How can I add Icons to a QListWidget

Question

I have a program that has you drag and drop files into a QListWidget box and then you click a button to upload those files to a bucket. I would like to say which files have been uploaded and which one is currently being uploaded with an icon. Is there a way to add Icons inside/next to the QListWidget box?

Here is some of the code for the QListWidget and the drag and drop feature. I am just hoping there is a way to add icons

import sys, os
from PyQt5.QtWidgets import QApplication, QMainWindow, QListWidget, QListWidgetItem, QPushButton
from PyQt5.QtCore import Qt, QUrl
 
class ListBoxWidget(QListWidget):
    def __init__(self, parent=None):
        super().__init__(parent)
        self.setAcceptDrops(True)
        self.resize(600, 600)
 
    def dragEnterEvent(self, event):
        if event.mimeData().hasUrls:
            event.accept()
        else:
            event.ignore()
 
    def dragMoveEvent(self, event):
        if event.mimeData().hasUrls():
            event.setDropAction(Qt.CopyAction)
            event.accept()
        else:
            event.ignore()
 
    def dropEvent(self, event):
        if event.mimeData().hasUrls():
            event.setDropAction(Qt.CopyAction)
            event.accept()
 
            links = []
            for url in event.mimeData().urls():
                # https://doc.qt.io/qt-5/qurl.html
                if url.isLocalFile():
                    links.append(str(url.toLocalFile()))
                else:
                    links.append(str(url.toString()))
            self.addItems(links)
        else:
            event.ignore()
 
class AppDemo(QMainWindow):
    def __init__(self):
        super().__init__()
        self.resize(1200, 600)
 
        self.listbox_view = ListBoxWidget(self)
 
        self.btn = QPushButton('Get Value', self)
        self.btn.setGeometry(850, 400, 200, 50)
        self.btn.clicked.connect(lambda: print(self.getSelectedItem()))
 
    def getSelectedItem(self):
        item = QListWidgetItem(self.listbox_view.currentItem())
        return item.text()
 
 
 
if __name__ == '__main__':
    app = QApplication(sys.argv)
 
    demo = AppDemo()
    demo.show()
 
    sys.exit(app.exec_())

I have tried adding QIcon to the self.addItems(links) line but it continues to give me an error about arguments.

Instead of adding items using addItems, create indivual QListWidgetItems and add them one by one using addItem(QListWidgetItem).

def dropEvent(self, event):
    if event.mimeData().hasUrls():
        event.setDropAction(Qt.CopyAction)
        event.accept()

        for url in event.mimeData().urls():
            # https://doc.qt.io/qt-5/qurl.html
            if url.isLocalFile():
                address = str(url.toLocalFile())
                icon = QIcon('localIcon.png')
            else:
                address = str(url.toString())
                icon = QIcon('remoteIcon.png')
            self.addItem(QListWidgetItem(icon, address))

If you want to change the icon of an existing item, access it using item() and use setIcon():

def setIconForItem(self, row, icon):
    self.listbox_view.item(row).setIcon(icon)
