QListWidget cannot handle too many items

[mr.hichem]

Hello Forum,
i want to add 6573 items to a QListWidget object but it seems like it doesn't that much items, the program seems to stop responding, how can i add that much items into QListWidget?

thanks.

Don't add them one by one but instead do that in chunks. And when you do, disable updates of the widget. An alternative approach is to used model-view architecture instead of QListWidget.
