Struct WidgetCreated

pub struct WidgetCreated<W: Widget<U>, U: Ui>(/* private fields */);

Hookable: Triggers when a Widget’s cfg is created

Arguments

• The WidgetCfg in question.
• The FileHandle to which it was pushed, if there was one.

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::<WidgetCreated<LineNumbers<Ui>>>(|pa, (ln, handle)| ln.rel_abs());
}

You can just write this:

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

fn setup() {
    hook::add::<LineNumbers<Ui>>(|pa, (ln, handle)| ln.rel_abs());
}

Do note that this hook doesn’t let you change the layout of the pushed Widgets, only their configuration. So if one of these changes changed the direction where the Widget was pushed, for example, the layout could get messed up.

If you want to change the layout of the Widgets in a controled fashion, look at OnFileOpen and OnWindowOpen.

Trait Implementations

impl<W: Widget<U>, U: Ui> Hookable for WidgetCreated<W, U>

type Input<'h> = (<W as Widget<U>>::Cfg, Option<&'h FileHandle<U>>)

The arguments that are passed to each hook.

type Output = <W as Widget<U>>::Cfg

The output of triggering hooks. Mostly never used

fn get_input(&mut self) -> Self::Input<'_>

How to get the arguments from the Hookable

fn take_output_back(&mut self, output: Self::Output)

When a Hookable has an Output, you can define how it takes it back
