Dear all,

I would kite to know know can I notify errors from objects of classes derived from QObjects. Searching in the net, many times I've seen that if is suggested to overload the QCoreApplication::notify() member function (http://stackoverflow.com/questions/4...error-handling), but i don't like it much, I would prefer to notify errors by emiting signals. For example:

Qt Code: 
  1. class Foo : public QObject
  2. {
  3. Q_OBJECT
  4.  
  5. Q_SIGNALS:
  6. void error(QString string);
  7.  
  8. Q_SLOTS:
  9. void do_something()
  10. {
  11. try
  12. {
  13.   a = ...;
  14.   <do something>
  15. }
  16. catch (std::exception &e)
  17. {
  18.  Q_EMIt error(QString::fromStdString(e.what()));
  19. }
  20. }

Does anyone uses this policy? How do you use it? One signal per exception type? How do you notify errors from Qt objects?

Thanks and Best Regards,
