void layoutAboutToBeAdded(const QString &name)
Emitted when a layout is about to be added to the manager.
void layoutRenamed(QgsMasterLayoutInterface *layout, const QString &newName)
Emitted when a layout is renamed.
void layoutRemoved(const QString &name)
Emitted when a layout was removed from the manager.
void layoutAdded(const QString &name)
