"""Create a QDrag object with a pixmap of the currently select list item.
This method is useful when you have a QListWidget that displays custom
widgets for each QListWidgetItem instance in the list (usually by calling
``QListWidget.setItemWidget(item, widget)``). When used in a
``QListWidget.startDrag`` method, this function creates a QDrag object that
shows an image of the item being dragged (rather than an empty rectangle).
Parameters
----------
list_widget : QListWidget
The QListWidget for which to create a QDrag object.
Returns
-------
QDrag
A QDrag instance with a pixmap of the currently selected item.
Examples
--------
