 * when a study language is selected or deselected.
 * This class is used by StudyLanguageItem.
 * I was forced to do that because QCheckListItem doesn't
 * inherit from QObject and cannot emit signals.
 * and also because it's not possible to refer to PreferencesDialog from
 * QCheckListItem because of C++ mutual reference problem.
