Aug 05, 2017 PyQt5 Fifth Lesson, Signal And Slots Structuring our Window In A Class. Sep 10, 2019 You will get a much quicker response if you include a completely functional bit of code that allows one to copy/paste and run it to see what you are doing. Also are you using just QT or PyQt and/or are you using some kind of Designer the latter btw while based on Qt/PyQt does not actually produce Qt/PyQt code. New-style Signal and Slot Support¶ This section describes the new style of connecting signals and slots introduced in PyQt4 v4.5. One of the key features of Qt is its use of signals and slots to communicate between objects. Their use encourages the development of reusable components. Connections may be made across threads. Signals may be. Passing extra arguments to PyQt slots April 25, 2011 at 13:38 Tags Python, Qt. A frequent question coming up when programming with PyQt is how to pass extra arguments to slots. After all, the signal-slot connection mechanism only specifies how to connect a signal to a slot - the signal's arguments are passed to the slot, but no additional (user.
I have a program which interfaces with a radio I am using via a gui I wrote in PyQt. Obviously one of the main functions of the radio is to transmit data, but to do this continuously, I have to loop the writes, which causes the gui to hang. Since I have never dealt with threading, I tried to get rid of these hangs using
QCoreApplication.processEvents().
The radio needs to sleep between transmissions, though, so the gui still hangs based on how long these sleeps last.Is there a simple way to fix this using QThread? I have looked for tutorials on how to implement multithreading with PyQt, but most of them deal with setting up servers and are much more advanced than I need them to be. I honestly don't even really need my thread to update anything while it is running, I just need to start it, have it transmit in the background, and stop it.

I created a little example that shows 3 different and simple ways of dealing with threads. I hope it will help you find the right approach to your problem.
