Inheritance diagram for musx::dom::others::KeyAttributes:

Public Member Functions
	KeyAttributes (const DocumentWeakPtr &document, Cmper partId, ShareMode shareMode, Cmper cmper)
	Constructor function.
Public Member Functions inherited from musx::dom::OthersBase
	OthersBase (const OthersBase &)=default
	explicit default copy constructor
	OthersBase (OthersBase &&) noexcept=default
	explicit default move constructor
Cmper	getCmper () const
	Gets the cmper key value.
std::optional< Inci >	getInci () const
	Gets the optional array index (inci).
Cmper	getRequestedPartId () const
	If this instance was retrieved from an object pool, it contains the part ID that was used to retrieve it. If this value is different than getSourcePartId, then this instance is a copy of the pool instance.
Public Member Functions inherited from musx::dom::Base
virtual	~Base () noexcept(false)=default
	Virtual destructor for polymorphic behavior.
DocumentPtr	getDocument () const
	Gets a reference to the Document.
Cmper	getSourcePartId () const
	Gets the source partId for this instance. If an instance is fully shared with the score, the source is SCORE_PARTID. If an instance is partially shared or non shared, the source is the ID of the part that sourced it.
ShareMode	getShareMode () const
	Gets the sharing mode for this instance.
const SharedNodes &	getUnlinkedNodes () const
	Gets the unlinked nodes for this instance. (Only populated for ShareMode::Partial)
void	addUnlinkedNode (const std::string &nodeName)
	Adds a shared node for this instance.
virtual void	integrityCheck (const std::shared_ptr< Base > &ptrToThis)
	Allows a class to determine if it has been properly contructed by the factory and fix issues that it can, such as creating default instances of contained classes.
virtual bool	requireAllFields () const
	Specifies if the parser should alert (print or throw) when an unknown xml tag is found for this class.

Static Public Member Functions
static const xml::XmlElementArray< KeyAttributes > &	xmlMappingArray ()
	Required for musx::factory::FieldPopulator.

Public Attributes
int	harmRefer {}
int	middleCKey {}
	MIDI key number to use for middle C. This value transposes playback if it is set other than the MIDI middle C value of 60.
Cmper	fontSym {}
int	gotoKey {}
Cmper	symbolList {}
	Cmper of the symbol list that specifies the accidentals for the key. These are stored in incidents of details::KeySymbolListElement.
bool	hasClefOctv {}
	If true, the key signature has clef octave override tables. See details::ClefOctaveFlats and details::ClefOctaveSharps.

Static Public Attributes
static constexpr std::string_view	XmlNodeName = "keysAttrib"
	The XML node name for this type.

Additional Inherited Members
Public Types inherited from musx::dom::Base
enum class	ShareMode { All , Partial , None }
	Describes how this instance is shared between part and score. More...
using	SharedNodes = std::set< std::string >
	The container type for shared nodes.
Protected Member Functions inherited from musx::dom::OthersBase
	OthersBase (const DocumentWeakPtr &document, Cmper partId, ShareMode shareMode, Cmper cmper, std::optional< Inci > inci=std::nullopt)
	Constructs an OthersBase object.
OthersBase &	operator= (const OthersBase &other)
	Assignment operator delegates to base, preserving OthersBase state.
OthersBase &	operator= (OthersBase &&other) noexcept
	Assignment operator delegates to base, preserving OthersBase state.
Protected Member Functions inherited from musx::dom::Base
	Base (const DocumentWeakPtr &document, Cmper partId, ShareMode shareMode)
	Constructs the base class.
	Base (const Base &)=default
	explicit default copy constructor

	explicit default move constructor
Base &	operator= (const Base &)
	no-op copy assignment operator allows subclasses to copy their values.
Base &	operator= (Base &&) noexcept
	no-op move assignment operator allows subclasses to move their values.

Detailed Description

Represents the attributes associated with a Finale key signature.

This class is identified by the XML node name "keysAttrib". The cmper is the key signature ID.

Member Data Documentation

fontSym

Cmper musx::dom::others::KeyAttributes::fontSym {}

If non-zero, the Font symbol ID used for accidentals in this key. Only the font ID can be specified. The size and style are inherited from the settings in options::FontOptions::FontType::Key.

gotoKey

int musx::dom::others::KeyAttributes::gotoKey {}

According to the Finale manual, this specifies the number of "scale steps" between each key on the MIDI keyboard. Presumably this means EDO division steps, but in any case it is not well implemented and seems not to work as intended. A value other than 1 is unlikely.

harmRefer

int musx::dom::others::KeyAttributes::harmRefer {}

Changes the meaning of 0 in the note tables for key signatures. The Finale manual recommends never changing it from 0. It also appears not to work as documented if changed. It was part of the original Finale 1.0 release and was likely never tested much since then.
