QListWidget, no item was selected

[Axel_Erfurt]

deanhystad's solution also works.

import sys
from PyQt6.QtWidgets import (QApplication, QMainWindow,  QGridLayout, QListWidget)


class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()

        self.setWindowTitle('Test')
        self.setGeometry(100, 100, 400, 100)
        
        self.list_widget = QListWidget()
        self.list_widget.addItems(['Hello', 'World'])
        self.setCentralWidget(self.list_widget)
        
        self.check_selected()
        
        self.list_widget.setCurrentRow(1)
        
        self.check_selected()
        
        self.show()
        
        
    def check_selected(self):
        if not self.list_widget.selectedItems():
            print("nothing selected")
        else:
            print(f"row {self.list_widget.currentRow()} selected")


if __name__ == '__main__':
    app = QApplication(sys.argv)
    window = MainWindow()
    sys.exit(app.exec())

Output:
nothing selected
row 1 selected
