    I stated that the example I quoted seems already to be in PyQt5. I have no idea what it does, as I don't speak Russian.

    The github code you quoted is in PyQt4. Personally I would rather update that to PyQt5 than try to install and get PyQt4 working. Up to you.

    Ok, if i can't use PyQt4, how can i convert this part of the project (that use PyQt4 ) to PyQt5 ?
    The project should establish zigbee topology, but i can't test it

      I don't know if you mean by "part of the project" that you think you can have a project containing some PyQt5/Qt5 stuff and some PyQt4/Qt4 together in one app. If you do think that, you can't. So you have a couple of choices:

      • Continue your original route of trying to get PyQt4/Qt4 installed and running, using the various resources you were trying for PyQt4/Qt4, so that you can use xbee-gui as-is. I just think that's rather hard, and not good going forward if you intend to do further development, but I never did that so I don't know.

      • Change xbee-gui code to move to PyQt5/Qt5. I used https://wiki.qt.io/Transition_from_Qt_4.x_to_Qt5 and perhpas https://stackoverflow.com/questions/46554746/pyqt4-to-pyqt5-how for that.

      • Find some already-ported version of xbee-gui or ask the original developer. But I don't know that you will get much joy that way.

      As you please.

          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

                                      Please do also some research on your own!
                                      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).
