Hi All,
Any body help me to implement multi threading .. I am not able to find any examples..
I am working on Automated Futures Trading System, i have a functions which reads a data from a particular file and send to my GUI. Consider I have data in many files, all files need to read parallely and send to GUI same time.
Pls give me suggestions..
Regards,
Mani
See %QTDIR%/examples/threads.
In the examples for each thread a class has been derived..
But I need to run multiple threads at a time (more than 10) in a single class, hence I cant create class for each thread.. But I going to perform a single function which has one parameter inside those threads.. so i need to run that function paralelly..
Without creating instances for that class where I have my functions, Can I implement multi threading..?
What prohibits you creating several instances of such class?Quote:

But if ever possible you should derive from QThread and create an instance for every thread you need - for sure makes your life much easier.

Thanks for all your suggestions..
Actually I have a requirement to do this with out creating instances.. But i think that is only the easier way...
Thanks,
Mani
Excuse me, but what do you intend to use instead? If you want to do it the object-oriented way, you have to use instances (i.e. objects).Quote:
