So I tried this, and unfortunately it doesn't work. As you see, in the
WebTouchAction.h, in order to include "platform/graphics/TouchAction.h", I have
to use the "if BLINK_IMPLEMENTATION" thing. With that, compiler complains that
"no type named 'WebTouchAction' in namespace 'blink'" at this point. I am not
sure if there is a workaround on this.

 
   // Request the browser to show virtual keyboard for current input type.
   virtual void ShowVirtualKeyboardOnElementFocus() {}
