TreeNode abstract class

Convenience class for deriving ITreeNode implementing objects for implementations. This class can be subclassed to quickly implement a node type without having to implement the tree building and navigational aspects of the interface. The following example shows a simple subclass:


[TreeNode(ColumnCount=1)]
public class MyTreeNode : TreeNode {
	string level;
    
	public MyTreeNode (string level)
	{
		this.level = level;
	}
    
	[TreeNodeValue(Column=0)]
	public string Level { 
		get { 
			return level; 
		} 
		set {
			level = value;
			OnChanged ();
		}
	}
}

The base class provides all the details and MyTreeNode uses to notify of tree related node changes. System.Object Gtk.ITreeNode System.Reflection.DefaultMemberAttribute Method System.Int32

IndexOf method

a a Returns the child index of or -1 if is not a child of this . Method System.Void

OnChanged method

Raises the Changed event. Call this method if any column values of the node change. Constructor

TreeNode constructor

a Default constructor.. Property System.Int32

ID property

ChildCount

a Read-only. The number of children of this node. Property Gtk.ITreeNode

Child indexer

Changed event

Raised when the contents of the change. Use for a convenient way to raise the event. Event Gtk.TreeNodeAddedHandler

ChildAdded event

ChildRemoved event

Raised when a child is removed from the node. Property Gtk.ITreeNode

Parent property

a Read-only. The parent for this node. Method System.Void

AddChild method

a Adds the specified to this . The is added to the end of the children list, the property of is set to this node, and the event is raised. Method System.Void
