Struct ResultFlag

pub struct ResultFlag(/* private fields */);

This enum describes the result of the current event filtering step in a gesture recognizer state machine.

C++ enum: QGestureRecognizer::ResultFlag.

C++ documentation:

This enum describes the result of the current event filtering step in a gesture recognizer state machine.

The result consists of a state value (one of Ignore, MayBeGesture, TriggerGesture, FinishGesture, CancelGesture) and an optional hint (ConsumeEventHint).

The Result type is a typedef for QFlags<ResultFlag>. It stores an OR combination of ResultFlag values.

See also QGestureRecognizer::recognize().

Implementations

impl ResultFlag

pub fn to_int(&self) -> c_int

impl ResultFlag

pub const Ignore: ResultFlag

The event does not change the state of the recognizer. (C++ enum variant: Ignore = 1)

pub const MayBeGesture: ResultFlag

The event changed the internal state of the recognizer, but it isn’t clear yet if it is a gesture or not. The recognizer needs to filter more events to decide. Gesture recognizers in the MayBeGesture state may be reset automatically if they take too long to recognize gestures. (C++ enum variant: MayBeGesture = 2)

pub const TriggerGesture: ResultFlag

The gesture has been triggered and the appropriate QGesture object will be delivered to the target as a part of a QGestureEvent. (C++ enum variant: TriggerGesture = 4)

pub const FinishGesture: ResultFlag

The gesture has been finished successfully and the appropriate QGesture object will be delivered to the target as a part of a QGestureEvent. (C++ enum variant: FinishGesture = 8)

pub const CancelGesture: ResultFlag

The event made it clear that it is not a gesture. If the gesture recognizer was in GestureTriggered state before, then the gesture is canceled and the appropriate QGesture object will be delivered to the target as a part of a QGestureEvent. (C++ enum variant: CancelGesture = 16)

pub const ResultStateMask: ResultFlag

C++ enum variant: ResultState_Mask = 255

pub const ConsumeEventHint: ResultFlag

This hint specifies that the gesture framework should consume the filtered event and not deliver it to the receiver. (C++ enum variant: ConsumeEventHint = 256)

pub const ResultHintMask: ResultFlag

C++ enum variant: ResultHint_Mask = 65280

Trait Implementations

impl<T: Into<QFlags<ResultFlag>>> BitOr<T> for ResultFlag

type Output = QFlags<ResultFlag>

The resulting type after applying the | operator.

fn bitor(self, rhs: T) -> QFlags<ResultFlag>

Performs the | operation.

impl Clone for ResultFlag

fn clone(&self) -> ResultFlag

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ResultFlag

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<ResultFlag> for QFlags<ResultFlag>

fn from(value: ResultFlag) -> Self

Converts to this type from the input type.

impl From<ResultFlag> for c_int

fn from(value: ResultFlag) -> Self

Converts to this type from the input type.

impl From<i32> for ResultFlag

fn from(value: c_int) -> Self

Converts to this type from the input type.

impl PartialEq for ResultFlag

fn eq(&self, other: &ResultFlag) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
