I’m working on a PyQt6 application and I’ve encountered an issue where clicking a button does not trigger the connected method. I’ve broken down my project into three main files: the main window, the buttons layout, and an example.

MainWindow.py

import sys
from PyQt6.QtWidgets import QMainWindow, QApplication, QWidget, QGridLayout
from .right_buttons.right_buttons import RightButtons

class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__(parent=None)
        self.setWindowTitle("Vocanki")
        
        self.mainWidget = QWidget(self)  # Central widget
        self.setCentralWidget(self.mainWidget)
        
        central_grid_layout = QGridLayout(self.mainWidget)
        right_buttons = RightButtons(central_grid_layout, vocabulary_manager)
        
        central_grid_layout.addLayout(right_buttons.right_vertical_layout, 0, 1)
    
if __name__ == "__main__":
    app = QApplication(sys.argv)
    main_window = MainWindow()
    
    main_window.show()
    
    sys.exit(app.exec())

right_buttons.py

from PyQt6.QtWidgets import QVBoxLayout, QPushButton
from .one_kanji_button import OneKanjiButton

class RightButtons:
    def __init__(self, central_grid_layout, vocabulary_manager):
        self.right_vertical_layout = QVBoxLayout()
        
        self.one_kanji_button = OneKanjiButton(vocabulary_manager) 
        self.right_vertical_layout.addLayout(self.one_kanji_button.layout)
        self.right_vertical_layout.addWidget(QPushButton("Top"))
        self.right_vertical_layout.addWidget(QPushButton("Top"))

one_kanji_button.py

from PyQt6.QtWidgets import QWidget, QHBoxLayout, QFormLayout, QLineEdit, QPushButton

class OneKanjiButton(QWidget):
    def confirm(self):
        print(self.kanji_line_edit.text())
    
    def __init__(self, vocabulary_manager):
        super().__init__()
        self.vocabulary_manager = vocabulary_manager
        
        self.layout = QHBoxLayout()
        
        self.formLayout = QFormLayout()
        self.kanji_line_edit = QLineEdit()
        self.formLayout.addRow("Enter Kanji:", self.kanji_line_edit)
        self.enter_button = QPushButton("Confirm")
        
        self.enter_button.clicked.connect(self.confirm)
        
        self.layout.addLayout(self.formLayout)
        self.layout.addWidget(self.enter_button)

I instantiate the “enter_button” as a QPushButton and connect the signal to the “confirm” method. However, when pressing this button, nothing happens.
When I instantiate this button in the “MainWindow” class, it works.

Any insights?
