Creating UI's (Qt or not )
Adam Baker
I haven't seen much posted about building more complex UI's with Python. I've been trying to learn how build "changing" UI ( building UI's that can collapsing based on the users needs). In this research most of the document and tutorials point to me switching and used QT and QT designer instead of the build in Python syntax. If anyone can help me, either with pointing me in the right direction or letting me know if I should switch to using QT instead ( positives and negatives of using QT).

Adding to what Justin said, the primary benefit of using C++ for Qt is that you’re in the native language of Qt. There are things you can do in C++ that you can’t do as easily in Python, and some of the lower-level operations are more tricky in Python because of that. But that’s all on the technical side, not the UI functionality side. Also, if you’re not already comfortable developing in C/C++, it’s going to be a much steeper learning curve to go to that, especially from an interpreted language like Python. In short, if you prefer direct control and management of your memory (and are comfortable with the challenges that entails), C++ is the answer. If you prefer to leave that to the system and just want an amazing UI, one of the other options (like Python) is likely going to be your ticket.
When it comes down to it, it’s far more important to be proficient in the language you choose than to choose the right language. The Qt Framework as a whole provides the UI functionality, the language you use is just what will help you get there. Additionally, the actual decisions of what you’re doing with your program will tend to be far more important to this choice than the UI framework you use — decisions such as which libraries you want to use, how you want your program to run, memory persistence, etc.
As to the Qt Designer vs hand-coding debate, the only thing you really gain from hand-coding is knowledge of how everything works. Also, if something doesn’t work correctly, it’s more direct to identify the problem and fix it. Other than that, everything you do in Designer ends up compiled down to the same code at runtime, so you’re not limited in actual functionality because of that choice.

You can build complex behaviour either way.C++ may offer benefits over python in certain situations where performance becomes a concern.

If you enjoy python, and want the faster prototyping of an interpreted language, use Python.Justin

I've got a feeling the OP was interested in a comparison between Maya's UI framework, and Qt, rather than Qt with C++ versus Qt with Python. Not sure, need a bit more information.

So I guess I will learn to how to use QT designer/QT over the next few days. I see that you (Justin) have made a video tutorial on QT. Any other websites/Videos for good pyQt learning material(other then your video)?
Thank you all your help !

Not sure, need a bit more information.Hmm that is possible and would make sense for comparison.Adam, if that is true then there is definitely a difference between what you can do in Maya native elf UI and Qt. You only get the functionality that Maya exposes, which can be limited for complex UI. So yes, using Qt is the way to get 100% control over your design.

Yes sorry I should have been more clear with my post. Marcus is right I am talking about the Maya's UI framework and QT. Right now I have no plan to learn C++ nor do I currently have a vast knowledge on C++.
So I guess I will learn to how to use QT designer/QT over the next few days. I see that you (Justin) have made a video tutorial on QT. Any other websites/Videos for good pyQt learning material(other then your video)?
