    • setDelegateRenderer

      public void setDelegateRenderer(TreeCellRenderer delegate)
      Sets the delegate. If the delegate is null, the default is created via the tree's factory method. Updates the folder/leaf icons. THINK: how to update? always override with this.icons, only if renderer's icons are null, update this icons if they are not, update all if only one is != null.... ??
      Parameters:
      delegate - the delegate to use, if null the list's default is created and used.
