gtk-sharp Gtk# is thread aware, but not thread safe; See the Gtk# Thread Programming for details. GLib.Object System.Collections.IEnumerable

A store for that provides data from an arbitrary class. It is simpler to use than the .

This class provides a simple mechanism of implementing the Model required by the .


     [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);
         }

Iteration: In new versions of Gtk# (2.0 and up) this class implements the interface, so code can be written like this:


     void DumpColumnValues (NodeStore store, int col)
     {
         foreach (object[] row in store) 
              Console.WriteLine ("Value of column {0} is {1}", col, row [col]);
     }

Constructor a

NodeStore constructor

Creates a for nodes of the specified . The type provided in must implement . Method System.Void a

Appends the node to the root level of the tree

Adds to the end of the list of root level nodes. Method System.Void a the position to insert it at

Inserts the node into the root level of the tree

Adds to the list of root level nodes before the node currently at . Method System.Void

Removes all nodes from the store.

Method System.Collections.IEnumerator

Gets an enumerator for the root nodes.

a Children of root nodes are not enumerated. You must traverse them independently. Method Gtk.ITreeNode The path to look up.

Returns a node given a .

To be added. Looks up the node corresponding to and returns it, or null if the node cannot be found. Method System.Void a

Removes a node from the store.

Removes from the list of root level nodes.
