Creating a Column with a Vector of Strings

[aadityadhruv]

I am still new to Rust, so I am not sure if this stems from my lack of understanding of Rust or Iced. I am trying to learn Iced & Rust, and am experimenting with the library. I have a Vec<String> which I would like to display as a column. However, looking at the column function implementation, the children parameter has type Vec<Element<'_, Message, Renderer>, Global>. Firstly, I am not too sure I understand what this signature means. I understand that there is a generic type in the Element part, but what are the Message, Renderer and Global parts?

Secondly, how would I go about making a column with a vector of strings? I could iter() and map it into some Element but I am not sure how that works or what that means.

You will need to create a Text widget for each String in you collection and then you can either use with_children to create the Column with all its children in one go or push to add items one by one.

    fn view(&self) -> iced::Element<Message> {
        let mut window = iced::widget::Column::with_children(vec![
            iced::widget::Text::new("hello").into(),
            iced::widget::Text::new("world").into(),
        ]);
        window = window.push(iced::widget::Text::new("!"));
        return window.into();
    }

Notice how with_children requires a vector of Elements, so I call into() on my widgets, but push only requires an Into<Element> so I can pass the widget directly.

There are also some macros and helper functions that make the whole thing look simpler, although I'm just finding out about them now.

    fn view(&self) -> iced::Element<Message> {
        let mut window = iced::widget::column![
            iced::widget::text("hello"),
            iced::widget::text("world"),
        ];
        window = window.push(iced::widget::text("!"));
        return window.into();
    }
