thread.  The
    -- thread in which it is appropriate to use it depends on the particular
    -- implementation, but typically it will be from the thread that owns
    -- the [thread-default main context][g-main-context-push-thread-default]
    -- in effect at the time that the model was created.
