Enum FocusReason 

#[non_exhaustive]
#[repr(u32)]
pub enum FocusReason {
    Programmatic = 0,
    TabNavigation = 1,
    PointerClick = 2,
    PopupActivation = 3,
    WindowActivation = 4,
}

This enum describes the different reasons for a FocusEvent

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Programmatic = 0

A built-in function invocation caused the event (.focus(), .clear-focus())

TabNavigation = 1

Keyboard navigation caused the event (tabbing)

PointerClick = 2

A mouse click caused the event

PopupActivation = 3

A popup caused the event

WindowActivation = 4

The window manager changed the active window and caused the event

Trait Implementations

impl Clone for FocusReason

fn clone(&self) -> FocusReason

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FocusReason

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

Formats the value using the given formatter.

impl Default for FocusReason

fn default() -> Self

Returns the “default value” for a type.

impl Display for FocusReason

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

Formats the value using the given formatter.

impl FromStr for FocusReason

type Err = ParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<FocusReason, <Self as FromStr>::Err>

Parses a string s to return a value of this type.

impl Hash for FocusReason

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for FocusReason

fn eq(&self, other: &FocusReason) -> 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.

impl TryFrom<&str> for FocusReason

type Error = ParseError

The type returned in the event of a conversion error.

fn try_from(s: &str) -> Result<FocusReason, <Self as TryFrom<&str>>::Error>

Performs the conversion.
