Seems that we'll be reusing it later for OOBE/ScreenLock too.

Should it be |login_url| ?

[Ben Goodger (Google), 2011/05/18 16:50:51]

nit: move these public setters above the interfaces/overrides. Don't forget to
update the .cc to match order.

[rharrison, 2011/05/19 00:31:43]

Removed them since I don't actually use them.

[Nikita (slow), 2011/05/18 20:22:12]

Please move to the .cc file since it's a virtual function.
http://dev.chromium.org/developers/coding-style#TOC-Inline-functions

Same applies to the subsequent virtual functions with empty bodies.

[rharrison, 2011/05/19 00:31:43]

Done.

[Ben Goodger (Google), 2011/05/18 16:50:51]

Why would someone override these? (I see they're virtual). Can you add a
comment?

[rharrison, 2011/05/19 00:31:43]

We don't need to override them. That was an artifact of having cribbed this from
the TouchBrowserFrameView.

+  virtual void UpdateKeyboardAndLayout(bool should_show_keyboard);
+  virtual VirtualKeyboardType DecideKeyboardStateForView(views::View* view);

[oshima, 2011/05/18 18:24:54]

do we still need this?

[rharrison, 2011/05/19 00:31:43]

I do not know. I left it in since it was in the code that I was cribbing from
TouchBrowserFrameView. Should I contact sky about this?
