Two windows in the same main

[wysota]

For testing asynchronous communication you don't need threads.

[nkint]

thank you for the answer.

so the way i'm handling it now (two window.show in the same main) is a right way?
is there a better way?

[wysota]

It's ok but don't create two instances of QApplication. One is enough. Your current code would not even compile

[nkint]

Ah yeah sorry I have done some cut and paste for deleting comments and renaming the objects and there was a mistake.. : )

So it is ok, I can test how many TCP package can be sent for a second and stuffs like this, good, thank you!

One more question:
what happens if I use moveToThread methods on a QWidget subclass?

[wysota]

Most likely - BOOM!
Less likely, a warning and a no-op.

[nkint]

sorry?

boom could mean runtime crash but.. no-op?

anyway thank you for the answer i have understand i don't have to do it.

[anda_skoa]

Yes, boom refers to crashing
no-op is short for "no operation", a term using in computer science to say that an instruction will actually not do anything.
Like an empty method
