title: simple way to change JavaFX treeview background and text color
body: <p>This seems like something crazy simple, I'm new with JavaFX, and I cannot change the background and text color of JavaFX TreeView (added inside of a GridPane). Ive initialized the treeview constructor with the root node of populated treeitem. </p>
  
  <p>in the .css:</p>
  
  <pre><code>.myTree {
     -fx-font: 12px Tahoma;
     -fx-stroke: #eeeeee;
     -fx-background-color: #0a0a0a;
     -fx-text-fill: #ffffff;
     }
  </code></pre>
  
  <p>and in the code</p>
  
  <pre><code> treeView.getStyleClass().add("myTree"); 
  </code></pre>
  
  <p>the font sets, but nothing else. I cant seem to find any example of anyone changing the background of treeview - lots of doing fancy changes on select and hover.
  Any ideas ? </p>
