How to Temporarily Remove a QListWidget List Without Destroying the Custom Widgets Bound to QListWidgetItems

[kuqipair]

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.

To address this issue,

1. Use takeItem() to remove QListWidgetItems one by one while saving pointers to the items and their associated widgets in a separate list.
2. Reparent the widgets temporarily to avoid deletion.
3. 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.
4. Use a Container to store removed items and their associated widgets.
   Later, reinsert them when restoring the list.

@kuqipair hi,

Taking aside the fact that widget items should be used with caution or rather avoided (for performance reason, etc.), why not switch to a secondary empty QListWidget rather than doing all of that ?
