Implementations§

source§

impl<'a> KeyEvent<'a>

source

pub fn source(&self) -> Source

Get the source of the event.

source

pub fn class(&self) -> Class

Get the class of the event source.

source

pub fn device_id(&self) -> i32

Get the device id associated with the event.

source

pub fn action(&self) -> KeyAction

Returns the key action associated with the event.

See the KeyEvent docs

source

pub fn down_time(&self) -> i64

Returns the last time the key was pressed. This is on the scale of java.lang.System.nanoTime(), which has nanosecond precision, but no defined start time.

See the NDK docs

source

pub fn event_time(&self) -> i64

Returns the time this event occured. This is on the scale of java.lang.System.nanoTime(), which has nanosecond precision, but no defined start time.

See the NDK docs

source

pub fn key_code(&self) -> Keycode

Returns the keycode associated with this key event

See the NDK docs

source

pub fn repeat_count(&self) -> i32

Returns the number of repeats of a key.

See the NDK docs

source

pub fn scan_code(&self) -> i32

Returns the hardware keycode of a key. This varies from device to device.

See the NDK docs
