-- 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.
