Hi all,
I am fairly new to QT, but posting here because threading is not typically a n00b question.
I've read all the QT4 docs, tutorials, and examples on the new threading classes.
What I need is to simply run a function or class in a thread, and I'd really like to use
signals and slots to get some results back from the class.
I initially tried to use QtConcurrent and QRunnable, but neither one would compile
if I used Q_OBJECT in the class definition. After investigating the QT Object model
and such, it appears that neither will work, due to those classes needing a copy constructor
when invoking the thread.
Am I correct in this, or is there a special class construction that will let me use signals and slots with QtConcurrent or QRunnable?
Is it correct that I am limited to QThread if I want to use signals and slots?
NB: I'd really, really like to use QThreadPool, but it only supports QRunnable - dang.:crying:
