示例1: pointerMediaFeatureEval
static bool pointerMediaFeatureEval(const MediaQueryExpValue& value, MediaFeaturePrefix, const MediaValues& mediaValues)
{
MediaValues::PointerDeviceType pointer = mediaValues.pointer();
// If we're on a port that hasn't explicitly opted into providing pointer device information
// (or otherwise can't be confident in the pointer hardware available), then behave exactly
// as if this feature feature isn't supported.
if (pointer == MediaValues::UnknownPointer)
return false;
if (!value.isValid())
return pointer != MediaValues::NoPointer;
if (!value.isID)
return false;
