Struct zng_app::access::AccessIncrementArgs

pub struct AccessIncrementArgs {
    pub timestamp: DInstant,
    pub window_id: WindowId,
    pub widget_id: WidgetId,
    pub delta: i32,
    /* private fields */
}

Arguments for the ACCESS_INCREMENT_EVENT.

Fields

timestamp: DInstant

Instant the event happened.

window_id: WindowId

Target window.

widget_id: WidgetId

Target widget.

delta: i32

Increment steps.

Usually is -1 or 1.

Implementations

impl AccessIncrementArgs

pub fn new( timestamp: impl Into<DInstant>, propagation_handle: EventPropagationHandle, window_id: impl Into<WindowId>, widget_id: impl Into<WidgetId>, delta: impl Into<i32>, ) -> Self

New args from values that convert into the argument types.

pub fn now( window_id: impl Into<WindowId>, widget_id: impl Into<WidgetId>, delta: impl Into<i32>, ) -> Self

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

Trait Implementations

impl AnyEventArgs for AccessIncrementArgs

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

Target the widget.

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 AccessIncrementArgs

fn clone(&self) -> AccessIncrementArgs

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AccessIncrementArgs

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

Formats the value using the given formatter.

impl EventArgs for AccessIncrementArgs

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

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

Calls handler and stops propagation if propagation is still allowed.
