title: NSOutlineView - how to get horizontal scrollbar
body: <p>I'm trying to create a simple folder browser showing the tree structure using NSOutlineView. Using monoMac and Xamarin Studio with XCode interface builder for the UI.</p>
  
  <p>The problem I have right now is how to have the column resize to the width of the content and / or how to trim the text shown in the column.</p>
  
  <p>The first setting I tried is enabling AutoresizesOutlineColumn.
  This does resize the column to some degree, but once it encounters a name with hyphens it only resizes to the first hyphen, and from there it seems like it doesn't resize any further.</p>
  
  <p>Next I tried to enable set the column to resize to "AutoResize with table" and the cell to "truncate head", but this too does not work as I expected.</p>
  
  <p>What I want is the column to always be full width of context and then have the view show a horizontal scrollbar.
  Any pointers how to configure this ?.
  I have searched online, but the examples I have found is mostly on how to use the data source, nothing on how to configure the view itself.</p>
  
  <p>The 2 screenshot shows the issue, as you can see, when resized the node name is clipped not truncated and no scrollbar is shown</p>
