示例1: constructRelativeWheelEvent
static PlatformWheelEvent constructRelativeWheelEvent(const PlatformWheelEvent& e,
FramelessScrollView* parent,
FramelessScrollView* child)
{
IntPoint pos = parent->convertSelfToChild(child, e.pos());
// FIXME: This is a horrible hack since PlatformWheelEvent has no setters for x/y.
PlatformWheelEvent relativeEvent = e;
IntPoint& relativePos = const_cast<IntPoint&>(relativeEvent.pos());
relativePos.setX(pos.x());
relativePos.setY(pos.y());
return relativeEvent;

// It will be treated like a line scroll of 1 right now.
