    "description": "The Tree control lets a user view hierarchical data arranged as an expandable tree. Each item in a tree can be a leaf or a branch. A leaf item is an end point in the tree. A branch item can contain leaf or branch items, or it can be empty.  <p>By default, a leaf is represented by a text label next to a file icon. A branch is represented by a text label next to a folder icon, with a disclosure triangle that a user can open to expose children.</p>  <p>The Tree class uses an ITreeDataDescriptor or ITreeDataDescriptor2 object to parse and manipulate the data provider. The default tree data descriptor, an object of the DefaultDataDescriptor class, supports XML and Object classes; an Object class data provider must have all children in <code>children</code> fields. </p>  <p>The Tree control has the following default sizing characteristics:</p> <table class=&quot;innertable&quot;> <tr> <th>Characteristic</th> <th>Description</th> </tr> <tr> <td>Default size</td> <td>Wide enough to accommodate the icon, label, and expansion triangle, if any, of the widest node in the first 7 displayed (uncollapsed) rows, and seven rows high, where each row is 20 pixels in height.
