PyQt5 QSpinBox - Getting native parent widget

In PyQt5, the nativeParentWidget() method returns the closest ancestor of the widget (including the widget itself) that is a native widget. A native widget is a platform-specific widget at the lowest level, corresponding to the windowing system. This method is useful in scenarios where you need to interact with platform-specific properties or when dealing with advanced window handling tasks.

Here's an example of using nativeParentWidget() with a QSpinBox inside a QMainWindow:

import sys from PyQt5.QtWidgets import QApplication, QMainWindow, QSpinBox, QVBoxLayout, QWidget, QLabel class App(QMainWindow): def __init__(self): super().__init__() self.setGeometry(100, 100, 400, 300) self.central_widget = QWidget() self.layout = QVBoxLayout() self.spin_box = QSpinBox(self.central_widget) self.layout.addWidget(self.spin_box) # Get native parent widget of QSpinBox native_parent = self.spin_box.nativeParentWidget() label_text = "QSpinBox's native parent is of type: " + str(type(native_parent)) self.label = QLabel(label_text) self.layout.addWidget(self.label) self.central_widget.setLayout(self.layout) self.setCentralWidget(self.central_widget) if __name__ == '__main__': app = QApplication(sys.argv) window = App() window.show() sys.exit(app.exec_())

In this code, when you run the application, you'll see a QSpinBox and a QLabel indicating the type of the native parent widget of the QSpinBox. Typically, for a widget inside a QMainWindow, the native parent would be the QMainWindow itself.
