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