从 QDialog 到 QWidget 通信，反之亦然

Question

I need to show the QDialog when the user presses a button in the QWidget, and to repopulate a QTableWidget that is in the QWidget when the user presses a button in the QDialog. When I try doing it as bellow it gives me this error: RecursionError: maximum recursion depth exceeded

# Summary of the Code:

class SettingsWindow(QWidget):
    def __init__(self):
        super().__init__()

        self.inventory_dialog = inventory_dialog()

        self.bmodify_inventario = QPushButton(self.precios)
        self.bmodify_inventario.clicked.connect(self.modify_inventario)


        def modify_inventario(self):

            conn = sqlite3.connect(database)
            c = conn.cursor()
    
            c.execute("SELECT producto FROM inventario")
            list_productos = c.fetchall()

            self.inventory_dialog.producto_input.addItems(
                [i for sub in list_productos for i in sub])

            self.inventory_dialog.deposito_input.addItems(["dep1","dep2", "dep3"])

            conn.close()

            self.inventory_dialog.show()
     

class inventory_dialog(QWidget):
    def __init__(self):
        super().__init__()

        self.SettingsWindow = SettingsWindow()

        self.brepopulate = QPushButton(self)
        self.brepopulate.clicked.connect(self.repopulate)

    def repopulate(self):

        conn = sqlite3.connect(database)

        c = conn.cursor()

        c.execute(
            "SELECT * FROM inventario")
        data = c.fetchall()

        self.SettingsWindow.inventario_table.setRowCount(len(data))

        table_row = 0
        for row in data:
            self.SettingsWindow.inventario_table.setItem(
                table_row, 0, QtWidgets.QTableWidgetItem(row[0]))
            self.SettingsWindow.inventario_table.setItem(
                table_row, 1, QtWidgets.QTableWidgetItem(row[1]))
            self.SettingsWindow.inventario_table.setItem(
                table_row, 2, QtWidgets.QTableWidgetItem(row[2]))
            self.SettingsWindow.inventario_table.setItem(
                table_row, 3, QtWidgets.QTableWidgetItem(row[3]))
            self.SettingsWindow.inventario_table.setItem(
                table_row, 4, QtWidgets.QTableWidgetItem(row[4]))
            self.SettingsWindow.inventario_table.setItem(
                table_row, 5, QtWidgets.QTableWidgetItem(row[5]))
            table_row += 1
           

My Idea for solving this was to repopulate the QTableWidget from the QDialog, but can't get it working.

Everytime SettingsWindow opens inventory_dialog :

 def __init__(self):
        super().__init__()

        self.inventory_dialog = inventory_dialog()

inventory_Dialog opens SettingsWindow ...

 def __init__(self):
        super().__init__()

        self.SettingsWindow = SettingsWindow()

And it keeps going on forever...
