I’m working on a PyQt5 application for a course and need to implement a pop-up menu that appears when I right-click on the screen. I attempted to implement it, but I’m encountering an error stating that the PyQtSignal object has no connect attribute. According to the documentation, there should be a connect attribute, so I’m not sure what’s going wrong.

Here is the part of the code concerned:

import os,sys,json
from PyQt5 import QtCore,QtGui,QtWidgets
from PyQt5.QtWidgets import QMessageBox

#from scene import Scene
from view import View

class Window(QtWidgets.QMainWindow):
    def __init__(self,position=(0,0),dimension=(500,300)):
        QtWidgets.QMainWindow.__init__(self)
        #...
        self.view=View()
        self.scene=QtWidgets.QGraphicsScene()  # Model
        self.view.setScene(self.scene)
        self.setCentralWidget(self.view)

        #...

        self.create_actions()
        self.connect_actions()
        self.create_menus()






    # ...



    def connect_actions(self) :


        # This doesnt work
        #self.view.show_popup_menu.connect(self.show_popup_menu_slot)

        # ...

    
    def create_menus(self) :
        #...

        # Popup menu
        self.popupMenu = QtWidgets.QMenu(self)
        popup_menu_style_pen = self.popupMenu.addMenu(QtGui.QIcon("Icons/tool_pen.png"), '&Pen')
        popup_menu_style_pen.addAction(self.action_style_pen_color)
        popup_menu_style_pen.addAction(self.action_style_pen_width)
        popup_menu_style_pen_line = popup_menu_style_pen.addMenu('&Line')
        popup_menu_style_pen_line.addAction(self.action_line_solidline)
        popup_menu_style_pen_line.addAction(self.action_line_dotline)
        popup_menu_style_pen_line.addAction(self.action_line_dashdotline)
        popup_menu_style_brush = self.popupMenu.addMenu(QtGui.QIcon("Icons/brush.png"), '&Brush')
        popup_menu_style_brush.addAction(self.action_style_brush_color)
        popup_menu_style_brush_fill = popup_menu_style_brush.addMenu(QtGui.QIcon("Icons/brush.png"), '&Fill')
        popup_menu_style_brush_fill.addAction(self.action_style_brush_Cross)
        popup_menu_style_brush_fill.addAction(self.action_style_brush_Solid)
        popup_menu_style_brush_fill.addAction(self.action_style_brush_Horizontal)
        popup_menu_style_brush_fill.addAction(self.action_style_brush_Vertical)
        popup_menu_style_brush_fill.addAction(self.action_style_brush_DiagCross)
        popup_menu_style_brush_fill.addAction(self.action_style_brush_None)


    def show_popup_menu_slot(self):
        self.popupMenu.exec_(QtGui.QCursor.pos())

The show_popupmenu is defined in the view constructor in an other file like this:

self.show_popup_menu = QtCore.pyqtSignal()

We have to build our project in those 2 files

I tried to look on the internet, i found stack overflow examples with PyQt4 but it doesnt work in my case
