There is an inner class in called GridSplitBar. I want to style this bar differently than the default GXT styles, but it has no unique stylename assigned to it. Furthermore the instance variable ("bar") is private, so I can't even override this by extending the class.

I'm proposing that a styleName be attached to the GridSplitBar, OR that the private member variable in GridView called "bar" be promoted to a protected member variable. Either would allow user's to better extend the visualization of the grid.
