So you are using PyQt5 ?

PythonQTMarlem

yes, that is right!
from PyQt5 import QtCore, QtWidgets, QtGui, QtPrintSupport
from PyQt5.QtWidgets import *
from PyQt5.QtCore import QSize, Qt
from PyQt5.QtGui import QFont, QFontDatabase, QTextCursor, QTextCharFormat, QTextDocument, QColor, QIcon
from PyQt5.QtPrintSupport import QPrintDialog, QPrinter

SGaist

So which version of PyQt5 ?

PythonQTMarlem

i don't understand the question.
Why there is different versions?

SGaist

PyQt5 is the name of the package. It has a version number. Qt also has a version number, you are using Qt 5.9.7. PyQt5's version number does not necessarily follow the one from Qt.

PythonQTMarlem

okay, how i can find out the version of PyQt5?

SGaist

With "conda list" for example.

PythonQTMarlem

okay.
pyqt 5.9.2 in Windows.
in MacOS it should be the same, cause between the installation anaconda in windows and MacOs, was just 4 weeks.

SGaist

It seems that there's something going on with macOS 10.15 and the menu bar. Other non Qt application also have issues with it.
