We don't have asset management/localization yet. Add a TODO here to make the
hardcoded string go away and associate with bug 375533. Here and elsewhere.

This code will go a away, so I don't think TODO is useful here.

When we need a string for real UI, the author should simply create grd file and
that'll address this issue.

-  label->set_background(
-      views::Background::CreateSolidBackground(SK_ColorWHITE));
+  label->set_background(views::Background::CreateSolidBackground(0xFFDDDDDD));

Create a constant for this color.

[oshima, 2014/05/22 21:23:05]

Done.

   test_app_widget->SetContentsView(label);
   test_app_widget->Show();
