Could you remove this.

[Yoyo Zhou, 2013/04/15 18:43:28]

Yes, although I would then have to rewrite Cocoa and GTK UI layouts. (It is
slightly cumbersome for me to test them at the moment, so they might not look
polished for multi-line messages. But that can be fixed later.)

You can just grab the first message from the vector and add a TODO to process
the rest.

+  // Returns the messages for the bubble view. If present, takes precedence
+  // over GetBubbleViewMessage. Only supported on Views.
+  // TODO(yoz): Add support for GTK and Cocoa.

   // Returns the accept button label for the bubble view.
   virtual string16 GetBubbleViewAcceptButtonLabel() = 0;
   // Returns the cancel button label for the bubble view. To hide the cancel
   // button return an empty string.
   virtual string16 GetBubbleViewCancelButtonLabel() = 0;
   // Called when the bubble view is closed. |browser| is the Browser that the
   // bubble view was shown on.
   void BubbleViewDidClose(Browser* browser);

   // Browser that the bubble view was shown on.
   virtual void OnBubbleViewDidClose(Browser* browser) = 0;
   // Called when the user clicks on the accept button. |browser| is the
   // Browser that the bubble view was shown on.
