QtDesigner and PyQt5: The right and wrong way to use them together

Author Alan D Moore describes some common pitfalls of using QtDesigner with PyQt5, and the proper way to combine the two to build GUI applications.

Thanks for watching!

I found your video after doing 80% of the wrong steps you went over here. Thank you for explaining this so clearly. I'll be getting your book for sure.

2022 and still the best video here on youtube about this topic! Golden tips. There a lot of content about PyQt5, but they are not so usefull as this video, because it clears so much and explains how does it work.

Thought this was obvious enough, seems like it wasn't, thanks for doing this labor for all of those who didn't think they would loose their changes

You saved my life on my senior design project. Couldn't figure out why none of my buttons would connect and now it all makes sense!

[joegodby]

Excellent. One of only a few coders on YouTube that are well organized, stay focused and on track. Take some time and watch his Classes Playlist.

I have already made the mistake in making my application and already gone so deep in the development that I think it can't be undone. Will start from scatch again.

I feel very lucky that I stumbled across your channel.

Hi! Your channel saved me! I’ve been making this exact mistake in my project and suffering from all these errors and not understanding whats going on! found your video three days before deadline, I fixed everything thanks to you. I hope you’re safe and happy.

Extremely valuable advice, exactly what I was looking for! Thanks a lot!

I'm an artist and I always liked to learn programming languages... a few years ago I started learning Python by myself, searching tutorials here and there, when I knew about QT Designer I said to myself: "This is what I need, I'm an artist, I need visual design". Then, a few days later I understand is much more easy and fun (to me) code the full UI, it's make easy to me to add a "UI presets menu" to the app I was doing that let the user change the app apareance. Thanks for the video, is amazing

[slickwillie]

LOL I was doing exactly what you said (copying and pasting). What great advice. No surprise you wrote the book on it. Gotta get the book.

Excellent video, thank you! 30 minutes to remember everything I've forgotten over the last 4 years. 👍👍👍

Thank you for teaching the sanity, and correct "python" way.
I have been watching many vids and they either change the generated code which I know is wrong since all those changes would have to be done again, or the import the ui, which makes the app way slower at start up. I was struggling getting my mind wrapped around using these classes and you made it clear :-). Your book is now on it's way to my home.
Thank you again for the clarity.

Very useful. My past GUI apps have been browser based but I have to do one now with Qt. Tried out Designer and was undecided about it until I watched you video. Your last comments were spot on. Thanks!

[isidrodeleon]

Excellent video. I add that the UI compiler can be configured in the IDE (in my case I use PyCharm) as an "external tool", so that, after modifying and saving the .ui file with QtDesigner, it is no longer necessary to manually compile the file .ui (with just three clicks inside PyCharm, and the updated code appears).

I was 10 seconds away from doing everything the wrong way. Thank you for demonstrating this!

[ali-kadar]

That is a very good piece of advice for people who are beginning to build GUI's in Python using Qt. Thanks very much.

It was interesting watching this video, because I’m reading your book (well, re-reading. Qt is complicated). On your ending comments about coding directly instead of using Designer: I do know from your book how you quickly create some sets of widgets (some of it’s not really ‘manual’, wink-wink.). But also, I’ve created a few more involved GUIs, and I can appreciate making some big changes in Designer, then quickly back up in running editing the slots and other methods without having to worry about the GUI code. So I’ll probably keep doing it both ways.

Thanks for your book. Cheers. :-)

I have seen this video floating around for a couple of months, never watched because it was 37 minutes long, lazy I know but truth. I am so glad I finally watched it as it clarified so much to me. Thank you!

[narbus]

thank you very much, this video is extremely helpful, I'm here because an user from stackoverflow recommended me to watch your video.

[zskater]

I'm so glad that I've found this video. You're THE man!
