simplest mvc pattern in pyside6

abiabi

iam looking for simple skelton of mvc pattern implemented in pyside6.

i know a bit about mvc i found simple code with help of AI but the problem is all of the mvc patterns uses a centralized approach,

iam looking for a decentralized approach like attaching controller with specific view.so every widget can have its own controller.so i dont have to write every sub widgets code in main.py file.

is it actually possible.below is code generated AI

from PySide6.QtWidgets import QApplication, QWidget, QVBoxLayout, QPushButton, QLabel
from PySide6.QtCore import QObject, Signal
import sys

# Model: Stores count and emits updates
class CounterModel(QObject):
    updated = Signal(int)

    def __init__(self):
        super().__init__()
        self.count = 0

    def update(self, value):
        self.count += value
        self.updated.emit(self.count)

# View: UI elements
class CounterView(QWidget):
    def __init__(self):
        super().__init__()
        self.setWindowTitle("Simple MVC - PySide6")
        layout = QVBoxLayout(self)

        self.label = QLabel("Count: 0")
        self.inc_btn = QPushButton("Increment")
        self.dec_btn = QPushButton("Decrement")

        layout.addWidget(self.label)
        layout.addWidget(self.inc_btn)
        layout.addWidget(self.dec_btn)

# Controller: Connects model and view
class CounterController:
    def __init__(self, model, view):
        self.model = model
        self.view = view

        self.view.inc_btn.clicked.connect(lambda: self.model.update(1))
        self.view.dec_btn.clicked.connect(lambda: self.model.update(-1))
        self.model.updated.connect(lambda value: self.view.label.setText(f"Count: {value}"))

# Main Application
if __name__ == "__main__":
    app = QApplication(sys.argv)
    model = CounterModel()
    view = CounterView()
    controller = CounterController(model, view)

    view.show()
    sys.exit(app.exec())

Hi,

Did you already took a look at Qt's model view implementation ?

In case you need some guidance, here is an auto-translate (C++ -> Python) for the snippet within that page https://doc.qt.io/qtforpython-6/overviews/qtwidgets-model-view-programming.html (some of the code might not be 100% working but it might be hopefully a starting point)
