init from a Window should work like "onload" event?

[microhobby]

Hey everyone, I'm new to Slint, and I'm using the following:

• appwindow.slint:

import { 
    Button,
    HorizontalBox,
    VerticalBox,
    AboutSlint 
} from "std-widgets.slint";

export component AppWindow inherits Window {
    in-out property<int> counter: 42;
    in-out property<string> vendor;
    callback request-increase-value();
    callback request-vendor-name();

    init => {
        root.request-vendor-name();
    }

    VerticalBox {
        AboutSlint {
        }
        Text {
            horizontal-alignment: center;
            text: "openGL: \{root.vendor}";
        }
        Text {
            horizontal-alignment: center;
            text: "Counter: \{root.counter}";
        }
        HorizontalBox {
            alignment: center;
            Button {
                text: "Increase value";
                clicked => {
                    root.request-increase-value();
                }
            }
        }
     }
}

• main.rs:

slint::include_modules!();

fn main() -> Result<(), slint::PlatformError> {
    let ui = AppWindow::new()?;

    let ui_handle = ui.as_weak();
    ui.on_request_increase_value(move || {
        let ui = ui_handle.unwrap();
        ui.set_counter(ui.get_counter() + 1);
    });

    let ui_handle = ui.as_weak();
    ui.on_request_vendor_name(move || {
        let ui = ui_handle.unwrap();
        ui.set_vendor("Test".into());
    });

    ui.run()
}

But the code from on_request_vendor_name is not running on the show of the Window. I'm doing something wrong, or is my inference that this should run in the window show is wrong?

Hi! The init callback is invoked when the Window is constructed, so that's before your call to on_request_vendor_name. In this case you don't really need init, you can just set the vendor property directly.
