Function Documentation

[constexpr] template <typename T> const T &qBound(const T &min, const T &val, const T &max)

Returns val bounded by min and max. This is equivalent to qMax(min, qMin(val, max)).

Example:

int myValue = 10;
int minValue = 2;
int maxValue = 6;

int boundedValue = qBound(minValue, myValue, maxValue);
// boundedValue == 6

See also qMin() and qMax().

[constexpr] template <typename T> const T &qMax(const T &a, const T &b)

Returns the maximum of a and b.

Example:

int myValue = 6;
int yourValue = 4;

int maxValue = qMax(myValue, yourValue);
// maxValue == myValue

See also qMin() and qBound().

[constexpr] template <typename T> const T &qMin(const T &a, const T &b)

Returns the minimum of a and b.

Example:

int myValue = 6;
int yourValue = 4;

int minValue = qMin(myValue, yourValue);
// minValue == yourValue

See also qMax() and qBound().
