How to iterate over property values using 'for' loop?

[wwstory]

I try iterate over property in callback function, but it seems that it doesn't have such functionality. I just want to implement a feature for selecting all items in a table view. I prefer not to use Rust/C++, and it would be more reasonable for this to be implemented by the UI.

example: https://slint.dev/releases/1.3.2/docs/slint/src/recipes/recipes#custom-table-view

like this.

CheckBox {
    toggled => {
        // root.values[:] = self.checked;
        for r[i] in root.values {
            r.select = self.checked;
        }
    }
}

We are trying to prevent turning the Slint language into a programming language. We want to avoid making it possible to write the logic in the .slint file.
So you will have to do such logic in Rust or C++

I tried to solve it only in Slint, in case a purely visual indication would suffice, but it does not work because toggling a checkbox destroys any binding to its checked property (Slintpad). And I don't think there is currently any way to restore this binding?

It's a bit unfortunate, but in such a case, then one would indeed need to expose a logic function to set the selected state, which would probably restore the binding as a result of re-creating the items due to the change callback from the data model?

Use recursion?
