Struct FocusManager 

pub struct FocusManager;

Moves focus between the focus targets the tree holds, the way LocalFocusManager does in Jetpack Compose.

let focus = cranpose_ui::local_focus_manager().current();
focus.move_focus(FocusDirection::Next);
focus.clear_focus();

Tab and Shift+Tab reach this through the app shell, so an app that puts Modifier::focusable() on its controls gets keyboard traversal with no further code.

Implementations

impl FocusManager

pub fn move_focus(&self, direction: FocusDirection) -> bool

Moves focus one step in direction. Answers whether focus moved.

pub fn clear_focus(&self) -> bool

Drops focus from whatever holds it, and answers whether one held it. Compose takes a force flag here for targets that refuse to give focus up; no target in Cranpose refuses, so this always clears.
