<summary>A store for <see cref="T:Gtk.TreeView" /> that provides data from an arbitrary class. It is simpler to use than the <see cref="T:Gtk.ListStore" />.</summary>
<remarks>
<para>
This class provides a simple mechanism of implementing the Model required by the <see cref="T:Gtk.TreeView" />.
</para>
<example>
<code lang="C#">
[TreeNode (ColumnCount=2)]
class DemoNode {
string name;
string email;
public DemoNode (string name, string email)
{
this.name = name;
this.email = email;
}
[TreeNodeValue (Column=0)]
public string Name {
get { return name; }
}
[TreeNodeValue (Column=1)]
public string EMail {
get { return email; }
}
}
class Demo {
NodeStore store;
void PopulateStore ()
{
NodeStore store = new NodeStore (typeof (DemoNode));
DemoNode my_node = new DemoNode ("Miguel de Icaza", "miguel@ximian.com");
store.AddNode (my_node);
}
</code>
</example>
<para>
Iteration: In new versions of Gtk# (2.0 and up) this class implements the <see cref="T:System.Collections.IEnumerable" /> interface, so code can be written like this:
</para>
<para>
<example>
<code lang="C#">
void DumpColumnValues (NodeStore store, int col)
{
foreach (object[] row in store)
Console.WriteLine ("Value of column {0} is {1}", col, row [col]);
}
</code>
</example>
