optional nit for one-liner:
  void set_can_accept_events(bool value) { can_accept_events_ = value; }

Done.

nit: order just after can_focus_; optionally init to true here?

[riajiang, 2016/07/13 00:01:46]

Moved to be after can_focus_. Since can_focus_ is also initialized in the ctor,
I think it would be more consistent to leave it there?

[msw, 2016/07/13 01:04:19]

Acknowledged.
