Available on crate feature GCLinearInput only.

An object conforming to GCLinearInputrepresents an input that produces normalized values in the unit interval - between [0, 1].

Provided Methods

unsafe fn valueDidChangeHandler( &self, ) -> *mut DynBlock<dyn Fn(NonNull<ProtocolObject<dyn GCPhysicalInputElement>>, NonNull<ProtocolObject<dyn GCLinearInput>>, c_float)>

where Self: Sized + Message,

Available on crate features GCPhysicalInputElement and block2 only.

Set this block to be notified when the value of the input changes.

Parameter element: the element that has been modified.

Parameter input: the input that has been modified.

Parameter value: the value the axis was set to at the time the valueDidChangeHandler fired.

unsafe fn setValueDidChangeHandler( &self, value_did_change_handler: Option<&DynBlock<dyn Fn(NonNull<ProtocolObject<dyn GCPhysicalInputElement>>, NonNull<ProtocolObject<dyn GCLinearInput>>, c_float)>>, )

where Self: Sized + Message,

Available on crate features GCPhysicalInputElement and block2 only.

Setter for valueDidChangeHandler.

unsafe fn value(&self) -> c_float

where Self: Sized + Message,

A normalized value for the axis input, between 0 and 1 (inclusive). The values are deadzoned and saturated before they are returned so there is no value outside the range. Deadzoning does not remove values from the range, the full 0 to 1 magnitude of values are possible from the input.

You can rely on a value of 0 meaning the value is inside the deadzone. Any value greater than zero is not in the deadzone.

unsafe fn isAnalog(&self) -> bool

where Self: Sized + Message,

Check if the input can support more than just digital values.

If YES,the input can produce any value between [0, 1]. Otherwise, the input only produces the values 0 or 1.

unsafe fn canWrap(&self) -> bool

where Self: Sized + Message,

Check if the input value “rolls over” when reaching either the extreme high or low value. For example, some dials can be rotated past the position that represents their maximum value, causing the next reported value to roll over.

Defaults to NO for most inputs.

unsafe fn lastValueTimestamp(&self) -> NSTimeInterval

where Self: Sized + Message,

The timestamp of the last value.

This time interval is not relative to any specific point in time. You can subtract a previous timestamp from the current timestamp to determine the time (in seconds) between changes to the value.

unsafe fn lastValueLatency(&self) -> NSTimeInterval

where Self: Sized + Message,

The interval (in seconds) between the timestamp of the last event and the current time.

This should be treated as a lower bound of the event latency. It may not include (wired or wireless) transmission latency, or latency accrued on the device before the event was transmitted to the host.

unsafe fn sources( &self, ) -> Retained<NSSet<ProtocolObject<dyn GCPhysicalInputSource>>>

where Self: Sized + Message,

Available on crate feature GCPhysicalInputSource only.

An object describing the physical action(s) the user performs to manipulate this input.
