title: How to visualize UNLIMITED number of rows of data in TreeTableView in JavaFX?
body: <p>It is <a href="http://download.java.net/jdk8/jfxdocs/javafx/scene/control/TreeTableView.html" rel="nofollow">said in documentation</a>, that</p>
  
  <blockquote>
    <p>TreeTableView control is designed to visualize an unlimited number of
    rows of data</p>
  </blockquote>
  
  <p>Unfortunately, I can't see any means for this in the doc. </p>
  
  <p>All elements are stored in <a href="http://download.java.net/jdk8/jfxdocs/javafx/scene/control/TreeItem.html" rel="nofollow"><code>TreeItem&lt;&gt;</code></a> classes and stored in memory. Although, one can implement "unlimitness" with <code>ObservableList&lt;&gt;</code> I see no way to implement this on nested observable lists.</p>
  
  <p>"Unlimitness" require loading data by-demand, not storing it in memory.</p>
  
  <p>So is it finally possible to display data on demand in TreeTableView?</p>
