PyQt5 - Button clicked.connect() - No suggestions

Question

I create applications using **QtDesigner **by loading .ui files.

Everything works but why there are no suggestions when writing code for clicked.connect(some_def) e.g.:

I have python 3.11.3 and PyCharm IDE installed.

code example:

`from PyQt5 import QtWidgets, uic from PyQt5.QtWidgets import QMainWindow, QAbstractButton import sys

class Ui(QMainWindow): def init(self): super(Ui, self).init() uic.loadUi('gui.ui', self)

    #self.button = QtWidgets.QPushButton("&Print", self)
    self.button = self.findChild(QtWidgets.QPushButton, 'printButton')
    self.button.clicked.connect(self.printButtonPressed)
    self.show()

def printButtonPressed(self):
    print('printButtonPressed')

app = QtWidgets.QApplication(sys.argv) window = Ui() app.exec_()`

I tested on python 3.10.11 and python 3.8.10 but the suggestions still don't work.

It seems pretty obvious that pycharm wouldn't be able to recognise objects defined in a ui file (which is xml) that is loaded as runtime. If you want auto-completion, you can use [pyuic](https://www.riverbankcomputing.com/static/Docs/PyQt5/designer.html#pyuic5) to create static python modules instead. — ekhumoro, Apr 17 '23 at 21:11
Hi So I have to convert ".ui" to ".py", load the MainWindow class and it should work. I will check. — Kacper10714, Apr 18 '23 at 15:40

Not sure but it could be because of the flag on def printButtonPressed(self): It could also be a problem with the text editor, you would have to look into it as I'm not experienced with editors outside of vscode.

you could try to repair or reinstall the editor, or just try a new one – Bennett Kohler Apr 17 '23 at 18:34
It's just weird because `self.button.clicked.connect(self.printButtonPressed)` works but there is no suggestion by the IDE that I can use `clicked` and `connect`. – Kacper10714 Apr 17 '23 at 18:38
reinstall all when install python version – Kacper10714 Apr 17 '23 at 18:39

Problem solved. I'm need to convert ".ui' to ".py" and load class Ui_MainWindow.

Example working code (suggestions worked fine).

` from PyQt5 import QtWidgets, uic from PyQt5.QtWidgets import QMainWindow, QAbstractButton import sys from gui import Ui_MainWindow

class Ui(QMainWindow): def init(self): super(Ui, self).init() # uic.loadUi('gui.ui', self)

    self.ui = Ui_MainWindow()
    self.ui.setupUi(self)

    self.ui.printButton.clicked.connect(self.printButtonPressed)

    self.show()

def printButtonPressed(self):
    print('printButtonPressed')

app = QtWidgets.QApplication(sys.argv) window = Ui() app.exec_() `
