// A class that handles managing the tab strip in a browser window. It uses
// a supporting C++ bridge object to register for notifications from the
// TabStripModel. The Obj-C part of this class handles drag and drop and all
// the other Cocoa-y aspects.
//
// When a new tab is created, it loads the contents, including
// toolbar, from a separate nib file and replaces the contentView of the
// window. As tabs are switched, the single child of the contentView is
// swapped around to hold the contents (toolbar and all) representing that tab.

  // maps TabContents to a TabContentsController (which owns the parent view
  // for the toolbar and associated tab contents)
  NSMutableDictionary* tabContentsToController_;

// Initialize the controller with a view and model. Both must be non-nil.
