Provided Methods

unsafe fn absoluteInput( &self, ) -> Option<Retained<ProtocolObject<dyn GCAxisInput>>>

where Self: Sized + Message,

Available on crate feature GCAxisInput only.

The input reporting the value of the axis as the position between a lower and upper bound, if available.

unsafe fn relativeInput(&self) -> Retained<ProtocolObject<dyn GCRelativeInput>>

where Self: Sized + Message,

Available on crate feature GCRelativeInput only.

The input reporting axis values as the change (delta) since the last event.

Certain kinds of axis elements are only able to report relative values. The tracking of a computer mouse, for example, has no fixed origin - only the change in position since the last event is reported. Some freely-rotating dials may also only report a value indicating which direction the dial was turned.

impl ProtocolType for dyn GCAxisElement

const NAME: &'static str = "GCAxisElement"

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
