QTcpSocket, execution halts why and what does it mean?
-
@KroMignon , the examples I've found on QThread do not include how to NOT block the event loop, so an example on what to do in the thread so it doesn't block the event loop.
I've just added:
QCoreApplication::processEvents();To the thread loops, is this enough?

Here, this wont block:

This guy (https://stackoverflow.com/questions/37167927/proper-way-to-run-managable-background-thread-with-qthread) has made a similar mistake.
You want to connect once and then let the event loop and your signals do the rest. -

@Christian-Ehrlicher , is it any surprise I'm confused, in that thread you pointed me to the Fortune client and server examples, which I have been following then there is conflicting advice that comes back form this forum when I implement a solution that I'm having problems with.
Add to this the what appears to be flaky Qt Creator with updates that seem to send me backwards. I feel I'm loosing the plot.

The old thread told you to use signals and slots and not the waitFor functions and now we're at the exactly same place.

@Christian-Ehrlicher , well obviously I have mental memory issues.

@Christian-Ehrlicher , the examples that ship with Qt 5.15.2 include:
blockingfortuneclient
threadedfortuneserverOn looking at both, these are the sources I used to base my work on. My server is slightly different in that the clients are intended to stay connected after establishing a connection.
I will compare the client source with my own.

From my pov you don't need threads at all but this is not what you want to hear for whatever reason - you rather work on simple stuff like a QTcpSocket for months.

@Christian-Ehrlicher , one day I will be ready to share what I'm working on, which isn't now.

This sentence sounds strange to me.
I think you misunderstanding some comments/replies you received here.
My personal goal is to help other developers to solve problem they have will creating software with Qt, like I received help from other to solve/understand errors in my software.On the other side, this also helps me to get a better overview of Qt Framework and continue to learn.

@KroMignon , sorry, some of the comments, not yours I find a little offensive.
