<a name="line-31"></a><span class='hs-comment'>--</span>
<a name="line-32"></a><span class='hs-comment'>-- | The 'TreeModel' interface defines a generic storage object for use by the</span>
<a name="line-33"></a><span class='hs-comment'>-- 'TreeView' and similar widgets. Specifically, the functions in defined here</span>
<a name="line-34"></a><span class='hs-comment'>-- are used by Gtk's widgets to access the stored data. Thus, rather than</span>
<a name="line-35"></a><span class='hs-comment'>-- calling these functions, an application programmer has to implement them.</span>
<a name="line-36"></a><span class='hs-comment'>-- While the module "Graphics.UI.Gtk.ModelView.CustomStore" provides the</span>
<a name="line-37"></a><span class='hs-comment'>-- necessary functions to implement the 'TreeMode' interface, it is often</span>
<a name="line-38"></a><span class='hs-comment'>-- sufficient to use the wo implementations that come with Gtk2Hs, namely are</span>
<a name="line-39"></a><span class='hs-comment'>-- 'ListStore' and 'TreeStore'.</span>
<a name="line-40"></a><span class='hs-comment'>--</span>
<a name="line-41"></a><span class='hs-comment'>-- The model is represented as a hierarchical tree of values. It is important</span>
<a name="line-42"></a><span class='hs-comment'>-- to note that this interface only provides a way of examining a model and</span>
<a name="line-43"></a><span class='hs-comment'>-- observing changes. The implementation of each individual model decides how</span>
<a name="line-44"></a><span class='hs-comment'>-- and if changes are made.</span>
<a name="line-45"></a><span class='hs-comment'>--</span>
<a name="line-46"></a><span class='hs-comment'>-- Two generic models are provided that implement the 'TreeModel' interface:</span>
<a name="line-47"></a><span class='hs-comment'>-- the 'TreeStore' and the 'ListStore'. To use these, the developer simply</span>
<a name="line-48"></a><span class='hs-comment'>-- inserts data into these models as necessary. These models provide the data</span>
<a name="line-49"></a><span class='hs-comment'>-- structure as well as the 'TreeModel' interface. In fact, they implement</span>
<a name="line-50"></a><span class='hs-comment'>-- other interfaces, making drag and drop and storing data trivial.</span>
<a name="line-51"></a><span class='hs-comment'>--</span>
<a name="line-52"></a><span class='hs-comment'>-- A 'TreeModel' stores records of the same type. Each record is referred to</span>
<a name="line-53"></a><span class='hs-comment'>-- as row, just like in a relational database. Defining how the information of</span>
<a name="line-54"></a><span class='hs-comment'>-- a row is displayed can be done in two ways: If the widget displays data</span>
<a name="line-55"></a><span class='hs-comment'>-- using 'Graphics.UI.Gtk.ModelView.CellRenderer.CellRenderer' or one of its</span>
<a name="line-56"></a><span class='hs-comment'>-- derivatives, it is possible to state how a row is mapped to the attributes</span>
<a name="line-57"></a><span class='hs-comment'>-- of a renderer using the</span>
<a name="line-58"></a><span class='hs-comment'>-- 'Graphics.UI.Gtk.ModelView.CellLayout.cellLayoutSetAttributes' function.</span>
<a name="line-59"></a><span class='hs-comment'>-- Some widgets do not use</span>
<a name="line-60"></a><span class='hs-comment'>-- 'Graphics.UI.Gtk.ModelView.CellRenderer.CellRenderer's to display their</span>
<a name="line-61"></a><span class='hs-comment'>-- data. In this case an extraction function can be defined that maps a row to</span>
<a name="line-62"></a><span class='hs-comment'>-- one of a few basic types (like 'String's or 'Int's). This extraction</span>
<a name="line-63"></a><span class='hs-comment'>-- function is associated with a 'ColumnId' using</span>
<a name="line-64"></a><span class='hs-comment'>-- 'Graphics.UI.Gtk.ModelView.CustomStore.treeModelSetColumn'. The latter can</span>
<a name="line-65"></a><span class='hs-comment'>-- be set in the widget for the property that should be set. The widget then</span>
<a name="line-66"></a><span class='hs-comment'>-- uses the function 'treeModelGetValue' and the 'ColumnId' to extract the</span>
<a name="line-67"></a><span class='hs-comment'>-- value from the model. As the name suggests, using 'ColumnId's creates a</span>
<a name="line-68"></a><span class='hs-comment'>-- view of the data as if each row were divided into a well-defined set of</span>
<a name="line-69"></a><span class='hs-comment'>-- columns, again, like a relational database.</span>
<a name="line-70"></a><span class='hs-comment'>--</span>
<a name="line-71"></a><span class='hs-comment'>-- Models are accessed on a node level of granularity. There are two index</span>
<a name="line-72"></a><span class='hs-comment'>-- types used to reference a particular node in a model. They are the</span>
<a name="line-73"></a><span class='hs-comment'>-- 'TreePath' and the 'TreeIter'. Most of the interface consists of operations</span>
<a name="line-74"></a><span class='hs-comment'>-- on a 'TreeIter'.</span>
<a name="line-75"></a><span class='hs-comment'>--</span>
<a name="line-76"></a><span class='hs-comment'>-- A path is essentially a potential node. It is a location on a model that</span>
<a name="line-77"></a><span class='hs-comment'>-- may or may not actually correspond to a node on a specific model. A</span>
<a name="line-78"></a><span class='hs-comment'>-- 'TreePath' is in fact a synonym for a list of 'Int's and hence are easy to</span>
<a name="line-79"></a><span class='hs-comment'>-- manipulate. Each number refers to the offset at that level. Thus, the path</span>
<a name="line-80"></a><span class='hs-comment'>-- @[0]@ refers to the root node and the path @[2,4]@ refers to the fifth</span>
<a name="line-81"></a><span class='hs-comment'>-- child of the third node.</span>
<a name="line-82"></a><span class='hs-comment'>--</span>
<a name="line-83"></a><span class='hs-comment'>-- By contrast, a 'TreeIter' is a reference to a specific node on a specific</span>
<a name="line-84"></a><span class='hs-comment'>-- model. It is an abstract data type filled in by the model. One can convert</span>
<a name="line-85"></a><span class='hs-comment'>-- a path to an iterator by calling 'treeModelGetIter'. These iterators are</span>
<a name="line-86"></a><span class='hs-comment'>-- the primary way of accessing a model and are similar to the iterators used</span>
<a name="line-87"></a><span class='hs-comment'>-- by 'TextBuffer'. The model interface defines a set of operations using them</span>
<a name="line-88"></a><span class='hs-comment'>-- for navigating the model. Iterators are expected to always be valid for as</span>
<a name="line-89"></a><span class='hs-comment'>-- long as the model is unchanged (and doesn't emit a signal).</span>
