    -- A t'GI.Gtk.Objects.TreeModelFilter.TreeModelFilter' is a tree model which wraps another tree model,
    -- and can do the following things:
    --
    -- * Filter specific rows, based on data from a “visible column”, a column
    --   storing booleans indicating whether the row should be filtered or not,
    --   or based on the return value of a “visible function”, which gets a
    --   model, iter and user_data and returns a boolean indicating whether the
    --   row should be filtered or not.
    -- * Modify the “appearance” of the model, using a modify function.
    --   This is extremely powerful and allows for just changing some
    --   values and also for creating a completely different model based
    --   on the given child model.
    -- * Set a different root node, also known as a “virtual root”. You can pass
    --   in a t'GI.Gtk.Structs.TreePath.TreePath' indicating the root node for the filter at construction
    --   time.
    --
    --
    -- The basic API is similar to t'GI.Gtk.Objects.TreeModelSort.TreeModelSort'. For an example on its usage,
    -- see the section on t'GI.Gtk.Objects.TreeModelSort.TreeModelSort'.
    --
    -- When using t'GI.Gtk.Objects.TreeModelFilter.TreeModelFilter', it is important to realize that
    -- t'GI.Gtk.Objects.TreeModelFilter.TreeModelFilter' maintains an internal cache of all nodes which are
    -- visible in its clients. The cache is likely to be a subtree of the tree
    -- exposed by the child model. t'GI.Gtk.Objects.TreeModelFilter.TreeModelFilter' will not cache the entire
    -- child model when unnecessary to not compromise the caching mechanism
    -- that is exposed by the reference counting scheme. If the child model
    -- implements reference counting, unnecessary signals may not be emitted
    -- because of reference counting rule 3, see the t'GI.Gtk.Interfaces.TreeModel.TreeModel'
    -- documentation. (Note that e.g. t'GI.Gtk.Objects.TreeStore.TreeStore' does not implement
    -- reference counting and will always emit all signals, even when
    -- the receiving node is not visible).
    --
    -- Because of this, limitations for possible visible functions do apply.
    -- In general, visible functions should only use data or properties from
    -- the node for which the visibility state must be determined, its siblings
    -- or its parents. Usually, having a dependency on the state of any child
    -- node is not possible, unless references are taken on these explicitly.
    -- When no such reference exists, no signals may be received for these child
    -- nodes (see reference couting rule number 3 in the t'GI.Gtk.Interfaces.TreeModel.TreeModel' section).
    --
    -- Determining the visibility state of a given node based on the state
    -- of its child nodes is a frequently occurring use case. Therefore,
    -- t'GI.Gtk.Objects.TreeModelFilter.TreeModelFilter' explicitly supports this. For example, when a node
    -- does not have any children, you might not want the node to be visible.
    -- As soon as the first row is added to the node’s child level (or the
    -- last row removed), the node’s visibility should be updated.
    --
    -- This introduces a dependency from the node on its child nodes. In order
    -- to accommodate this, t'GI.Gtk.Objects.TreeModelFilter.TreeModelFilter' must make sure the necessary
    -- signals are received from the child model. This is achieved by building,
    -- for all nodes which are exposed as visible nodes to t'GI.Gtk.Objects.TreeModelFilter.TreeModelFilter'\'s
    -- clients, the child level (if any) and take a reference on the first node
    -- in this level. Furthermore, for every row-inserted, row-changed or
    -- row-deleted signal (also these which were not handled because the node
    -- was not cached), t'GI.Gtk.Objects.TreeModelFilter.TreeModelFilter' will check if the visibility state
    -- of any parent node has changed.
    --
    -- Beware, however, that this explicit support is limited to these two
    -- cases. For example, if you want a node to be visible only if two nodes
    -- in a child’s child level (2 levels deeper) are visible, you are on your
    -- own. In this case, either rely on t'GI.Gtk.Objects.TreeStore.TreeStore' to emit all signals
    -- because it does not implement reference counting, or for models that
    -- do implement reference counting, obtain references on these child levels
    -- yourself.

    -- | Sets the visible function used when filtering the /@filter@/ to be /@func@/.
    -- The function should return 'P.True' if the given row should be visible and
    -- 'P.False' otherwise.
    --
    -- If the condition calculated by the function changes over time (e.g.
    -- because it depends on some global parameters), you must call
    -- 'GI.Gtk.Objects.TreeModelFilter.treeModelFilterRefilter' to keep the visibility information
    -- of the model up-to-date.
    --
    -- Note that /@func@/ is called whenever a row is inserted, when it may still
    -- be empty. The visible function should therefore take special care of empty
    -- rows, like in the example below.
