QThread exec proplem to stop...

[wysota]

It will finish, but only if he calls quit() outside the thread ...

It probably won't emit finished() then.

Oh, BTW QThread::quit() is not virtual, neither is exit.

Every slot is "implicitely" virtual if redeclared in a subclass. That's a side effect of how signals and slot mechanism works.

So I'm not sure how correct it is to reimplement it. Anyway, if qt uses your class, it will call the base class version.

No, it'll call the "youngest" implementation that has been declared as a slot. Of course this only applies to a situation when the method is called as a result of signal emission and not directly.
