No need include this, because it's used only to implement the
PaymentRequestDialog's interface.

Done.

Can these two be made private? Then in the .cc file you would write something
like:

class PaymentRequestDilaogView::CardUnmaskUIDelegate {
 public:
  CardUnmaskUIDelegate() {}
  ~CardUnmaskUIDelegate() {}
  /// etc ...
};

I'm not sure what you mean. I'm just forward declaring them because they're used
as pointers in function parameters below.

[please use gerrit instead, 2017/03/31 14:41:14]

CvcUnmaskUIDelegate is used only as a private variable and not used by anyone
else. Therefore, you can move this forward-declaration inside of the private:
section of PaymentRequestDialogView.

Thanks for the details, this comment is now obsolete.
