[James Cook, 2013/10/02 21:07:55]

Just to double-check, are we sure we want to hide the close button? Is there a
design doc on window controls I can look at?

[pkotwicz, 2013/10/03 20:45:35]

I think that we are sure that we want to hide the close button

+// them when the user hovers at the top edge of the screen. (crbug.com/297181).
+class ASH_EXPORT HideableCaptionButtonContainer : public views::WidgetObserver {

[pkotwicz, 2013/10/02 19:41:49]

Do you have a suggestion for a better class name? (I realize the name is not
very correct because the controls are not hideable yet, but I am planning on
changing that very shortly and I want to avoid needless code churn)
I thought of HideableCaptionButtonContainerController but it is too long.
I would rather not use HideableCaptionButtonWidget given that the class adds a
views::WidgetObserver on |frame_|, not |button_widget_|.

[James Cook, 2013/10/02 21:07:55]

HideableCaptionButtonController?  Or just keep it the way it is.

[pkotwicz, 2013/10/03 20:45:35]

HideableCaptionButtonContainer it is then.

+ public:
+  static const char kButtonWindowName[]; // visible for test
+
+  // |background_id| is the idr of the image to use as the background.

[James Cook, 2013/10/02 21:07:55]

idr -> "resource id" or "IDR resource id"

[pkotwicz, 2013/10/03 20:45:35]

Done.
