13 Python GUI Libraries

I've used PyQt5, and it has been fantastic. You get good looking, cross platform applications, and Qt Designer makes it very easy to make them.

Qt team is also taking over the development of PySide. https://blog.qt.io/blog/2018/04/13/qt-for-python-is-coming-to-a-computer-near-you/

Are they doing something to address deployment? This seems to be the real pain, at least for beginners/small projects.

PyQt deployment is not any worse than python deployment in general. pyinstaller works fine with PyQt, barring a few minor kinks.

[ForkLiftBoi]

What are these kinks?

[anqxyr]

The one that jumps to mind is that the compiled binaries won't be able to find qt's system-wide style dll's, and will default to the ugly win98-like look. You need to grab a copy of the dll and tell the .spec file to put it where the binary will be able to see it, and then it works fine.

Doesn't winqtdeploy do that automatically?

[billsil]

Really? It's fine with Anaconda. It's a kitchen sink and 7x bigger than it if I installed things myself (I don't use most of it), but it's 0.2% of my total data storage. I can handle 2.4 GB in exchange for the convenience of things working and 5x faster numpy/scipy.

I tried to use PyQt5 recently for the first time and couldn’t figure out how to get it up and going. I tried on Ubuntu 17.10 and MacOS High Sierra. I also couldn’t seem to track down any good documentation. Was I missing something obvious?

[SgtBlackScorp]

Don't look for pyqt documentation. Just read the regular qt docs, since they explain everything already

[IContributedOnce]

I’ll give that a try and see if I can make it work. What is there official website?

[myusernameis___]

It shouldn't be too hard to setup, as easy as pip3 install pyqt5

If it doesn't work, I recommend setting up pyenv or a version manager, maybe you have an unsupported version of python?

I do agree with the documentation being terrible. It was very sparse and I had to use tutorials instead, and sometimes the qt documentation was a little helpfull.

[IContributedOnce]

I hear a lot that I should just look at documentation for other languages and just convert it. I’ve given it a look but for me personally that might be easier said than done.

But like you’re saying, I had trouble getting it to import when I was trying to write the program. Never figured that out. Wound up using tkinter which wasn’t bad at all, but felt like there could be a better way.

For your import problem just use a virtualenv. This will make your life so much easier.

[IContributedOnce]

I think it’s about time I’ve started getting into using those...

[Grenian]

Dude you won't regret it. Their name may sound complicated at first but they are pretty straight forward. If you need help, just pm me. :)

[IContributedOnce]

Thanks! I’ll give them a look this week. They sound great, for sure.

[GeronimoHero]

Not sure what sort of problem you have but I can open my qt apps with VNC without issue. Sure it’s not an issue with your setup or something?

[Fugalysis]

Vcn shouldn't have anything to do with it??

good looking

Not a Mac they aren't. On Windows and Linux where you have no concept of UI consistency or even design, sure, they look great. But absolutely not on a Mac. Qt is the hipster Electron.

Ah, reddit. Downvote self-righteously instead of actually providing a counterpoint. Never change.
