I doubt many people will be willing to answer your repeated questions on this 
topic because you have been told many times that you

***should not perform GUI operations from a worker thread***. 

Yet you continue to ignore the advice and guidance given to you.

As some relevant advice, if you have that many items you should consider using 
the model/view architecture.

If you insist on using an item based approach then break your creation up into 
smaller chunks and *do it in the main thread*. If you call qApp-
>processEvents() at regular intervals it will keep your GUI responsive.

And finally please try reading the documentation on threading and look at the 
examples.
