@Mitko said in PyQT4 App:

PyQt5.QGui("zigbee.png")

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

You of course have to import this module like any other module

Via Interpreter ? I've try, it seems to installed, but i've got same error

@Mitko said in PyQT4 App:

Via Interpreter ?

Don't know what you mean.

from PyQt5 import QtGui

Mitko

@jsulm
Thank you, i fix this

But now i have this:

 Traceback (most recent call last):
  File "C:/xbee-gui-master/MainForm.py", line 360, in <module>
    main()
  File "C:/xbee-gui-master/MainForm.py", line 355, in main

    self.centralWidgetLayout = QtGui.QVBoxLayout(self.centralWidget)
AttributeError: module 'PyQt5.QtGui' has no attribute 'QVBoxLayout'

jsulm

@Mitko said in PyQT4 App:

QVBoxLayout

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).

Mitko

@jsulm
I'm new and don't understand everything

Mitko

@jsulm

I've try this but i have same error

from PyQt5.QtWidgets import (QApplication, QWidget, QVBoxLayout, QHBoxLayout,
                             QPushButton, QLabel, QLineEdit, QTabBar,
                             QFrame, QStackedLayout)

JonB

@Mitko
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.

@JonB

When i use:

from PyQt5 import QtWidgets, QtCore, QtGui, QVBoxLayout

I have this:

File "C:/xbee-gui-master/MainForm.py", line 3, in <module>
 from PyQt5 import QtWidgets, QtCore, QtGui, QVBoxLayout
ImportError: cannot import name 'QVBoxLayout' from 'PyQt5' (C:\xbee-gui-master\PyQT\lib\site-packages\PyQt5\__init__.py)

When i use:

from PyQt5 import QtWidgets, QtCore, QtGui

from PyQt5.QtWidgets import (QApplication, QWidget, QVBoxLayout, QHBoxLayout,
                             QPushButton, QLabel, QLineEdit, QTabBar,
                             QFrame, QStackedLayout)

I have this:

File "C:/xbee-gui-master/MainForm.py", line 35, in __init__
   self.centralWidgetLayout = QtGui.QVBoxLayout(self.centralWidget)
AttributeError: module 'PyQt5.QtGui' has no attribute 'QVBoxLayout'

JonB

@Mitko
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:

 C:\xbee-gui-master\PyQT\Scripts\python.exe C:/xbee-gui-master/MainForm.py
Traceback (most recent call last):
  File "C:/xbee-gui-master/MainForm.py", line 367, in <module>

    bl = Block()
  File "C:/xbee-gui-master/MainForm.py", line 50, in __init__
    self.all_tab()
  File "C:/xbee-gui-master/MainForm.py", line 63, in all_tab
    self.tab_control()
  File "C:/xbee-gui-master/MainForm.py", line 160, in tab_control
    self.list_all_commands()
  File "C:/xbee-gui-master/MainForm.py", line 211, in list_all_commands
    self.connect(self.view, QtCore.SIGNAL("clicked(const QModelIndex&)"), on_item_clicked)
AttributeError: 'Block' object has no attribute 'connect'

Can you please help me ?

SGaist

You wrote as if it was C++. That's wrong.

With PyQt/PySide:

source_object.name_of_signal.connect(target_object.name_of_slot)

Replace source_object and target_object with suitable objects in your code.

Note that in the project your linked to, there are several connect statements already done.

JonB

@Mitko

self.connect(self.view, QtCore.SIGNAL("clicked(const QModelIndex&)"), on_item_clicked)

That is the original.

I have never heard of self.connect().
I doubt that QtCore.SIGNAL("clicked(const QModelIndex&)") is acceptable, but I don't know.

I would try

self.view.clicked.connect(on_item_clicked)

Meanwhile separately I note that the code has:

class Block(QtGui.QMainWindow, QtGui.QTreeView):

That means Block is derived from two QObjects, QMainWindow & QTreeView. This is explicitly forbidden in Qt, at least in Qt5 and/or C++. Maybe it worked in Qt4/PyQt4, but will not now in any circumstances....

Meanwhile, I don't know why you couldn't find this for yourself but isn't https://github.com/RuslanSdk/XBee-PyQt5-V.1.0 like it says Qt5/PyQt5 and what you want?

Mitko

@JonB

I think i fix this:

self.view.clicked.connect(on_item_clicked)

About the "Block" error - is there some Qt5 replacement ?

About the project you refer to - i've tried it and it can be runned, but it can't load more then one xbee modules, and i wish to establish a network with meny devices.
I tried to contact the creator, but he don't reply.

Meanwhile i have new errors:

 C:\xbee-gui-master\PyQT\Scripts\python.exe C:/xbee-gui-master/MainForm.py
Traceback (most recent call last):
  File "C:/xbee-gui-master/MainForm.py", line 367, in <module>

  File "C:/xbee-gui-master/MainForm.py", line 174, in tab_control
    model = QtWidgets.QStringListModel()
AttributeError: module 'PyQt5.QtWidgets' has no attribute 'QStringListModel'

Any help, please ?

JonB

@Mitko
Now it's time for you to do the looking up. These questions are the same each time, and I don't see why I should look up the documentation for you.

The error tells you why you can't write QtWidgets.QStringListModel(). So you need to find whatever module QStringListModel() is in.

Mitko

@JonB
Since you saw that i'm now to this, can't you just say:

''QStringListModel is a QtCore class, not QtWidgets'' ?

Mitko

@JonB
Any way... I run it.

But when i try to make test, it can't obtain xbee modules, and when i hit the ''compound'' button, the app don't respond.
