Cannot get value of an input field-CodePudding

I cannot seem to get the value of the input field.

The error I get is 'bool' object has no attribute 'input'. Yet I am fairly certain I have set the pointer up properly.

I have tried converting the Ui file to Py and still get the same result. I feel like I am calling the wrong object here, but every tutorial online shows using .text() to get the value of a QLineEdit child.

Python File:

from PyQt5 import QtWidgets, uic
import sys


class Ui(QtWidgets.QMainWindow):
    def __init__(self):
        super(Ui, self).__init__() # Call the inherited classes __init__ method
        uic.loadUi('main.ui', self) # Load the .ui file
        self.show() # Show the GUI

        self.button = self.findChild(QtWidgets.QPushButton, 'Button')
        self.button.clicked.connect(Ui.button_pressed)

        self.input = self.findChild(QtWidgets.QLineEdit, 'userInput')

    def button_pressed(self):
        print("Hello"   self.input.text())


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

CodePudding user response：

Using self.button.clicked.connect(self.button_pressed) works. The argument passed as "self" to Ui.button_pressed appears to just be a bool indicating if it was clicked (I'm honestly not sure), rather then 'self' (the actual class instantiation).

CodePudding user response：

The issue is due to the keyword self being set to a boolean. Hence, self.input generates the error you encountered. As Alec points out, the self is not being set correctly as you are passing Ui.button_pressed instead of self.button_pressed as the argument to self.button.clicked.connect().
