Hi, there are two ways. One is to use a binding on the window the other is to use a global: Window bindingimport { VerticalBox } from "std-widgets.slint";
import {MyTextComponent} from "child.slint";
export component AppWindow inherits Window {
in property text-model <=> myteext.model;
callback request-increase-value();
VerticalBox {
mytext := MyTextComponent {
}
}
}let window = AppWindow::new().unwrap();
window.set_text_model(/* set your data here */);
window.run().unwrap();globalimport { VerticalBox } from "std-widgets.slint";
import {MyTextComponent} from "child.slint";
export global Adapter {
in property <[{foo: string, col: color}]> text_model;
}
export component AppWindow inherits Window {
callback request-increase-value();
VerticalBox {
mytext := MyTextComponent {
model: Adapter.text_model;
}
}
}let window = AppWindow::new().unwrap();
Adapter::get(&window).set_text_model(/* set your data here */);
window.run().unwrap(); |

I see, so literally saying, only way to communicate with world is a property drilling. And if there is multiple nesting, it will require drill property all way down, right? Anyway, thanks for the answer. |
