Struct TouchTapArgs

pub struct TouchTapArgs {
    pub timestamp: DInstant,
    pub window_id: WindowId,
    pub device_id: DeviceId,
    pub touch: TouchId,
    pub position: Point2D<Dip, Dip>,
    pub hits: HitTestInfo,
    pub target: InteractionPath,
    pub modifiers: ModifiersState,
    pub tap_count: NonZero<u32>,
    /* private fields */
}

Arguments for TOUCH_TAP_EVENT.

Fields

timestamp: DInstant

Instant the event happened.

window_id: WindowId

Id of window that received the event.

device_id: DeviceId

Id of device that generated the event.

touch: TouchId

Identify the touch contact or finger.

Multiple points of contact can happen in the same device at the same time, this ID identifies each uninterrupted contact. IDs are unique only among other concurrent touches on the same device, after a touch is ended an ID may be reused.

position: Point2D<Dip, Dip>

Center of the touch in the window’s content area.

hits: HitTestInfo

Hit-test result for the touch point in the window.

target: InteractionPath

Full path to the top-most hit in hits.

modifiers: ModifiersState

What modifier keys where pressed when this event happened.

tap_count: NonZero<u32>

Count of taps within the double-tap interval. Number 1 is single tap, 2 is double tap, etc.

Implementations

impl TouchTapArgs

pub fn new( timestamp: impl Into<DInstant>, propagation_handle: EventPropagationHandle, window_id: impl Into<WindowId>, device_id: impl Into<DeviceId>, touch: impl Into<TouchId>, position: impl Into<Point2D<Dip, Dip>>, hits: impl Into<HitTestInfo>, target: impl Into<InteractionPath>, modifiers: impl Into<ModifiersState>, tap_count: impl Into<NonZero<u32>>, ) -> TouchTapArgs

New args from values that convert into the argument types.

pub fn now( window_id: impl Into<WindowId>, device_id: impl Into<DeviceId>, touch: impl Into<TouchId>, position: impl Into<Point2D<Dip, Dip>>, hits: impl Into<HitTestInfo>, target: impl Into<InteractionPath>, modifiers: impl Into<ModifiersState>, tap_count: impl Into<NonZero<u32>>, ) -> TouchTapArgs

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

impl TouchTapArgs

pub fn is_enabled(&self, widget_id: WidgetId) -> bool

If the widget_id is in the target is enabled.

pub fn is_disabled(&self, widget_id: WidgetId) -> bool

If the widget_id is in the target is disabled.

Trait Implementations

impl AnyEventArgs for TouchTapArgs

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

The target.

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

Clone the event into a type erased box.

fn as_any(&self) -> &(dyn Any + 'static)

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 TouchTapArgs

fn clone(&self) -> TouchTapArgs

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for TouchTapArgs

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

Formats the value using the given formatter.

impl EventArgs for TouchTapArgs

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

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