They should have named it QtPy.... Seriously

[@nmstoker]

Excellent video. Clearly explained, with genuinely helpful clarifications, you've obviously put thought into this rather than cribbing points. Now I'm keen to watch other of your videos too 👍

[@JulianDWise]

Great video, well presented and pretty much told me what I needed to know. I'll subscribe and watch more!

[@perlasaadeh3322]

what an instructive video! Keep up the good work

[@CodePhiles]

very informative as usual, thanks Hala

[@sameer1234ification]

Good video. I have quite knowledge and experience in pyqt & pyside on both Windows and MacOs and still found your presentation useful. Please keep up the good work!

[@geoafrikana]

Superb exposition. Thanks so much.

[@henryzhao857]

That is helpful. Thank you very much!

[@uudecode]

thank you for this information about licensing!

[@dcuccia]

Excellent intro, thank you!

[@MrEdinaldolaroque]

Thank you for this very clear and concise explanation.

[@pfsniperguy1456]

Thank you for this. Very good explanation!

[@abimbolaobadare6691]

Thanks for this.

[@DanielRamBeats]

Clearly explains the license issues that are often quite ambiguous, thank you!

[@thegreencat7515]

Great video

[@nde810]

Thank you 💕

[@svgcrtns444]

Thanks, keep going, 1M subscribers will come,

[@slartibartfast7999]

Quite good video, but in my opinion two very important questions should be considered, too: Which one has the larger user base? And how easy is it to contribute (e.g. bugs, code, documentation). Both affects how up-to-date each software stays when it is already released. While a big user base might faster stumble uppon bugs in the software, and maybe provide workarounds or solutions, a project that allows easy contribution might even have faster provisioning of bug fixes. From my daily use, I would always go with pyqt in early development. And then, if really needed switch to pyside for releasing.

[@dimnike4657]

very useful video. Nice backstory

[@sarthakchoudhary6236]

It's just awesome

[@cos4242]

Thanks for informative video. But I'd like to point that Qt is not just a framework for building GUIs. It's a framework that contains tools for building GUIs but also much more. You can write command line tools, daemons and embedded software with it also nicely. You could compare it to boost library which does lot of same but doesn't have a GUI module.

[@ZeroGamersX]

Hala, I love you!!!!! your videos are actually on point and exactly what I need everytime

[@AESMatias]

Ty so much

[@sparklee6994]

How to use Asyncio with pyside6? I have a GUI designed by pyside6 (and Qt), behind the GUI I have intensive serial communication done by Pyserial and asyncio....can I share the same event loop required by GUI and asyncio?

[@bader2111]

فنانة ✋

[@sunilpandya7242]

Hi, I am from India, I want to use Pyside6 for my Commercial Application software for Accounting. I will use Pyside6's Text Entry, Labels Etc. I will not change the code for this labels and text entry etc. I will use Ditto as available. Can i Use as LGPL? What will be my obligation? I do not want to show my code to end user

[@henning7378]

0:01 Hello Welcome Back :)

[@davethinkingsystems]

Love it, thanks. So the take home is develop in QT and then port to pyside if you ever want to sell it :-)

[@landrhykopp9836]

Your voice....you speak very fluently. Thanks for this video !

[@jakewynn]

Am I wrong for thinking that pyside is only commercial (paid) licensing

[@jwsincla99999]

I believe you must release the source only if you distribute the work.

[@ronnyabraham3727]

I was wondering - even if I want to distribute my software, since it is python scripts, how can I hide the code from users? Isn't python code always source code?

[@pixeled_violence]

you can create an exe from the script.

[@ronnyabraham3727]

@@pixeled_violence How?

[@iluvsyphonfilter]

​@@ronnyabraham3727 The pyinstaller library is very popular to packaging python files into an executable. I haven't tried it though.

[@_isDev]

@@pixeled_violence ok and we she said "share the code with the app user"... what does she mean? because If I give my client a .exe how this pearson is to have the code? I am new using PyQt5 and maybe this is an answer well discuss before

[@marwanomar3311]

​@@_isDevI think when you use a free pyqt then you gave to share the source code with the user, but if you buy a license from pyqt you can hide your code.

[@martinson1252]

4:50 How does it make sense, to release source code of the app for free and then sell it?

[@JohnDoe-kw2nl]

It does make sense in quite a few scenarios. For example, selling technical software in business to business sells. Another is embeded. Look at the about info on any modern LG TV. It's actually running quite a lot of open source software under the LGPL.

[@_isDev]

I don't understand something: What do you mean by give my code to my client? how people from PyQt5 knows I am going to sell a gui built using this framework? If I create a .exe to install the gui in the client's computer... I don't really understand

[@havingfunxd]

Technically they do not know that you've used their code. However, even if you package your Python code into an .exe or .dmg it is still possible to de-compile your binary and see what symbols (function, constants, shared libraries ...) were used in it. That's where it is possible to deduce whether you used PyQT or not and if it is determined that you did, you'll be in violation of their license and they'll be able to win in court against you. If that happens, you'll be liable for breach of license agreement and would have to pay them damages. All in all, if you are developing software as a business, the legal risk isn't worth it.

[@_isDev]

@@havingfunxd thanks! I now get it!

[@PogoDigitalism]

If youre going to sell your program, you probably dont want to create it in Python, its very easy to decompile and pirate.

[@grkb]

Qt is actually pronounced as "cute" according to Wikipedia.

[@vegaswould]

i prefer tkinter when possible. sometimes simple is better

[@RussellNelson]

4:40 "GPL License" is "General Public License License". Same for LGPL.

[@StarChild.no1]

If people are going to commit to anyone of these to options, note there is no substantive community for working with these two frameworks. And absolutely zero for working with the QML language. (Qt is not QML) You’ll pretty much have a pretty interface but connecting to a database or doing serial communications, you’ll be on your own. It should come with a warning, that the developers of the framework don’t respect the time commitment of folks new to the framework. But this would become obvious when you see that no one is really offering any tutorials on it. You can take your chances with Qt but not the QML part.

[@egedesolomon7454]

Which do you suggest that is amazingly similar and has a larger community support?

[@StarChild.no1]

@egedesolomon7454 So far, it's been my experience working with Pyside6 using QML as it pertains to community support, they're both the same thing. It's really the import statements are worded differently. And after spending time using QML, there has yet a problem or feature implementation that I haven't been able to solve, doing Google searches, StackOverflow or the Documentation.

[@michaelosajeh4111]

They're python libraries so can't you just leverage the existing python tools and community for those tasks?

[@StarChild.no1]

@michaelosajeh4111 Yes. That's what I did. I mostly utilized PySide signal slots and properties to connect to qml. But for tasks lilke serial communication, threading, and database stuff, I leaned on the Python community's robust support. A.I. (Codium) is also a good tool for offering up suggestions on the Pyside6 libraries, but it also struggles. But it rocks for pure python and cpp work. I use Qml because it gives me the opportunity to code in a Model, View, Controller, OOP style. Plus QML is really straightforward and tidy..

It’s not QuTee, it’s pronounced “Cute”.
