Available on crate feature GCTouchedStateInput only.

An object conforming to GCTouchedStateInputrepresents the touched state of an element.

Some buttons feature capacitive touch capabilities, where the user can touch the button without pressing it. In such cases, a button can be touched without being pressed.

Provided Methods

unsafe fn touchedDidChangeHandler( &self, ) -> *mut DynBlock<dyn Fn(NonNull<ProtocolObject<dyn GCPhysicalInputElement>>, NonNull<ProtocolObject<dyn GCTouchedStateInput>>, Bool)>

where Self: Sized + Message,

Available on crate features GCPhysicalInputElement and block2 only.

Set this block if you want to be notified when the touched state changes.

unsafe fn setTouchedDidChangeHandler( &self, touched_did_change_handler: Option<&DynBlock<dyn Fn(NonNull<ProtocolObject<dyn GCPhysicalInputElement>>, NonNull<ProtocolObject<dyn GCTouchedStateInput>>, Bool)>>, )

where Self: Sized + Message,

Available on crate features GCPhysicalInputElement and block2 only.

Setter for touchedDidChangeHandler.

unsafe fn isTouched(&self) -> bool

where Self: Sized + Message,

Some buttons feature capacitive touch capabilities, where the user can touch the button without pressing it. In such cases, a button will be touched before it is pressed.

See: touchedDidChangeHandler

See: GCPressedStateInput

unsafe fn lastTouchedStateTimestamp(&self) -> NSTimeInterval

where Self: Sized + Message,

The timestamp of the last touched state change.

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 lastTouchedStateLatency(&self) -> NSTimeInterval

where Self: Sized + Message,

The interval (in seconds) between the timestamp of the last touched state change 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.
