Where the method is called?

[SaurabhK, 2014/01/15 16:57:08]

It is called from GamepadProvider::SendPauseHint()

+    virtual void PauseHint(bool ispaused);

[xwang, 2014/01/16 02:36:42]

Well, it should be "virtual void PauseHint(bool ispaused) OVERRIDE;"

[SaurabhK, 2014/01/28 13:23:09]

Updated it in latest patchset.

+
+    virtual void GetGamepadData(blink::WebGamepads* pads,
+                            bool devices_changed_hint) OVERRIDE;
