Struct GestureSingle 

pub struct GestureSingle { /* private fields */ }

GestureSingle is a subclass of Gesture, optimized (although not restricted) for dealing with mouse and single-touch gestures. Under interaction, these gestures stick to the first interacting sequence, which is accessible through GestureSingleExt::current_sequence() while the gesture is being interacted with.

By default gestures react to both GDK_BUTTON_PRIMARY and touch events, GestureSingleExt::set_touch_only() can be used to change the touch behavior. Callers may also specify a different mouse button number to interact with through GestureSingleExt::set_button(), or react to any mouse button by setting 0. While the gesture is active, the button being currently pressed can be known through GestureSingleExt::current_button().

Properties

button

Mouse button number to listen to, or 0 to listen for any button.

Readable | Writable

exclusive

Whether the gesture is exclusive. Exclusive gestures only listen to pointer and pointer emulated events.

Readable | Writable

touch-only

Whether the gesture handles only touch events.

Readable | Writable

Gesture

n-points

The number of touch points that trigger recognition on this gesture,

Readable | Writable | Construct Only

window

If non-None, the gesture will only listen for events that happen on this gdk::Window, or a child of it.

Readable | Writable

EventController

propagation-phase

The propagation phase at which this controller will handle events.

Readable | Writable

widget

The widget receiving the GdkEvents that the controller will handle.

Implements

GestureSingleExt, GestureExt, EventControllerExt, [trait@glib::ObjectExt]

GLib type: GObject with reference counted clone semantics.

Implementations

impl GestureSingle

pub const NONE: Option<&'static GestureSingle> = None

Trait Implementations

impl Clone for GestureSingle

fn clone(&self) -> Self

Makes a clone of this shared reference.

This increments the strong reference count of the object. Dropping the object will decrement it again.

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

Performs copy-assignment from source.

impl Debug for GestureSingle

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

Formats the value using the given formatter.

impl Eq for GestureSingle

impl HasParamSpec for GestureSingle

type ParamSpec = ParamSpecObject

type SetValue = GestureSingle

Preferred value to be used as setter for the associated ParamSpec.

type BuilderFn = fn(&str) -> ParamSpecObjectBuilder<'_, GestureSingle>

fn param_spec_builder() -> Self::BuilderFn

impl Hash for GestureSingle

fn hash<H>(&self, state: &mut H)

where H: Hasher,

Hashes the memory address of this object.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl IsA<GestureSingle> for GestureSwipe

impl Ord for GestureSingle

fn cmp(&self, other: &Self) -> Ordering

Comparison for two GObjects.

Compares the memory addresses of the provided objects.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl ParentClassIs for GestureSingle

type Parent = Gesture

impl<OT: ObjectType> PartialEq<OT> for GestureSingle

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

Equality for two GObjects.

Two GObjects are equal if their memory addresses are equal.

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

Inequality operator !=.

impl<OT: ObjectType> PartialOrd<OT> for GestureSingle

fn partial_cmp(&self, other: &OT) -> Option<Ordering>

Partial comparison for two GObjects.

Compares the memory addresses of the provided objects.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl StaticType for GestureSingle

fn static_type() -> Type

Returns the type identifier of Self.
