Additional Inherited Members
Protected Member Functions inherited from CmdAbstract
void	baseAttributes (QXmlStreamWriter &writer) const
	After writing leaf class attributes, this writes the base class atributes.
Document &	document ()
	Return the Document that this command will modify during redo and undo.
const Document &	document () const
	Return a const copy of the Document for non redo/undo interaction.
void	leafAttributes (const QXmlStreamAttributes &attributes, const QStringList &requiredAttributesLeaf, QXmlStreamReader &reader)
	Same as often-used leafAndBaseAttributes, except this is used in the special case where a class inherits from another class (e.g.
void	leafAndBaseAttributes (const QXmlStreamAttributes &attributes, const QStringList &requiredAttributesLeaf, QXmlStreamReader &reader)
	Before reading leaf class attributes, check all required attributes from leaf and this base class are included, then extract the parent class attributes.
MainWindow &	mainWindow ()
	Return the MainWindow so it can be updated by this command as a last step.
void	resetSelection (const PointIdentifiers &pointIdentifiersToSelect)
	Call this (for consistency) after writing leaf class attributes, to write the base class attributes.
void	restoreState ()
	Before any other operations associated with a Cmd class are performed, this method is called to restore original states to all relevant state machines.
void	saveOrCheckPostCommandDocumentStateHash (const Document &document)
	Save, when called the first time, a hash value representing the state of the Document.
void	saveOrCheckPreCommandDocumentStateHash (const Document &document)
	Save, when called the first time, a hash value representing the state of the Document.
void	selectAddedPointForMoving (const QString &pointAdded)
	Select point that was just added so it can be moved by the user next for convenience.
void	selectAddedPointsForMoving (const QStringList &pointsAdded)
	Select points that were just added so they can be moved by the user next for convenience.
