Constructor & Destructor Documentation

◆ Ratio() [1/3]

constexpr Ratio ( )

inlineconstexprnoexcept

Default Constructor.

Here is the caller graph for this function:

◆ Ratio() [2/3]

constexpr Ratio ( const Ratio & ratio )

inlineconstexprnoexcept

Copy Constructor.

Parameters

ratio Another Ratio object

◆ Ratio() [3/3]

constexpr Ratio ( qint32 ppm )

inlineexplicitconstexprnoexcept

Constructor with a ratio in PPM.

Parameters

ppm	The ratio in PPM

◆ ~Ratio()

~Ratio ( )

default

Destructor.

Member Function Documentation

◆ setRatioPpm()

void setRatioPpm ( qint32 ppm )

inlinenoexcept

Set the ratio in PPM.

Parameters

ppm	The ratio in PPM

◆ setRatioPercent() [1/2]

void setRatioPercent ( int percent )

inlinenoexcept

Set the ratio in percent.

Parameters

percent The ratio in percent

Here is the caller graph for this function:

◆ setRatioPercent() [2/2]

void setRatioPercent ( qreal percent )

inlinenoexcept

Set the ratio in percent.

Parameters

percent The ratio in percent

Warning: To set an exact value, please use the overload setRatioPercent(int) instead.

◆ setRatioNormalized() [1/2]

void setRatioNormalized ( qreal normalized )

inlinenoexcept

Set the ratio as a normalized number.

Parameters

normalized The normalized ratio

Warning: If you want to set the ratio exactly to common values like 0%, 50% or 100%, you should not use this method. Please use setRatioPercent(int) or setRatioPpm() instead because it is more accurate (no use of floating point numbers). Or you can also use the static method setRatioPercent(int).

Here is the caller graph for this function:

◆ setRatioNormalized() [2/2]

void setRatioNormalized ( const QString & normalized )

inline

Set the ratio as a normalized number, represented in a QString.

This method is useful to read ratios from files (deserialization).

Parameters

normalized See fromNormalized(const QString&)

Exceptions

Exception If the argument is invalid, an Exception will be thrown

Here is the call graph for this function:

◆ fromNormalized() [1/2]

Ratio fromNormalized ( qreal normalized )

staticnoexcept

Get a Ratio object with a specific ratio.

Parameters

normalized See setRatioNormalized(qreal)

Returns: A new Ratio object with the specified ratio

Here is the call graph for this function:

Here is the caller graph for this function:

◆ fromNormalized() [2/2]

Ratio fromNormalized ( const QString & normalized )

static

Get a Ratio object with a specific ratio.

This method can be used to create a Ratio object from a QString which contains a normalized floating point number, like QString("0.1234") for 12.34 percent. The string must not depend on the locale settings (see QLocale), it have always to represent a number in the "C" locale. The maximum count of decimals after the decimal point is 6, because the 6th decimal represents one ppm.

Parameters

normalized See setRatioNormalized(const QString&)

Returns: A new Ratio object with the specified ratio
