Member Function Documentation

◆ accessValue()

tresult accessValue ( typename ITGUIParameter< T >::ValueAccessor const & iGetter ) const

inlineoverride

◆ asDiscreteParameter()

std::shared_ptr<GUIDiscreteParameter> asDiscreteParameter ( int32 iStepCount )

inlineoverridevirtual

Converts this parameter into a discrete parameter.

The discrete parameter returned is a parameter with an underlying backing type int32 and values in the discrete range [0, getStepCount()] or [0, iStepCount] if getStepCount() <= 0.

Parameters

iStepCount if this parameter already defines a step count (getStepCount() > 0), then this parameter is ignored, otherwise it is used to convert this parameter into a discrete parameter with iStepCount steps.

Returns: the discrete parameter or nullptr if this parameter cannot be converted to a discrete parameter.

Implements IGUIParameter.

◆ connect() [1/2]

std::unique_ptr<FObjectCx> connect ( Parameters::IChangeListener * iChangeListener ) const

inlineoverridevirtual

Returns: an object maintaining the connection between the parameter and the listener

Implements IGUIParameter.

◆ connect() [2/2]

std::unique_ptr<FObjectCx> connect ( Parameters::ChangeCallback iChangeCallback ) const

inlineoverridevirtual

Returns: an object maintaining the connection between the parameter and the callback

Implements IGUIParameter.

◆ edit()

std::unique_ptr<EditorType> edit ( )

inlineoverridevirtual

Returns: an editor to modify the parameter (see Editor)

Implements ITGUIParameter< T >.

◆ getNormalizedValue()

ParamValue getNormalizedValue ( ) const

inline

Returns: the current value of the parameter as a normalized value

◆ getParamID()

ParamID getParamID ( ) const

inlineoverridevirtual

Each parameter has a unique ID returned by this method.

Note: Some parameters (in particular GUIOptionalParam) may return pongasoft::VST::UNDEFINED_PARAM_ID

Implements IGUIParameter.

◆ getStepCount()

int32 getStepCount ( ) const

inlineoverridevirtual

Returns: number of steps (for discrete param) or 0 for continuous

Implements IGUIParameter.

◆ getValue()

ParamType getValue ( ) const

inline

Returns: the current value of the parameter as a T (using the Denormalizer)

◆ setNormalizedValue()

tresult setNormalizedValue ( ParamValue const & iNormalizedValue )

inline

Sets the value of this parameter as a normalized value.

Note that this is "transactional" and if you want to make further changes that spans multiple calls (ex: onMouseDown / onMouseMoved / onMouseUp) you should use an editor

◆ setValue()

tresult setValue ( ParamType const & iValue )

inlineoverridevirtual

Sets the value of this parameter.

Note that this is "transactional" and if you want to make further changes that spans multiple calls (ex: onMouseDown / onMouseMoved / onMouseUp) you should use an editor

Implements ITGUIParameter< T >.

◆ toString() [1/2]

void toString ( String128 oString )

inline

Populates the oString with a string representation of this parameter.

◆ toString() [2/2]

String toString ( )

inline

Returns a string representation of this parameter.

◆ toUTF8String()

std::string toUTF8String ( int32 iPrecision ) const

inlineoverridevirtual

Returns the current value of the parameter as a string (which is properly UTF-8 encoded).

Parameters

iPrecision if iPrecision < 0 the parameter is free to use whichever precision is tied to the parameter otherwise it should use the one provided

Implements IGUIParameter.

◆ update()

bool update ( ParamType const & iValue )

inlineoverridevirtual

Update the parameter with a value.

Returns: true if the value was actually updated, false if it is the same

Implements ITGUIParameter< T >.
