LinuxCNC-specific Widgets Do Not Appear In QtDesigner was created by WireWall
Hello,
OS: 64bit Linux Mint 19.3
I am having trouble locating LinuxCNC-specific widgets and the widgets rules editor.
I followed the Installation process on the qtpyvcp website, including the development part.
Everything seems to be in order: QtDesigner works fine, LinuxCNC launches with the gui's made in QtDesigner.
However, there are no LinuxCNC widgets in the 'Widget Box' pane in QtDesigner.
So, how do I access these widgets?

Did you install the development stuff from the tutorial?

I followed the instructions from this page: www.qtpyvcp.com/install/installation.htm...all-dev-dependencies
It was not clear to me whether each sub heading was a separate option for a development install (pretty new to linux). I ended up ignoring the 'Installing from Debian package' section, but I followed the rest of the instructions.
Of note: when running the code "sudo apt install qttools5.dev qttools5-dev-tools wheel", part of the response I get is this: "E: Unable to locate package wheel"

the wheel package is missing, there are two ways one ist you search for the python wheel package of your distribution and install it or use pip:
sudo pip install wheel
sudo pip install wheel

I followed your instructions and installed wheel. I then reinstalled qtpyvcp per the instructions on the website.
I then ran 'editvcp' on a gui I was working on. Still no LinuxCNC-related widgets.
However, I did notice this error message in the terminal:
Starting QtDesigner ...
qt5ct: using qt5ct plugin
qt5ct: D-Bus global menu: no
[qtpyvcp-designer.plugins][CRITICAL] Error initializing plugin: qtpyvcp.plugins.status:Status(*[], **OrderedDict([('cycle_time', 75), ('report_actual_pos', False), ('use_program_units', True), ('metric_format', u'%9.3f'), ('imperial_format', u'%8.4f')])) (__init__.py:56)

TypeError: __init__() got an unexpected keyword argument 'imperial_format'

I know that's a lot of data, but the problem seems related to plugins.
I will look into this.

New info:
In QtDesigner, I selected Help>>About Plugins. This opened a window that listed the plugins, both working and failed.
Under the Failed Plugins, I found this error report:
Cannot load library /usr/lib/x86_64-linux-gnu/qt5/plugins/designer/libpyqt5_py3.so: (libpython3.5m.so.1.0:cannot open shared object file: No such file or directory)
I followed the specified filepath and found that the file "libpyqt5_py3.so" did exist.
Then, I searched for "libpython3.5m.so.1.0". I didn't find any instance of it, but I did find
"libpython3.6.so" and "libpython3.6m.so" in the filepath: "/usr/lib/python3.6/config-3.6m-x86_64-linux-gnu"
So it looks like QtDesigner is looking for an outdated version of libpython. I will research this further.

Question:
Does LinuxCNC 2.9 work with QtPyvcp/QtDesigner? I just check my version. I thought I had 2.8 installed, but I have 2.9.

Did you find a solution to this? I'm having the exact same problem. I am running Mint 19.3 with 2.8..
Thanks
John
I followed the instruction in this InstallQtVCPQtDesignerPlugins.tar.gz. I am trying to find where I came across it.
Found it: It is the first attachment in this post. Thanks hottabich.

Well, I had the LinuxCNC-specific widgets for a day. After an update of LinuxCNC the widgets are gone again.
