How to Temporarily Remove a QListWidget List Without Destroying the Custom Widgets Bound to QListWidgetItems
-
To address this issue,
- Use takeItem() to remove QListWidgetItems one by one while saving pointers to the items and their associated widgets in a separate list.
- Reparent the widgets temporarily to avoid deletion.
- Instead of removing items, they can simply hide all items using QListWidgetItem::setHidden(true).
This keeps the items in memory without actually removing them from the list. - Use a Container to store removed items and their associated widgets.
Later, reinsert them when restoring the list.

I want to temporarily clear a QListWidget. Since each QListWidgetItem in the list is bound to a custom widget, I need to ensure that when removing the list items, the custom widgets are preserved so I can quickly restore the QListWidget later.
