In Qt 5.0 - Qt Introduced the QException class.
What is benifit of inheriting from this class? What if we throw a class that does not inherit from the QException class?
Thank you in advance!

3From the [documentation](http://qt-project.org/doc/qt-5/qexception.html) (emphasis mine): `The QException class provides a base class` **`for exceptions that can [be] transferred across threads`**. – Frédéric Hamidi Apr 18 '14 at 09:50

@Laszlo I am not satisfied that much... though i have voted your comment as useful.. – DesignIsLife Apr 21 '14 at 05:48

Why are you not explaining what is missing rather than obsoleting the thread? – László Papp May 15 '14 at 08:35

In short, you can find the answers by reading the relatively short documentation.
Q: What is benefit of inheriting from this class?
This is the corresponding part of the documentation:
The QException class provides a base class for exceptions that can transferred across threads.
In addition to that, it integrates pretty well with the QtConcurrent feature set, including QFuture.
Q: What if we throw a class that does not inherit from the QException class?
This is the corresponding part of the documentation:
If you throw an exception that is not a subclass of QException, the Qt functions will throw a QUnhandledException in the receiver thread.

I have already had gone through this documentation part... but Some things are still unclear.. as - What if Qt functions will throw a QUnhandledException in the receiver thread ?? - Is this class is Useful to only when threading i.e. `QtConcurrent` or `QFuture` will come in picture..?? - I can Make own Class and throw that, in General case will it make difference ? – DesignIsLife Apr 18 '14 at 11:50

@DesigningLives: Hmm, based on your questions, the basics are not in place. Please start the reading in here: http://qt-project.org/doc/qt-5/qtconcurrent-index.html – László Papp Apr 18 '14 at 11:56
