hide the cmd windows for convenient.
thanks

(or maybe cffi can do it instead?)

When using Designer with custom widget plugins you must specify PYQTDESIGNERPATH to help it find your plugins. A custom CLI could easily provide access to setting these as well as the option to load it from a .env. There might also be activation stuff to handle or somesuch... but hopefully not with a console_scripts.

There's no need for the Qt applications to get processed for each Python version so let's break that out. #58 kind of forces the issue.

Just upgraded to version pyqt5-tools-5.15.1.1.7.3
Now I can't start Designer and get this error message

I uninstalled, and reinstalled, still same error.

This is my first week with PyQT5 and I need the Designer. I understand that this "wheel" package will do the trick. How exactly does one install this package?

PyQt5 version: 5.13.0
pyqt5-tools version: 5.13.0.1.5

I put a linguist_zh_CN.qm to pyqt5_tools\Qt\bin\translations, but the translations doesn't work on linguist like the picutre below.

Looking forward to your reply, Thank you for your work!

Please make a version compatible for PyQt5 version 5.13 and later.

Dear Folks,

I am fairly inexperienced with Python. Please bear with me.

Environment: Windows OS, pip 19.1.1 from anaconda installation.

I am interested in learning how to develop GUI's in PyQT. An online video suggested the way to start was to download pyqt5-tools using pip. The errors I get are:

Any ideas to my issue? I do not have a proxy server. But I am behind firewalls. I can do apt-get installs just fine and use curl to get stuff without issue in general. But for some reason, I have issues with pypi.org website here and with other packages.

Kind regards,
Kris

Python: 3.7.2
pyqt5-tools: v5.13.0.1.5

When using v5.11.3.1.4 (and even in v5.12.1.1.5rc4) built exe's run fine when they are created using pyinstaller. However, after the latest version release, pyinstaller cannot seem to find the pyqt5.sip module. It seems to have something to do with the entrypoint changes to the build.py file in commit a23a364.

For now i can run the previous version, and i understand if you would rather not look into a fix since the issue is pyinstaller related and might not be a problem for other users. If there's any other testing i can do, let me know.

Hello everyone, the current name for this package is pyqt5-tools, on the other hand, it must be PyQt5-tools in order to maintain visual similarity
As you can see from pip list :
Package Version

.....
pip 18.1
....
PyQt5 5.11.3
PyQt5-sip 4.19.13
pyqt5-tools 5.11.3.1.4
.....

Hello,

Thank you for your pyqt5-tools !
I did not manage to make appear plugin examples in Qt Designer. I installed a clean python 3.6.4 , I made a pip3 install PyQt5==5.9 (to be at the same version as pyqt5-tools),and I made a pip install pyqt5-tools.I modified the examples/designer/plugins/plugins.py script to find the binary designer.
In help> plugin Information, i have an error message telling "Cannot load library ......\pyqt5-tools\plugins\designer\pyqt5.dll: the specified module could not be found". I'm sure that the file existe and that designer found it because when I remove it , in help> plugin Information, QtDesigner juste say "QtDesigner could'nt find any plugins". Did you manage to have plugins visible in Qt Designer?
I really need it.

Cheers,

Baptiste

Hi there,
I'm trying to open designer from :
C:\Users\MyUsername\AppData\Local\Programs\Python\Python38\Lib\site-packages\pyqt5_tools\Qt\bin\designer.exe
but I'm getting
missing vcruntime140_1.dll
PS:
Python 3.8.2
pyqt 5.15.0

thanks.

Where's the main code?

How to call qtvirtualkeyboard

Hi there,

Are you planning to distribute launchers for Qt Assistant and Qt Linguist as well as Qt Designer ?
(something like "pyqt5assistant.exe" and "pyqt5linguist.exe" in Python "Scripts" folder)

Thanks,
Pierre

Any reason why dev10 isn't at https://pypi.python.org/pypi/pyqt5-tools ?

Would it be also possible to get a Python-3.9 wheel for Windows 10 64 bit ?

If you need space on pypi, I would suggest that maybe old 32bit wheels may have to go

It was a little less than trivial for me to figure out how to launch the QT designer (the official distribution puts shortcuts everywhere).

FYI it's Lib\site-packages\pyqt5-tools\designer\designer.exe and it might be worth noting this on the long_description

I cannot install the pyqt5-tools via pip. I first tried normally, and then after reading your suggestion for the other person, I setup virtualenv, and had pyqt successfully install there (as opposed to where I already had it installed, so I know I set this up right) However, the pyqt-tools don't.
I am on Windows 10 if it helps.

