Enum FocusState 

pub enum FocusState {
    Inactive,
    ActiveParent,
    Active,
    Captured,
}

Focus state for a registered focus node.

Use this to render focus-dependent UI and distinguish between the primary focused target and its focused ancestors.

Examples

use tessera_ui::FocusState;

assert!(!FocusState::Inactive.has_focus());
assert!(FocusState::ActiveParent.has_focus());
assert!(FocusState::Active.is_focused());
assert!(FocusState::Captured.is_captured());

Variants

Inactive

The node is not participating in the active focus path.

ActiveParent

A descendant of this node currently holds focus.

Active

This node currently holds focus.

Captured

This node currently holds captured focus.

Implementations

impl FocusState

pub fn has_focus(self) -> bool

Returns true when this node is in the active focus path.

pub fn is_focused(self) -> bool

Returns true when this node is the primary focused node.

pub fn is_captured(self) -> bool

Returns true when this node has captured focus.

Trait Implementations

impl Clone for FocusState

fn clone(&self) -> FocusState

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FocusState

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for FocusState

fn default() -> FocusState

Returns the “default value” for a type.

impl PartialEq for FocusState

fn eq(&self, other: &FocusState) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
