Struct KeyDownWatchEntry 

pub struct KeyDownWatchEntry {
    pub name: String,
    pub swallow: Vec<Key>,
    pub target: Option<Entity>,
}

One entry in NoesisKeyDownWatch: an element x:Name, the per-name swallow set, and the entity the resulting UiKeyDown should target. Keys in swallow are marked handled by the C++ trampoline, stopping further routing (e.g. swallow Return so a submit doesn’t append a newline). Empty by default: every key propagates, none are swallowed. target defaults to the view entity.

Fields

name: String

x:Name of the element to watch for UIElement::KeyDown.

swallow: Vec<Key>

Keys marked handled by the C++ trampoline, stopping further routing.

target: Option<Entity>

Entity the fired UiKeyDown targets; None → the view entity.

Builder: append key to the swallow set.

pub fn swallow_all<I>(self, keys: I) -> Self

where I: IntoIterator<Item = Key>,

Builder: append every key in keys to the swallow set.

pub fn target(self, target: Entity) -> Self

Builder: target the fired UiKeyDown at target instead of the view.
