title: Creating own component based on TreeView (TTreeNode issue)
body: <p>just need o access to my custom TreeView with this:</p>
  
  <pre><code>MyTreeView1.Selected.MyOwnProperty := 'something';
  </code></pre>
  
  <p>So, all i want to do is make same component as TreeView is but + i need to add my own property to all of the TreeNodes of TreeView.</p>
  
  <p>If I may ask again, can anybody explain me how to use "data property of TTreeNodes to point to an object"? Could anybody explain how to save some information to it (for example name and age) and how to get this information from selected TTreeNode?</p>
