PyQt5 Tutorial - How to Use Qt Designer

[@chriss3154]

Using python 3.9 I found the designer.exe in site-packages -> qt5_applications -> Qt -> bin👍

Using Python 3.10.4, I found that PyQt5-tools had an error when installing. PyQt5 was fine. Nothing seemed to resolve this until I removed Python and installed 3.9.10 which allowed me to install both PyQt5 and PyQt5-tools. The Designer and pyuic5 both worked perfectly. Great tutorial! Thank you Tim.

I'm facing the same issue with the same edition 3.10.4, downgrading to 3.9.10 thnx

[@cnfnbcn3227]

That's because PyQt works only with Python 3.9 and lower

[@crimsonjester777]

I've been searching for how to make my Designer work for a month: googling weird advices, reading overcomplicated articles, digging into documentation... And you has solved my problem in a half an hour. Thanks!!!

[@ashish2099]

Initially I couldn't find pyqt5-tools inside scripts. Using pycharm with virtual environment made using virtualenv, python version 3.10.5. pyqt5-tools didn't get installed in my system for some reason. So, "pip install PyQt5Designer" within the same working directory as my virtual environment worked for me. I can now use designer.exe. As always, I'm grateful to tim for his clear explainations and free tutorials. God bless you brother, keep up the good work. You're definitely making this world a better place.

[@dahaze2k]

Same issue here at working with virtual environment at Python3.8 Just install PyQt5Designer itsself!👍

Just open up your console and type in "designer" after the pip installs

[@thekillerbunny]

This helped me a lot to get started, however I learned later that this is not the best way to program a more complicated program, as each time you edit the GUI, you rebuild the code, and have to code everything again (or just copy and paste). I found much more efficient to create a main program that loads the .ui file that's generated. It means you can make any changes to the GUI in QTDesigner and your code will not be affected. I used the function loadUI for the uic package in PyQt5. Just in case anyone else gets stuck there! Thanks for the tutorial, it def helped me to get started!

For those who are experiencing this error: "'pyuic5' is not recognized as an internal or external command, operable program or batch file. " This is because your pyuic5.exe is not in PATH. Probably your pyhton script folder is not in PATH, even though you put the option "add to Path" when you were installing Python. This happened to me, my Python folders are scattered around and I don't even know why. There are two methods of resolving: 01 - (What I did) The folder he shows that has all the files that pip installed, I added to PATH. (So much so that when you install a new library, you will no longer see that warning suggesting to add it to the path as the entire folder is already there.) There are already tutorials on the internet, it's very simple 02 - Instead of typing "pyuic5", you write the location where "pyuic5.exe" is. It's more complicated, but it also works. Like if I helped you :)

[@alessandrorotondo1906]

For those who cannot still solve the problem, use: python -m PyQt5.uic.pyuic youruifile -o yourpyfile -x Thank me later :D

Just started a python project that needed a GUI - having never done this much in python (I've done the odd py project and used circuitpython a fair bit but not as complex as my current project) -- this video playlist has been a godsend! Thank you so much for this pyqt5 series playlist / tutorial :)

[@ronaldknerr9018]

Hey Tim. Great tutorials. I just wanted to share an update. For those looking for the Designer.exe file, mine was located in ...Lib/sitepackages/qt5_applications/Qt/bin

[@davidgrove1600]

I finally got QtDesigner installed on my Samsung Chromebook Plus v2. To start out with, I installed all of QtCreator and Qt5. I ended up with a /usr/bin/designer that didn't work. It wanted something and I couldn't figure out what I installed QtDesigner for Qt 4, and that one worked. I found out that /usr/bin/designer was a reference. I changed my .desktop file for the "Qt 4 Designer" (find | grep) to "Qt Designer" and changed its command to "designer -qt=5". This means that the Qt4 version exists, but for whatever reason the new one works because of that. Maybe this will help someone. PLEASE KEEP MAKING THESE VIDEOS! PyQt is terribly under-documented.

[@noobownerbob]

Another way of finding where Python is installed on Windows is just typing the command in CMD: "where python" and it will show the installed locations on your PC!

[@till-louiswinters3484]

When you have no idea where you can find your python folder, open cmd/terminal and write "where python". That will show you the install path on your computer.

[@SafikMaster]

For anyone getting this error when trying to open the deigner: "this application failed to start because no qt platform plugin could be initialized" I solved it by going into the plugins folder and copying a folder called "platforms", I then pasted the folder where the designer.exe is located.

[@freedempire]

thank you, really helpful. for those who have the same problem: copy the whole folder of 'plugins' under folder pyqt5_tools\Qt, then paste it to folder pyqt5_tools\Qt\bin, replace, done!

I recommend PySide (now 6, for Qt6), it is very alike PyQt, but more up to date, and based on LGPL license - you don't need to publish source for your commercial code... BTW, Qt Designer comes as part of PySide, with no additional library to install.

The easiest way to find it without hunting through directories is to copy the installation address when you install it on the command prompt. c:\users\username\appdata\local\programs\python\python38-32\lib and go from there. It's usually inn the bin folder under Qt
