Struct gtk4::GestureClick

#[repr(transparent)]
pub struct GestureClick { /* private fields */ }

GestureClick is a Gesture implementation for clicks.

It is able to recognize multiple clicks on a nearby zone, which can be listened for through the signal::GestureClick::pressed signal. Whenever time or distance between clicks exceed the GTK defaults, signal::GestureClick::stopped is emitted, and the click counter is reset.

Implementations

impl GestureClick

pub fn new() -> GestureClick

Returns a newly created Gesture that recognizes single and multiple presses.

Returns

a newly created GestureClick

pub fn builder() -> GestureClickBuilder

Creates a new builder-pattern struct instance to construct GestureClick objects.

This method returns an instance of GestureClickBuilder which can be used to create GestureClick objects.

pub fn connect_pressed<F: Fn(&Self, i32, f64, f64) + 'static>( &self, f: F ) -> SignalHandlerId

Emitted whenever a button or touch press happens.

n_press

how many touch/button presses happened with this one

x

The X coordinate, in widget allocation coordinates

y

The Y coordinate, in widget allocation coordinates

pub fn connect_released<F: Fn(&Self, i32, f64, f64) + 'static>( &self, f: F ) -> SignalHandlerId

Emitted when a button or touch is released.

@n_press will report the number of press that is paired to this event, note that signal::GestureClick::stopped may have been emitted between the press and its release, @n_press will only start over at the next press.

n_press

number of press that is paired with this release

x

The X coordinate, in widget allocation coordinates

y

The Y coordinate, in widget allocation coordinates

pub fn connect_stopped<F: Fn(&Self) + 'static>(&self, f: F) -> SignalHandlerId

Emitted whenever any time/distance threshold has been exceeded.

pub fn connect_unpaired_release<F: Fn(&Self, f64, f64, u32, Option<&EventSequence>) + 'static>( &self, f: F ) -> SignalHandlerId

Emitted whenever the gesture receives a release event that had no previous corresponding press.

Due to implicit grabs, this can only happen on situations where input is grabbed elsewhere mid-press or the pressed widget voluntarily relinquishes its implicit grab.

x

X coordinate of the event

y

Y coordinate of the event

button

Button being released

sequence

Sequence being released

Trait Implementations

impl Clone for GestureClick

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for GestureClick

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

Formats the value using the given formatter.

impl Default for GestureClick

fn default() -> Self

Returns the “default value” for a type.

impl Display for GestureClick

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

Formats the value using the given formatter.

impl Hash for GestureClick

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

Feeds this value into the given Hasher.

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 Ord for GestureClick

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Selfwhere Self: Sized + PartialOrd<Self>,

Restrict a value to a certain interval.

impl ParentClassIs for GestureClick

type Parent = GestureSingle

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

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

This method tests for self and other values to be equal, and is used by ==.

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

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

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

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

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl StaticType for GestureClick

fn static_type() -> Type

Returns the type identifier of Self.
