Implementations

impl PointerCaptureArgs

pub fn new( timestamp: impl Into<DInstant>, propagation_handle: EventPropagationHandle, prev_capture: impl Into<Option<CaptureInfo>>, new_capture: impl Into<Option<CaptureInfo>>, ) -> Self

New args from values that convert into the argument types.

pub fn now( prev_capture: impl Into<Option<CaptureInfo>>, new_capture: impl Into<Option<CaptureInfo>>, ) -> Self

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

impl PointerCaptureArgs

pub fn is_widget_move(&self) -> bool

If the same widget has pointer capture, but the widget path changed.

pub fn is_mode_change(&self) -> bool

If the same widget has pointer capture, but the capture mode changed.

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

If the widget_id lost pointer capture with this update.

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

If the widget_id got pointer capture with this update.

Trait Implementations

impl AnyEventArgs for PointerCaptureArgs

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

The prev_capture and new_capture paths start with the current path.

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 PointerCaptureArgs

fn clone(&self) -> PointerCaptureArgs

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PointerCaptureArgs

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

Formats the value using the given formatter.

impl EventArgs for PointerCaptureArgs

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

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

Calls handler and stops propagation if propagation is still allowed.
