Struct TOUCH

source

pub struct TOUCH;

Expand description

Touch service.

§Touch Capture

Touch capture is integrated with mouse capture in the POINTER_CAPTURE service.

§Provider

This service is provided by the TouchManager extension.

Implementations§

source §

impl TOUCH

source

pub fn touch_config(&self) -> ArcCowVar<TouchConfig, ArcVar<TouchConfig>>

Variable that defines the touch config for the app.

The value is the same as sys_touch_config, if set the variable disconnects from system config.

source

pub fn sys_touch_config(&self) -> ReadOnlyVar<TouchConfig, ArcVar<TouchConfig>>

Read-only variable that tracks the system touch config.

Note that some of these configs are not always used, a tap event for example can happen even if the touch moves out of the tap_area when there is no ambiguity.

§Value Source

The value comes from the operating system settings, the variable updates with a new value if the system setting is changed and on view-process (re)init.

In headless apps the default is TouchConfig::default and does not change.

source

pub fn positions( &self, ) -> ReadOnlyVar<Vec<TouchPosition>, ArcVar<Vec<TouchPosition>>>

Variable that tracks all current active touches.

source

pub fn touch_from_mouse_events(&self) -> ArcVar<bool>

Test mode, generates touch events for a single touch contact from raw mouse events.

Is disabled by default.

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

source §

impl<T> Borrow<T> for T
where T: ?Sized,

source §

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more

where T: ?Sized,

source §

fn borrow_mut(&mut self) -> &mut T

Mutably borrows from an owned value. Read more

§

impl<T> Downcast for T
where T: Any,

§

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.

§

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.

§

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

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s.

§

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

Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s.

§

impl<T> DowncastSync for T
where T: Any + Send + Sync,

§

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Sync + Send>

Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait.

source §

impl<T> IntoEither for T

source §

fn into_either(self, into_left: bool) -> Either<Self, Self>

source §

fn into_either_with<F>(self, into_left: F) -> Either<Self, Self>
where F: FnOnce(&Self) -> bool,

Converts self into a Left variant of Either<Self, Self> if into_left(&self) returns true. Converts self into a Right variant of Either<Self, Self> otherwise. Read more
