Struct bevy_ui_navigation::Focused

source · [−]

#[non_exhaustive]
pub struct Focused;

Expand description

The currently focused Focusable.

You cannot edit it or create new Focused component. To set an arbitrary Focusable to focused, you should send NavRequest::FocusOn.

This Component is useful if you need to query for the currently focused element using a Query<Entity, With<Focused>> for example.

If a Focusable is focused, its Focusable::state() will be FocusState::Focused, if you have a Focusable but can’t query filter on Focused, you can check for equality.

Notes

The Focused marker component is only updated at the end of the CoreStage::Update stage. This means it might lead to a single frame of latency compared to using Focusable::state().
