[vtkusers] Does QVTKWidget create new threads?

[Ashika Umanga Umagiliya]

Greeting all,

I was wondering whether QVTKWidget create new threads for VTK related
process?
Because when QVTKWidget is create in my application,it display an warning
saying:

"QObject: Cannot create children for a parent that is in a different thread.

(Parent is QObject(0x112f5e68), parent's thread is QThread(0xb438a0),

current thread is QThread(0x112fedc0)"


PS: this is related to my previous post

Thanks in advance,
umanga
