Master PyQt5 part 11: Application Infrastructure and Communication

In this video, we'll talk about some basics of application infrastructure and inter-object communication for PyQt5 Applications.

Thanks for these videos. I watched them all. They really eased my learning of PyQt which is 90% of my work these days.

Alan, you are the only one on the internet who has tried to explain "program design". This was a great effort. I tried to write a real program. The program got so complex it just stopped working, I lost control of it. I still do not know how to design a large program. There is almost nothing on the internet about program design. I wish you would do more with program design. I tried to write a "flashcard" program. Thank You

[rkntan]

Well, the sibling analogy is helped me figure out something I have been struggling to solve. That's it. Thank you very much!

[dnmnsmith]

Just bought your book on the strength of the videos. Thank you!

[AlphaWatt]

Dude thank you for this. Lately Ive been trying to write using factories etc. but end up still tightly coupled in some ways. These examples and analogies really helped. Thanks again!

[andredempsey]

Great analogies. I’ve always avoided signals and slots because they seemed complicated and I never took the time to understand them. This video inspired me to start using them. Thanks!!

[ali-kadar]

Signals and slots and all the other object-oriented stuff may look overkill for toy applications but they are essential for building large scalable applications with loosely coupled components. That's a very important piece of advice. Thanks again. I think I am going to go grab that book of yours to learn in more depth.

Still learning and was heading down the wrong path on an app I am working on. Reconfigured my GUI as suggeted and it now makes it way more clearer. Thx

[mimmotronics]

Thank you so much for making these. For me, this was easily the most important video in the playlist, as it addressed problems I was having when using Tkinter before embarking on learning Qt.

[vicktorus]

That's analogy about your children is very special ! This never happen here ! ;) :) :) ;)

[manonthedollar]

18:00 Man, this is such good advice. This whole video came along exactly when I needed it. Thank you!!

[Vogelmama]

Hey Alan,
Thank you very much for your lessons! I've seen it twice
It was a pleasure listing your voice, experience & deep knowledge ❤️

[Darth_Pro_x]

Love all the analogies! great guide :)

[Dimlutube]

Another great video. Glad I watched the whole series. You made some complicated things very easy to understand.

[Factory]

After going through your book and other videos - this is exactly where I got stumped.
So glad you were able to make this video.

your content and delivery is perfect for my learnign style. Please continue! My goal is to become a python programmer
(my previous career path was been derailed due to 2020)

[greggrivas]

What an informative video, thank you for your hard work sir. I have a question though. What happens when one has multiple ui files (from qt designer for example) and wants to bind all that together? (let's say for example I have one ui file for the main window you are using here and then a different ui file for the settings window you are using here)

[normreed]

Thanks, I got your book and it is good but this video tied it up for me

[rebelScience]

Hey Alan, thank you for your work. I am wondering if there is a "Second Edition" of your book planed? Or if there is a place where one could get the latest version of it (if it is at all applicable).

[richiericher]

So basically, we we are mimicking LabView-style programming but with actual code

Great explanation though
