PyQt doesn't understand &

@user4592357
Hmm, although I don't use them myself, I concur. My code is a little different:self.actionCases = QtWidgets.QAction("&Cases", self) ... self.toolbar = QToolBar() self.toolbar.addAction(self.actionCases)"&Cases"does not show theCunderlined."&&Cases"shows as&Cases, so it's doing some ampersand-parsing. I'm Linux. Maybe it's not supposed to do anything on Linux? What are you? I have to doubt whether this is a Python/PyQt issue...wrote on 21 Feb 2018, 12:19 last edited by@JonB

there's another weird error that bothers me. whenever i import a class, for example:
from PyQt5.QtCore import QObjecti get this error:
E0611:No name 'QObject' in module 'PyQt5.QtCore'same goes for all
Qtclasses. -
Then again: which version of PyQt5 and Qt 5 are you using ?
How did you installed them ? -

PyQt version: 5.7 Qt version: 5.7.1 SIP version: 4.18.1Firstly, you say you are Qt

Secondly, you used
pip3to install PyQt. I had nothing but grief withpip3, and never used it. If you are saying you did apip3 install pyqt5and ended up with PyQt version 4.x, clearly something did not work correctly... Is it possible you have an older PyQt 4 lying around on your machine?@SGaist

So you are saying you are using PyQt 4.19.7 against Qt 5.10.0?
Plus, you did an install ofpip3 install pyqt5and you got PyQt 4.19.7?If this really is the case, you should not be surprised that things don't work/appear right.

I don't know, 'coz like I said I never got on with pip3.TBH, if you're saying you code actually works, I'd be surprised if it could run against PyQt4 at all. I wonder where you think you have PyQt 4 from in the first place? In my actual code I use
from PyQt5.Qt import PYQT_VERSION_STRto get it, so you know what your code is actually using. Andfrom PyQt5.QtCore import QT_VERSION_STRfor Qt version. -

Not sure if this helps and it has nothing to do with the version of PyQt but in Windows you need to use the ALT key to bring up the underline letter used with the “&” symbol.
It’s referenced in this SO question and answer

Look, I really don't where you are. But If you usedpip3 install pyqt5and you got PyQt4 something is really wrong. And if it did get PyQt5 but somehow your code only finds PyQt4 you are equally in a mess. So you need to sort this out before you go any further.... -

He said he was using:
SIP version: 5.10
PyQt version: 4.19.7I think he just switched those two around and is confused. The most current version of SIP is 4.19.7 and the most current version of PyQt is 5.10. There never has been a version of PyQt4 with that version number nor has SIP gotten to that version number yet.

i know it's hard to guess but it's 'she' :)
btw this happens on my new laptop where i only installed qt 5.10.1 and then pyqt5.
but the same happened also on my former laptop where i had qt4 and installed pyqt5.i have no idea what's going on
anyways, i downloaded the sources and wannabuild. got the following:
$ python configure.py Error: Use the --qmake argument to explicitly specify a working Qt qmake.python.exe .\configure.py --qmake C:\Qt\Qt5.10.1\5.10.1\msvc2015_64\bin\qmake .exe Querying qmake about your Qt installation... Determining the details of your Qt installation... Error: Failed to determine the detail of your Qt installation. Try again using the --verbose flag to see more detail about the problem. -
What do you get if you make it verbose ?
By the way, you may avoid much of the hassle by using pip/pip3 do install PyQt5.

From the looks of it, you're doing that from a console that's not configured to use Visual Studio 2015. You should either call the vcvars script with the correct parameters or start the console through the Visual Studio start menu.

i opened vs native tools x64 cmd and run the install command - same output.i run
C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\Common7\Tools\vsdevcmd\ext\vsvars.batfrom vs tools->command prompt menu, then run the install command - same output.EDIT: i uninstalled current version and installed with
pip install PyQt5(and notpip3, as before) and got the lastest versions:Qt version: 5.10.0 SIP version: 4.19.7 PyQt version: 5.10but:
pylint errors about imports aren't gone
the letter isn't still underlined. it's how @KevinKSyd said - only shows on alt key press -
Pylint might not find everything and you may have to help it searching for your dependencies.
As for the underline, it’s a Windows behavior.

I thought "&" was not working in my PyQt Windows project menus, but it turned out that the underscore only appears when Alt is being pressed.
