Struct WidgetOpened 

pub struct WidgetOpened<W>(/* private fields */);

Hookable: Triggers when a Widget is created.

Arguments

• The Handle<W> of said Widget.

Aliases

Since every Widget implements the HookAlias trait, instead of writing this in the config crate:

setup_duat!(setup);
use duat::prelude::*;

fn setup() {
    hook::add::<WidgetOpened<LineNumbers>>(|pa, ln| ln.write(pa).relative = true);
}

You can just write this:

setup_duat!(setup);
use duat::prelude::*;

fn setup() {
    hook::add::<WidgetOpened<LineNumbers>>(|pa, ln| ln.write(pa).relative = true);
}

Changing the layout

Assuming you are using duat-term, you could make it so every LineNumbers comes with a VertRule on the right, like this:

setup_duat!(setup);
use duat::prelude::*;

fn setup() {
    hook::add::<WidgetOpened<LineNumbers>>(|pa, handle| {
        VertRule::builder().on_the_right().push_on(pa, handle);
    });
}

Now, every time a LineNumberss Widget is inserted in Duat, a VertRule will be pushed on the right of it. You could even further add a hook on VertRule, that would push further Widgets if you wanted to.
