in iOS，tableview.reload to refresh the list.

i can't find a way to reload the slint listview in slint side or rust side.

Not exactly sure what you are trying to achieve, but the way to do it would be typically to set the model to a new model.
Or get the reset function of the model called.

If your hub-infos are backed by a VecModel, then you can use its remove function to remove an item from the model. It will then automatically be removed from the list view.

To reset the entire model, you can either create a new model instance and assign it to your DataHub.hub-infos global, or replace the contents of the existing model using set_vec. I'm doing this in my application as follows:

https://github.com/bjorn/raccoin/blob/304215415852eccae928259317227cb22c65d08e/src/main.rs#L1337-L1339

Though it's a bit more complicated than necessary, since I could not keep a ModelRc reference around in my app data due to some async code. I'd recommend keeping an Rc<VecModel<...>> reference around if possible.

(hmm, the post I've answered appears to be gone)
