I don't think this is used.

[thanhph1, 2017/01/17 20:19:05]

Done.

You have no #include that contains mojom::DisplayModeProxyDataView or for the
gfx::Size StructTrait definition.

[thanhph1, 2017/01/17 20:19:05]

Done.

+namespace mojo {
+
+template <>
+struct StructTraits<ui::mojom::DisplayModeProxyDataView,
+                    ui::DisplayMode_Params> {
+  static const gfx::Size& size(const ui::DisplayMode_Params& d) {

[kylechar, 2017/01/17 17:19:26]

I would call the parameter |mode| or |display_mode| for clarity, here and in the
two methods below.

[thanhph1, 2017/01/17 20:19:05]

Done.

+    return d.size;
+  }

[kylechar, 2017/01/17 17:19:26]

Whitespace between methods.

[thanhph1, 2017/01/17 20:19:05]

Done.

+  static bool is_interlaced(const ui::DisplayMode_Params& d) {
+    return d.is_interlaced;
+  }

[kylechar, 2017/01/17 17:19:27]

You shouldn't need this check.

[thanhph1, 2017/01/17 20:19:05]

Done.
