函数文档
[constexpr] template <typename T> const T &qBound(const T &min, const T &val, const T &max)
返回由min 和max 界定的val 。
示例：
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 中的最大值。
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 中的较小值。
示例：
int myValue = 6;
int yourValue = 4;
int minValue = qMin(myValue, yourValue);
