Setting border for checkable QListWidgetItem

I have added some check-able QListWidgetItem and I have challenge setting the border color for the checkboxes. setForeground function only sets the color of the checkbox text. Any suggestion please.

This is my sample code creating the check-able QListWidgetItems:

    watch_list = ["Protesters", "Local news staff", "Techfluencers"]
    for category in watch_list:
        self.checkBox = QtWidgets.QListWidgetItem(category)
        self.checkBox.setFlags(self.checkBox.flags() | QtCore.Qt.ItemIsUserCheckable)
        self.checkBox.setCheckState(QtCore.Qt.Unchecked)
        self.checkBox.setForeground(QtGui.QColor('#FFFFFF'))
        self.watchListslistWidget.addItem(self.checkBox)

I have tried

     self.watchListslistWidget.setStyleSheet("""
                                            QListWidget::item {              
                                                 border:1px #FFFFFF
                                            }
                                        """)

But it sets the all background of the QListWidget to white.

Solution

I got it working by using indicator as follows:

self.watchListslistWidget.setStyleSheet("""
                                       QListWidget::indicator{
                                            border: 1px solid white;
                                       }
                                       """)
