    I don't think this is actually anything to do with PyQt, or Qt. If you had copied and pasted the text instead of screenshot I could have quoted from it. But I see a Python3.8 json library loader complaining about some character in its JSON input.

    The error was, because part one of the files (the json), containing the xbee commands, has Russian in it, so the problem was with UTF-8 encoding, but i fix it.
    But now i have the following problem:

    File "C:/xbee-gui-master/MainForm.py", line 18, in <module>
        class Block(QtGui.QMainWindow, QtGui.QTreeView):
    NameError: name 'QtGui' is not defined
    

    How to solve it ?

      Qt5 moved widget code from QtGui to QtWidgets, change to that. You will have to do the same for any other widget stuff. I gave you reference to https://wiki.qt.io/Transition_from_Qt_4.x_to_Qt5 for this --- it's the very first item there --- and told you that's what I used to do the porting work.

          @Mitko said in PyQT4 App:

          QIcon

          This one is in gui module.
          I guess in PyQt it is PyQt5.QtGui

                  What is this?! You want to use QIcon, right?
                  It should be I guess

                  QtGui.QIcon("zigbee.png")
                  

                  It is also shown in the documentation which you should consult: https://doc.qt.io/qtforpython-5/PySide2/QtGui/QIcon.html

                              If you google for QVBoxLayout you will find https://doc.qt.io/qt-5/qvboxlayout.html and there it is clearly stated that it is in widgets module (qmake: QT += widgets).

                                    You should only get the same error if you left the code with QtGui.QVBoxLayout(self.centralWidget). After the import it should work with plain QVBoxLayout(self.centralWidget). Otherwise please don't say " same error" when so many errors are flying around, please show the actual line of any error and paste the error message.

                                        The first error is correct. from PyQt5 import QtWidgets, QtCore, QtGui is good. QVBoxLayout is not in PyQt5, so the error is correct.

                                        Your second example is correct. QtWidgets does contain QVBoxLayout so that is good.

                                        Given which, it is hardly surprising that

                                        self.centralWidgetLayout = QtGui.QVBoxLayout(self.centralWidget)
                                        

                                        gives the error it does, is it? You know that QVBoxLayout has been moved from QtGui in Qt 4 to QtWidgets in Qt 5, don't you, because that is what you are supposed to be changing to make it work. So there's no point putting what used to work and does not work now.

                                        Given your second example code, there are two ways you can address QVBoxLayout:

                                        • QtWidgets.QVBoxLayout: This is allowed from your from PyQt5 import QtWidgets line.

                                        • QVBoxLayout: This is allowed from your from PyQt5.QtWidgets import (QApplication, QWidget, QVBoxLayout, ... line.

                                          Hi, i'm really grateful for your help so far.

                                          I managed to clear that types of errors.

                                          But now i have different types of error:
