Provided Methods

unsafe fn positionDidChangeHandler( &self, ) -> *mut DynBlock<dyn Fn(NonNull<ProtocolObject<dyn GCPhysicalInputElement>>, NonNull<ProtocolObject<dyn GCSwitchPositionInput>>, NSInteger)>

where Self: Sized + Message,

Available on crate features GCPhysicalInputElement and block2 only.

Set this block if you want to be notified when the value on the switch changes.

Parameter input: the element that has been modified.

See: value

unsafe fn setPositionDidChangeHandler( &self, position_did_change_handler: Option<&DynBlock<dyn Fn(NonNull<ProtocolObject<dyn GCPhysicalInputElement>>, NonNull<ProtocolObject<dyn GCSwitchPositionInput>>, NSInteger)>>, )

where Self: Sized + Message,

Available on crate features GCPhysicalInputElement and block2 only.

Setter for positionDidChangeHandler.

unsafe fn position(&self) -> NSInteger

where Self: Sized + Message,

The switch’s position.

See: valueDidChangeHandler

unsafe fn positionRange(&self) -> NSRange

where Self: Sized + Message,

The (inclusive) bounds of possible position values for the switch.

unsafe fn isSequential(&self) -> bool

where Self: Sized + Message,

YESif the switch input can only transition to positions that are adjacent to the current position.

unsafe fn canWrap(&self) -> bool

where Self: Sized + Message,

Check if the position input value can “roll over” when reaching either of its bounds.

This will always be YESfor non-sequential switch inputs.

unsafe fn lastPositionTimestamp(&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 returned timestamp to determine the time (in seconds) between changes to the value.

unsafe fn lastPositionLatency(&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.
