Member Function Documentation

virtual tresult setComponentState ( IBStream *  state )

pure virtual

Receives the component state.

Implemented in EditController.

virtual tresult setState ( IBStream *  state )

pure virtual

Sets the controller state.

Implemented in EditController.

virtual tresult getState ( IBStream *  state )

pure virtual

Gets the controller state.

Implemented in EditController.

virtual int32 getParameterCount ( )

pure virtual

Returns the number of parameters exported.

Implemented in EditController.

virtual tresult getParameterInfo ( int32  paramIndex, ParameterInfo &  info  )

pure virtual

Gets for a given index the parameter information.

Implemented in EditController.

virtual tresult getParamStringByValue ( ParamID  id, ParamValue  valueNormalized, String128  string  )

pure virtual

Gets for a given paramID and normalized value its associated string representation.

Implemented in EditController.

virtual tresult getParamValueByString ( ParamID  id, TChar *  string, ParamValue &  valueNormalized  )

pure virtual

Gets for a given paramID and string its normalized value.

Implemented in EditController.

virtual ParamValue normalizedParamToPlain ( ParamID  id, ParamValue  valueNormalized  )

pure virtual

Returns for a given paramID and a normalized value its plain representation (for example -6 for -6dB - see vst3AutomationIntro).

Implemented in EditController.

virtual ParamValue plainParamToNormalized ( ParamID  id, ParamValue  plainValue  )

pure virtual

Returns for a given paramID and a plain value its normalized value.

(see vst3AutomationIntro)

Implemented in EditController.

virtual ParamValue getParamNormalized ( ParamID  id )

pure virtual

Returns the normalized value of the parameter associated to the paramID.

Implemented in EditController.

virtual tresult setParamNormalized ( ParamID  id, ParamValue  value  )

pure virtual

Sets the normalized value to the parameter associated to the paramID.

The controller must never pass this value-change back to the host via the IComponentHandler. It should update the according GUI element(s) only!

Implemented in EditController.

virtual tresult setComponentHandler ( IComponentHandler *  handler )

pure virtual

Gets from host a handler which allows the Plugin-in to communicate with the host.

Note: This is mandatory if the host is using the IEditController!

Implemented in EditController.

virtual IPlugView* createView ( FIDString  name )

pure virtual

Creates the editor view of the plug-in, currently only "editor" is supported, see ViewType.

The life time of the editor view will never exceed the life time of this controller instance.

Implemented in EditController.
