Rather than do this in Widget, can you just move this code into the window.cc
file in src/chrome/browser... since you only use this in one place.

Done.

+  Widget::InitParams params(views::Widget::InitParams::TYPE_WINDOW_FRAMELESS);
+  params.delegate = delegate;
+  // Will this function be called if !defined(USE_AURA)?
+#if defined(OS_WIN) || defined(USE_AURA)
+  params.parent = parent;
+#endif
+  params.bounds = bounds;
+  widget->Init(params);
+  widget->SetContentsView(delegate->GetContentsView());

I was thinking for moving SetContentsView(delegate->GetContentsView()) and
SetInitialBoundsForFramelessWindow into Widget::Init() for else part of if
(RequiresNonClientView(params.type)), but I found some existing codes are
calling widget->SetContentsView(xx) after widget->Init(), although most time
delegate and the parameter passing to SetContentsView are the same, but I am a
little concerned if we can assume that all the time, therefore, I left this
outside Widget::Init(), the code maybe cleaner the other way. Any suggestion?
