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.
Documentdocument ()
 Return the Document that this command will modify during redo and undo.
const Documentdocument () 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.
MainWindowmainWindow ()
 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)
