PyQt5 QListWidget – Setting Auto Scroll Margin

In this article we will see how we can set auto scroll margin of the QListWidget. QListWidget is a convenience class that provides a list view with a classic item-based interface for adding and removing items. QListWidget uses an internal model to manage each QListWidgetItem in the list. This property holds the size of the area when auto scrolling is triggered. This property controls the size of the area at the edge of the viewport that triggers autoscrolling. The default value is 16 pixels.

In order to do this we will use setAutoScrollMargin method with the list widget object.

Syntax : list_widget.setAutoScrollMargin(n)

Argument : It takes integer as argument

Return : It returns None

Below is the implementation
