[constexpr] template <typename T> const T &qBound(const T &min, const T &val, const T &max)
返回以min 和max 为界的val 。这等同于qMax(min,qMin(val,max)) 。
举例说明：
int myValue = 10; int minValue = 2; int maxValue = 6; int boundedValue = qBound(minValue, myValue, maxValue); // boundedValue == 6
[constexpr] template <typename T> const T &qMax(const T &a, const T &b)
返回a 和b 的最大值。
示例：
int myValue = 6; int yourValue = 4; int maxValue = qMax(myValue, yourValue); // maxValue == myValue
[constexpr] template <typename T> const T &qMin(const T &a, const T &b)
返回a 和b 的最小值。
示例：
int myValue = 6; int yourValue = 4; int minValue = qMin(myValue, yourValue); // minValue == yourValue
