MOUSE_MOVE_EVENT arguments.

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.

modifiers: ModifiersState

What modifier keys where pressed when this event happened.

coalesced_pos: Vec<Point2D<Dip, Dip>>

Positions of the cursor in between the previous event and this one.

Mouse move events can be coalesced, i.e. multiple moves packed into a single event.

position: Point2D<Dip, Dip>

Position of the mouse in the window’s content area.

hits: HitTestInfo

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

target: InteractionPath

Full path to the top-most hit in hits.

capture: Option<CaptureInfo>

Current pointer capture.

Implementations

impl MouseMoveArgs

pub fn new( timestamp: impl Into<DInstant>, propagation_handle: EventPropagationHandle, window_id: impl Into<WindowId>, device_id: impl Into<DeviceId>, modifiers: impl Into<ModifiersState>, coalesced_pos: impl Into<Vec<Point2D<Dip, Dip>>>, position: impl Into<Point2D<Dip, Dip>>, hits: impl Into<HitTestInfo>, target: impl Into<InteractionPath>, capture: impl Into<Option<CaptureInfo>>, ) -> MouseMoveArgs

New args from values that convert into the argument types.

pub fn now( window_id: impl Into<WindowId>, device_id: impl Into<DeviceId>, modifiers: impl Into<ModifiersState>, coalesced_pos: impl Into<Vec<Point2D<Dip, Dip>>>, position: impl Into<Point2D<Dip, Dip>>, hits: impl Into<HitTestInfo>, target: impl Into<InteractionPath>, capture: impl Into<Option<CaptureInfo>>, ) -> MouseMoveArgs

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

impl MouseMoveArgs

pub fn capture_allows(&self) -> bool

If capture is None or allows the WIDGET to receive this event.

pub fn position_wgt(&self) -> Option<Point2D<Px, Px>>

Gets position in the widget inner bounds.

Trait Implementations

impl AnyEventArgs for MouseMoveArgs

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

The target and capture.

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 MouseMoveArgs

fn clone(&self) -> MouseMoveArgs

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for MouseMoveArgs

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

Formats the value using the given formatter.

impl EventArgs for MouseMoveArgs

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

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

Calls handler and stops propagation if propagation is still allowed.
