Struct gtk4::GestureLongPress

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

GestureLongPress is a Gesture for long presses.

This gesture is also known as “Press and Hold”.

When the timeout is exceeded, the gesture is triggering the signal::GestureLongPress::pressed signal.

If the touchpoint is lifted before the timeout passes, or if it drifts too far of the initial press point, the signal::GestureLongPress::cancelled signal will be emitted.

How long the timeout is before the ::pressed signal gets emitted is determined by the property::Settings::gtk-long-press-time setting. It can be modified by the property::GestureLongPress::delay-factor property.

Implementations

impl GestureLongPress

pub fn new() -> GestureLongPress

Returns a newly created Gesture that recognizes long presses.

Returns

a newly created GestureLongPress.

pub fn builder() -> GestureLongPressBuilder

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

This method returns an instance of GestureLongPressBuilder which can be used to create GestureLongPress objects.

pub fn delay_factor(&self) -> f64

Returns the delay factor.

Returns

the delay factor

pub fn set_delay_factor(&self, delay_factor: f64)

Applies the given delay factor.

The default long press time will be multiplied by this value. Valid values are in the range [0.5..2.0].

delay_factor

The delay factor to apply

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

Emitted whenever a press moved too far, or was released before signal::GestureLongPress::pressed happened.

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

Emitted whenever a press goes unmoved/unreleased longer than what the GTK defaults tell.

x

the X coordinate where the press happened, relative to the widget allocation

y

the Y coordinate where the press happened, relative to the widget allocation

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

Trait Implementations

impl Clone for GestureLongPress

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 GestureLongPress

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

Formats the value using the given formatter.

impl Default for GestureLongPress

fn default() -> Self

Returns the “default value” for a type.

impl Display for GestureLongPress

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

Formats the value using the given formatter.

impl Hash for GestureLongPress

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 GestureLongPress

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.

impl ParentClassIs for GestureLongPress

type Parent = GestureSingle

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

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.

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 GestureLongPress

fn static_type() -> Type