@jnickscott, it's best to open your own ticket for your own issue.

I don't have access to Windows at the moment but it's something like theenv\lib\site-packages\pyqt5_tools. If nothing else you can search for designer.exe.

It is good to use virtualenv or venv to create an isolated environment for each project you work on to install your packages in.

Presently, pyqt5-tools has redundant files with https://pypi.python.org/pypi/PyQt5/ making the download much larger. Do I understand correctly that pyqt5-tools is specific to a particular version of PyQt5? If so, how about creating a variation of pyqt5-tools that is a merge of the two? This would eliminate redundant files. I am hoping the merged version would reduce the probability of bugs too. If the download size is small enough, I am also hoping it will be included with the WinPython distribution, which used to include Qt Designer with PyQt4.

Such as 5.11 something with <=3.5.3 and 3.6.0 (or whatever the exact case is). Maybe more?

Dear,
My pyqt5-tools is the latest version. When I try to use Qt Assistant, or check the manual of Qt Linguist, it raise an error like:"Unable to launch Qt Assistant (C:/ProgramData/Anaconda3/Lib/site-packages/pyqt5-tools/bin\assistant)"

The path separator between bin and assistant is backslash, does this lead to this error?

Thanks for attention to this matter.

Yep, ran into PyPI's 30GB project limit so only some of the v1.7.5 wheels (with the translations files in Linux) were successfully uploaded. I need to find time to go through my options and resolve this.

Is there a way to rotate an image in a workbook? I can adjust the width and height of it but no rotational attributes in the Image object. Thank you

Hi,
I tried the below commands and none of them seems to find/install the package.

I have tried to install pyqt5-tools in the command line using 'pip install pyqt5-tools' and in Pycharm. But the results are the same, they appeared an error occurring that 'UnicodeDecodeError: 'gbk' codec can't decode byte 0x80 in position 2597: illegal multibyte sequence'. Later I would show the whole command output information.

Hi,
I installed pyqt5 with CLI command "pip3 install pyqt5".
But when I install PyQt5-tools with the same way : pip3 install PyQt5-tools, it shows message below:

Could not find a version that satisfies the requirement PyQt5-tools (from versions: )
No matching distribution found for PyQt5-tools

I have read other issues, and I know maybe it is too big to put it on pypi.

Do anybody knows how to install PyQt5-tools on mac?
THX.

Should we use 3.7 instead ???

I'm trying to load a custom plugin into designer and pyqt5designer silently crashes when it tries to load it.

Python version: 3.6.5
pyqt5 version: 5.11.3
pyqt5_tools version: 5.11.3.1.4rc0

I also tried to run pyqt5designer --test-exception-dialog and that crashes silently as well.

When testing with pyqt5 version 5.11.2 it seems to work just fine.

I recently tried to install pyqt-tools on Windows with Python 3.7.0, and it said that no versions could be found.

  Could not find a version that satisfies the requirement pyqt5-tools (from versions: )

Can you please create new version for recent version (5.14.1) PyQt5 and py 3.8?

When AppVeyor does...

https://www.appveyor.com/docs/windows-images-software/#python

If they do and there's no activity feel free to bump me.

When you go to view phyton code

It does not work because

They look for a path C:\Users[username]\AppData\Roaming\Python\Python38\site-packages\pyqt5_tools\Qt\bin\bin\uic.exe
but the correct path is just one \bin
I created the directory and worked. But I don't know where in the source code file is this path to correct

Thank you for your work!

It seems that the directory structure isn't quite acceptable for Designer to find the uic executable.

Can you please create new version for recent version (5.12.1) PyQt5?
Your package requires PyQt5==5.11.3

• Base setup info (Windows 10 - Pro):
• Installed pyqt5 and pyqt5-tools via pip3 command - No errors/installed properly/
• PATH is setup properly for Python 3.7.4 and PyQt5 and PyQt5-Tools

  =============
  Steps to reproduce
  =============

1. Open PyQt5 Designer (via Python Script folder)
2. Create a 1 button form and save.
3. Go to "Form>>View Code" and the error listed below is shown.

You are using pip version 8.1.1, however version 19.1.1 is available.
You should consider upgrading via the 'pip install --upgrade pip' command.

When running from a virtualenv and specifying the paths for PQTDESIGNERPATH (either via .env or via the -p CLI option of pyqt5designer) Designer starts and works as expected (shows the widgets if they are installed or error dialogs if they are not). From a venv you instead get a silent exit and DebugView output per below.

Tested against:
