FocusNavMeta

Struct FocusNavMeta 

Source
pub struct FocusNavMeta {
    pub focusable: bool,
    pub keyboard_navigable: bool,
    pub order: Option<i32>,
    pub group: Option<FocusSymbol>,
    pub policy_hint: Option<FocusSymbol>,
    pub scope_depth: u8,
    pub autofocus: bool,
    pub enabled: bool,
}
Expand description

Per-element focus navigation metadata kept in the box tree.

Focus eligibility lives here rather than on raw box-tree flags so focus policy remains owned by Floem. keyboard_navigable always implies focusable.

Fields§

§focusable: bool

Whether the element can receive focus by any means.

§keyboard_navigable: bool

Whether the element participates in keyboard traversal.

This always implies focusable.

§order: Option<i32>

Optional explicit linear order key (used for tab traversal).

§group: Option<FocusSymbol>

Optional logical group for policy-aware navigation.

§policy_hint: Option<FocusSymbol>

Optional policy selection hint for host-level policy switching.

§scope_depth: u8

Depth within an app-defined focus scope.

§autofocus: bool

Preferred initial focus candidate for a scope.

§enabled: bool

Additional enable/disable gate independent of focusability.

Implementations§

Source§

impl FocusNavMeta

Source

pub const fn is_focusable(self) -> bool

Returns true when the element can be focused at all.

Source

pub const fn is_keyboard_navigable(self) -> bool

Returns true when the element participates in keyboard focus traversal.

Source

pub fn with_focusable(self, focusable: bool) -> Self

Sets whether the element can receive focus.

Clearing focusable also clears keyboard navigation because keyboard navigation is a stricter form of focusability.

Source

pub fn with_keyboard_navigable(self, keyboard_navigable: bool) -> Self

Sets whether the element participates in keyboard traversal.

Enabling keyboard navigation also enables focusability.

Source

pub fn set_focusable(&mut self, focusable: bool)

Mutates focusability in place.

Source

pub fn set_keyboard_navigable(&mut self, keyboard_navigable: bool)

Mutates keyboard navigation in place.
