     27 // constructor creates a FindBarCocoaController, which in turn loads a
     28 // FindBarView from a nib file.  All of this is happening outside of
     29 // the main view hierarchy, so the static method also calls
     30 // BrowserWindowCocoa::AddFindBar() in order to add its FindBarView to
     31 // the cocoa views hierarchy.
     32 //
     33 // Memory ownership is relatively straightforward.  The FindBarBridge
     34 // object is owned by the Browser.  FindBarCocoaController is retained
     35 // by bother FindBarBridge and BrowserWindowController, since both use it.
