Struct Pointer 

pub struct Pointer { /* private fields */ }

Identifies a specific input pointer and tracks the element that captures it.

Implementations

impl Pointer

pub fn get_next_free_id() -> i32

Returns a pointer identifier that is not in use.

pub fn new(id: i32, type_: PointerType, is_primary: bool) -> Rc<Pointer>

Creates a pointer.

pub fn with_platform_capture( id: i32, type_: PointerType, is_primary: bool, platform_capture: impl Fn(Option<&Ref<InputElement>>) + 'static, ) -> Rc<Pointer>

Creates a pointer that captures the pointer in the platform through platform_capture whenever the capturing element changes.

pub fn platform_capture_lost(&self)

Notifies the pointer that its capture was lost in the platform.

pub fn capture_with_source( &self, control: Option<&Ref<InputElement>>, source: CaptureSource, )

Captures pointer input to the specified control, on behalf of source.

pub fn captured_gesture_recognizer(&self) -> Option<Ref<GestureRecognizer>>

The gesture recognizer that captures the pointer, if any.

pub fn capture_source(&self) -> CaptureSource

What requested the current capture state.

pub fn is_gesture_recognition_skipped(&self) -> bool

Whether gesture recognition is skipped for the pointer until it is released.

pub fn set_is_gesture_recognition_skipped(&self, value: bool)

Sets whether gesture recognition is skipped for the pointer.

pub fn dispose(&self)

Releases the pointer: its capture is lost and it can no longer be captured.

Trait Implementations

impl IPointer for Pointer

fn id(&self) -> i32

The unique identifier of the pointer.

fn capture(&self, control: Option<&Ref<InputElement>>)

Captures pointer input to the specified control.

fn captured(&self) -> Option<Ref<InputElement>>

The control that is currently capturing the pointer, if any.

fn type_(&self) -> PointerType

The type of the pointer.

fn is_primary(&self) -> bool

Whether the pointer is the primary pointer of its type.

fn as_any(&self) -> &dyn Any

The pointer as Any, for downcasting to the concrete pointer.
