How do I bind a Rust VecModel to a component property?

[poperigby]

I have this struct that I'm going to encapsulate in a VecModel:

#[derive(Debug, Clone)]
pub struct ResolvedModEntry {
    mod_ref: Mod,
    entry: ModEntry,
}

I'd like to then bind this model to a StandardTableView. I'm not really sure how to do this though. The documentation seems to be somewhat lacking on VecModels and StandardTableViews, or maybe I'm just not looking in the right place.

For one thing, it won't recognize the type if I try to set the property up like this:

export component ModTableView {
    in property <[ResolvedModEntry]> model;

    StandardTableView {}
}

Here's my code: https://github.com/poperigby/barnacle/

Sorry if I am a bit late to the party. To make Slint aware of those structs you'll have to write those data structs from within Slint. Assuming Mod and ModEntry are also structs:

export struct Mod { /*  put the fields here */ }

export struct ModEntry { /*  put the fields here */ }

export struct ResolvedModEntry {
    mod_ref: Mod,
    entry: ModEntry,
}

Those structs are then available as regular Rust structs.

If you want to start with a StandardTableView you'll have to create a two-dimensional Vec in Rust and copy the display data to StandardListviewItem's text property. Just wrote an example for StandardTableView few days ago for this discussion.

With a ListView you are more flexible and populate the model with the for statement.

export AppWindow inherits Window {
    in property <[ResolvedModEntry]> mod_model;

    VerticalBox {
        list := ListView {
             for e in root.mod_model: Rectangle {
                 HorizontalLayout {
                      Text {
                          text: e.entry.name;  // assuming a name field exists in mod
                      }
                 } 
             }
        }
    }
}
