Setting setItemAlignment breaks setSelectionMode in QListWidget

[George55978]

It seems like setting setItemAlignment breaks setSelectionMode in QListWidget.
Here an example:

import sys
from PyQt6.QtWidgets import QApplication, QListWidget, QVBoxLayout, QWidget
from PyQt6.QtCore import Qt

class ListWidgetDemo(QWidget):
    def __init__(self):
        super().__init__()
        layout = QVBoxLayout()
        self.list_widget = QListWidget()
        self.list_widget.setItemAlignment(Qt.AlignmentFlag.AlignLeft)
        self.list_widget.setSelectionMode(QListWidget.SelectionMode.ContiguousSelection)
        for i in range(10):
            self.list_widget.addItem(f"Item {i + 1}")
        layout.addWidget(self.list_widget)
        self.setLayout(layout)

if __name__ == "__main__":
    app = QApplication(sys.argv)
    demo = ListWidgetDemo()
    demo.show()
    sys.exit(app.exec())

It is possible to select multiple items with mouse using item click + mouse drag.
But this is not the case with the item click + Shift + another item click. In the second case , it seems that ContiguousSelection it works the same as SingleSelection.
Is this a bug?

Hi,

It seems you have indeed found something. It's reproducible as well in C++.
You should open a ticket on the bug tracker with you reproducer (don't forget to check if something similar has already been reported).
