KeyChord

Struct KeyChord 

Source
#[non_exhaustive]
pub struct KeyChord { pub key: UiKey, pub modifiers: KeyModifiers, }
Expand description

A keyboard chord for app-level hotkey registration. Match a key with an exact modifier mask: KeyChord::ctrl('f') does not also match Ctrl+Shift+F, and KeyChord::vim('j') does not match if any modifier is held.

Register chords from App::hotkeys; the library matches them against incoming key presses ahead of focus activation routing and emits a UiEvent with kind = UiEventKind::Hotkey and key equal to the registered name.

Fields (Non-exhaustive)§

This struct is marked as non-exhaustive
Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

Implementations§

Source§

impl KeyChord

Source

pub fn vim(c: char) -> Self

A bare key with no modifiers (vim-style). KeyChord::vim('j') matches the j key with no Ctrl/Shift/Alt/Logo held.

Source

pub fn ctrl(c: char) -> Self

Ctrl+<char>.

Source

pub fn ctrl_shift(c: char) -> Self

Ctrl+Shift+<char>.

Source

pub fn named(key: UiKey) -> Self

A named key with no modifiers (e.g. KeyChord::named(UiKey::Escape)).

Source

pub fn with_modifiers(self, modifiers: KeyModifiers) -> Self

Source

pub fn matches(&self, key: &UiKey, modifiers: KeyModifiers) -> bool

Strict match: keys equal AND modifier mask is identical. Holding extra modifiers does not match a chord that didn’t request them.
