Struct zng_app::view_process::raw_device_events::KeyArgs

pub struct KeyArgs {
    pub timestamp: DInstant,
    pub device_id: DeviceId,
    pub key_code: KeyCode,
    pub state: KeyState,
    /* private fields */
}

Arguments for the KEY_EVENT.

Fields

timestamp: DInstant

Instant the event happened.

device_id: DeviceId

Keyboard device that generated the event.

key_code: KeyCode

Physical key.

state: KeyState

If the key was pressed or released.

Implementations

impl KeyArgs

pub fn new( timestamp: impl Into<DInstant>, propagation_handle: EventPropagationHandle, device_id: impl Into<DeviceId>, key_code: impl Into<KeyCode>, state: impl Into<KeyState>, ) -> Self

New args from values that convert into the argument types.

pub fn now( device_id: impl Into<DeviceId>, key_code: impl Into<KeyCode>, state: impl Into<KeyState>, ) -> Self

Arguments for event that happened now (INSTANT.now).

Trait Implementations

impl AnyEventArgs for KeyArgs

fn delivery_list(&self, list: &mut UpdateDeliveryList)

Broadcast to all widgets.

fn clone_any(&self) -> Box<dyn AnyEventArgs>

Clone the event into a type erased box.

fn as_any(&self) -> &dyn Any

Access to dyn Any methods.

fn timestamp(&self) -> DInstant

Gets the instant this event happened.

fn propagation(&self) -> &EventPropagationHandle

Propagation handle associated with this event instance.

impl Clone for KeyArgs

fn clone(&self) -> KeyArgs

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for KeyArgs

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

Formats the value using the given formatter.

impl EventArgs for KeyArgs

fn handle<F, R>(&self, handler: F) -> Option<R>

where F: FnOnce(&Self) -> R,

Calls handler and stops propagation if propagation is still allowed.
