Implementations§

source§

impl AndroidKeyFlag

source

pub const SOFT_KEYBOARD: Self = _

This mask is set if the key event was generated by a software keyboard.

source

pub const KEEP_TOUCH_MODE: Self = _

This mask is set if we don’t want the key event to cause us to leave touch mode.

source

pub const FROM_SYSTEM: Self = _

This mask is set if an event was known to come from a trusted part of the system. That is, the event is known to come from the user, and could not have been spoofed by a third party component.

source

pub const EDITOR_ACTION: Self = _

This mask is used for compatibility, to identify enter keys that are coming from an IME whose enter key has been auto-labelled “next” or “done”. This allows TextView to dispatch these as normal enter keys for old applications, but still do the appropriate action when receiving them.

source

pub const CANCELED: Self = _

When associated with up key events, this indicates that the key press has been canceled. Typically this is used with virtual touch screen keys, where the user can slide from the virtual key area on to the display: in that case, the application will receive a canceled up event and should not perform the action normally associated with the key. Note that for this to work, the application can not perform an action for a key until it receives an up or the long press timeout has expired.

source

pub const VIRTUAL_HARD_KEY: Self = _

This key event was generated by a virtual (on-screen) hard key area. Typically this is an area of the touchscreen, outside of the regular display, dedicated to “hardware” buttons.

source

pub const LONG_PRESS: Self = _

This flag is set for the first key repeat that occurs after the long press timeout.

source

pub const CANCELED_LONG_PRESS: Self = _

Set when a key event has AndroidKeyFlag::CANCELED set because a long press action was executed while it was down.

source

pub const TRACKING: Self = _

Set for ACTION_UP when this event’s key value is still being tracked from its initial down. That is, somebody requested that tracking started on the key down and a long press has not caused the tracking to be canceled.

source

pub const FALLBACK: Self = _

Set when a key event has been synthesized to implement default behavior for an event that the application did not handle. Fallback key events are generated by unhandled trackball motions (to emulate a directional keypad) and by certain unhandled key presses that are declared in the key map (such as special function numeric keypad keys when numlock is off).

source

pub const PREDISPATCH: Self = _

Signifies that the key is being predispatched.

source

pub const START_TRACKING: Self = _

Private control to determine when an app is tracking a key sequence.

source

pub const TAINTED: Self = _

Private flag that indicates when the system has detected that this key event may be inconsistent with respect to the sequence of previously delivered key events, such as when a key up event is sent but the key was not down.

source

pub const fn all() -> Self

Get a flags value with all known bits set.

Convert from a bits value.

This method will return None if any unknown bits are set.

Convert from a bits value exactly.

source

pub fn from_name(name: &str) -> Option<Self>

source

pub fn remove(&mut self, other: Self)

The intersection of a source flags value with the complement of a target flags value (&!).

The bitwise exclusive-or (^) of the bits in two flags values.

source

pub fn set(&mut self, other: Self, value: bool)

The bitwise or (|) of the bits in two flags values.

source

pub const fn difference(self, other: Self) -> Self

The intersection of a source flags value with the complement of a target flags value (&!).

This method is not equivalent to self & !other when other has unknown bits set. difference won’t truncate other, but the ! operator will.

The bitwise exclusive-or (^) of the bits in two flags values.

source

pub const fn complement(self) -> Self

The bitwise negation (!) of the bits in a flags value, truncating the result.

source§

impl AndroidKeyFlag

source

pub const fn iter(&self) -> Iter<AndroidKeyFlag>

Yield a set of contained flags values.

Each yielded flags value will correspond to a defined named flag. Any unknown bits will be yielded together as a final flags value.

source

pub const fn iter_names(&self) -> IterNames<AndroidKeyFlag>

Yield a set of contained named flags values.

This method is like iter, except only yields bits in contained named flags. Any unknown bits, or bits not corresponding to a contained flag will not be yielded.
