Constructor & Destructor Documentation

◆ AudioParameterFloat() [1/2]

juce::AudioParameterFloat::AudioParameterFloat ( const String parameterID,
const String name,
NormalisableRange< float >  normalisableRange,
float  defaultValue,
const String label = String(),
Category  category = AudioProcessorParameter::genericParameter 
)

Creates a AudioParameterFloat with an ID, name, and range.

On creation, its value is set to the default value.

◆ AudioParameterFloat() [2/2]

juce::AudioParameterFloat::AudioParameterFloat ( String  parameterID,
String  name,
float  minValue,
float  maxValue,
float  defaultValue 
)

Creates a AudioParameterFloat with an ID, name, and range.

On creation, its value is set to the default value. For control over skew factors, you can use the other constructor and provide a NormalisableRange.

◆ ~AudioParameterFloat()

juce::AudioParameterFloat::~AudioParameterFloat ( )

Destructor.

Member Function Documentation

◆ get()

float juce::AudioParameterFloat::get ( ) const
noexcept

Returns the parameter's current value.

◆ operator float()

juce::AudioParameterFloat::operator float ( ) const
noexcept

Returns the parameter's current value.

◆ operator=()

AudioParameterFloat& juce::AudioParameterFloat::operator= ( float  newValue)

Changes the parameter's current value.

◆ valueChanged()

virtual void juce::AudioParameterFloat::valueChanged ( float  newValue)
protectedvirtual

Override this method if you are interested in receiving callbacks when the parameter value changes.

Member Data Documentation

◆ range

NormalisableRange<float> juce::AudioParameterFloat::range

Provides access to the parameter's range.
