File ui/views/controls/textfield/textfield_views_model.cc (right):

http://codereview.chromium.org/10412009/diff/2001/ui/views/controls/textfield...
ui/views/controls/textfield/textfield_views_model.cc:319: size_t new_cursor =
text.length();
Does this force scrolling when the omnibox does a SetText? Or is that handled
separately?

render_text_->SetCursorPosition(new_cursor) will take care of it.
(It treated as if a user moved the cursor to the end)
