So, I\'m trying to make a UI for a python code I have, but keep stumbling up on problems...
Right now, all the code does is make a window, with 2 texteditor boxes, a
Your error is from here:
Ui_Widget(QtGui.QWidget)
It basically tells you what the problem is.
It seems you are mixing some QT4 and QT5 here as your import is in QT5-style, but QtGui.QWidget looks like QT4-style.
Replace the line with:
Ui_Widget(QtWidgets.QWidget)
which should be compatible according to the docs
Remark: I don't know what you are really doing, but when you mention this: Even when I change class Ui_Widget(QtGui.QWidget): to class Ui_Widget(QtGui.QtWidgets): I get AttributeError: module 'PyQt5.QtGui' has no attribute 'QtWidgets'
That's correct. You already imported QtWidgets, and not from PyQt5.QtGui. Just use Ui_Widget(QtWidgets) there.
In short: all these errors seem to be related to refactoring in regards to the modules between QT4 and QT5. The docs should help.
