PyQt5 QListWidget – Getting Batch Size

In this article we will see how we can get the batch size 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 number of items laid out in each batch if layoutMode is set to Batched. The default value is 100 although it can be changed any time with the help of setBatchSize method.

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

Syntax : list_widget.batchSize()

Argument : It takes no argument

Return : It returns integer

Below is the implementation
