Member Function Documentation

willUpdateMusicalContextProperties()

virtual void ARAMusicalContextListener::willUpdateMusicalContextProperties ( ARAMusicalContext * musicalContext, ARA::PlugIn::PropertiesPtr< ARA::ARAMusicalContextProperties > newProperties )

virtual

Called before the musical context's properties are updated.

Parameters

musicalContext	The musical context whose properties will be updated.
newProperties	The musical context properties that will be assigned to musicalContext.

didUpdateMusicalContextProperties()

virtual void ARAMusicalContextListener::didUpdateMusicalContextProperties ( ARAMusicalContext * musicalContext )

virtual

Called after the musical context's properties are updated by the host.

Parameters

musicalContext

The musical context whose properties were updated.

doUpdateMusicalContextContent()

virtual void ARAMusicalContextListener::doUpdateMusicalContextContent ( ARAMusicalContext * musicalContext, ARAContentUpdateScopes scopeFlags )

virtual

Called when the musical context's content (i.e tempo entries or chords) changes.

Parameters

musicalContext	The musical context with updated content.
scopeFlags	The scope of the content update indicating what has changed.

didAddRegionSequenceToMusicalContext()

virtual void ARAMusicalContextListener::didAddRegionSequenceToMusicalContext ( ARAMusicalContext * musicalContext, ARARegionSequence * regionSequence )

virtual

Called after a region sequence is added to the musical context.

Parameters

musicalContext	The musical context that regionSequence was added to.
regionSequence	The region sequence that was added to musicalContext.

willRemoveRegionSequenceFromMusicalContext()

virtual void ARAMusicalContextListener::willRemoveRegionSequenceFromMusicalContext ( ARAMusicalContext * musicalContext, ARARegionSequence * regionSequence )

virtual

Called before a region sequence is removed from the musical context.

Parameters

musicalContext	The musical context that regionSequence will be removed from.
regionSequence	The region sequence that will be removed from musicalContext.

didReorderRegionSequencesInMusicalContext()

virtual void ARAMusicalContextListener::didReorderRegionSequencesInMusicalContext ( ARAMusicalContext * musicalContext )

virtual

Called after the region sequences are reordered in an ARA MusicalContext.

Region sequences are sorted by their order index - this callback signals a change in this ordering within the musical context.

Parameters

musicalContext

The musical context with reordered region sequences.

willDestroyMusicalContext()

virtual void ARAMusicalContextListener::willDestroyMusicalContext ( ARAMusicalContext * musicalContext )

virtual

Called before the musical context is destroyed.

Parameters

musicalContext

The musical context that will be destroyed.
