Is this needed? It seems that you need the definition for requesting_frame_.

[Miguel Garcia, 2014/06/20 20:50:12]

Now that it's not a reference anymore I in fact don't need it.

+class NavigationDetails;
+class PermissionQueueController;
+
+namespace gcm {
+
+// Base class for permission infobars, it implements the default behaviour
+// so that the accept/deny buttons grant/deny the relevant permission.
+// A basic implementor only needs to implement the methods that
+// provide an incon and a message text to the infobar.
+class PermissionInfobarDelegate : public ConfirmInfoBarDelegate {
+ public:
+  virtual ~PermissionInfobarDelegate();
+
+ protected:
+  PermissionInfobarDelegate(PermissionQueueController* controller,
+                            const PermissionRequestID& id,
+                            GURL& requesting_frame);

Done.
