Constructor & Destructor Documentation

◆ ParameterChangeHandler()

tracktion::engine::ParameterChangeHandler::ParameterChangeHandler ( Edit & e )

Creates a ParameterChangeHandler for a given Edit.

Definition at line 14 of file tracktion_ParameterChangeHandler.cpp.

Member Function Documentation

◆ actionFunctionTriggered()

void tracktion::engine::ParameterChangeHandler::actionFunctionTriggered ( int externalControllerID )

Called by the accelerators when an assignable action is called.

This gets added to the pending list which CustomControllerSurfaces can check when controllers are moved and they are in MIDI learn mode.

Definition at line 62 of file tracktion_ParameterChangeHandler.cpp.

◆ getPendingActionFunctionId()

int tracktion::engine::ParameterChangeHandler::getPendingActionFunctionId ( bool consumeEvent )

noexcept

Returns the pending action function waiting to be assigned or a nullptr if none has been.

The object returned should be owned by the caller. Note that if consumeEvent is true this will consume the pending event so can't be reused for other controllers.
