Detailed Description

This is the main class that the plugin should use as it exposes only the necessary methods of the param as well as redefine a couple of operators which helps in writing simpler and natural code (the param behaves like T in many ways).

Constructor & Destructor Documentation

GUIRawVstParam()

GUIRawVstParam ( std::shared_ptr< GUIRawVstParameter > iPtr = nullptr )

inline

Member Function Documentation

connect() [1/2]

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

inline

Returns

an object maintaining the connection between the parameter and the callback

connect() [2/2]

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

inline

Returns

an object maintaining the connection between the parameter and the listener

copyValueFrom()

tresult copyValueFrom ( GUIRawVstParam const & iParam )

inline

Shortcut to copy the value from another param to this one.

edit() [1/2]

Editor edit ( )

inline

Returns

an editor to modify the parameter (see Editor)

edit() [2/2]

Editor edit ( ParamValue const & iValue )

inline

Shortcut to create an editor and set the value to it.

Returns

an editor to modify the parameter (see Editor)

exists()

bool exists ( ) const

inline

getParamID()

ParamID getParamID ( ) const

inline

getStepCount()

int32 getStepCount ( ) const

inline

Returns

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

getValue()

ParamValue getValue ( ) const

inline

Returns

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

operator ParamValue()

operator ParamValue ( ) const

inline

Allow to use the param as the underlying ParamType (ex: "if(param)" in the case ParamType is bool)).

operator*()

ParamValue operator* ( ) const

inline

allow writing *param to access the underlying value (or in other words, *param is the same param.value())

operator=() [1/2]

GUIRawVstParam & operator= ( GUIRawVstParam const & iOther )

default

Assignment operator: fMyParam = registerParam(...);.

operator=() [2/2]

GUIRawVstParam & operator= ( ParamValue const & iValue )

inline

Allow to write param = 0.5.

resetToDefault()

tresult resetToDefault ( )

inline

Resets the param to its default value.

setValue()

tresult setValue ( ParamValue const & iValue )

inline

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

toString() [1/2]

Steinberg::String toString ( )

inline

Returns a string representation of this parameter.

toString() [2/2]

void toString ( String128 oString )

inline

Populates the oString with a string representation of this parameter.

toUTF8String()

std::string toUTF8String ( int32 iPrecision ) const

inline

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

update()

bool update ( ParamValue const & iValue )

inline

Update the parameter with a value.

Returns

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

value()

ParamValue value ( ) const

inline

Synonym to getValue().
