      @Deprecated
      public final class HorizontalSplitPanel
      extends SplitPanel

  A panel that arranges two widgets in a single horizontal row and allows the user to interactively change the proportion of the width dedicated to each of the two widgets. Widgets contained within a `HorizontalSplitPanel` will be automatically decorated with scrollbars when necessary.

  This widget will only work in quirks mode. If your application is in Standards Mode, use `SplitLayoutPanel` instead.
