Struct gtk4::ScaleButton

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

ScaleButton provides a button which pops up a scale widget.

This kind of widget is commonly used for volume controls in multimedia applications, and GTK provides a VolumeButton subclass that is tailored for this use case.

CSS nodes

ScaleButton has a single CSS node with name button. To differentiate it from a plain Button, it gets the .scale style class.

Implementations

impl ScaleButton

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

pub fn new(min: f64, max: f64, step: f64, icons: &[&str]) -> ScaleButton

Creates a ScaleButton.

The new scale button has a range between @min and @max, with a stepping of @step.

min

the minimum value of the scale (usually 0)

max

the maximum value of the scale (usually 100)

step

the stepping of value when a scroll-wheel event, or up/down arrow event occurs (usually 2)

icons

a None-terminated array of icon names, or None if you want to set the list later with gtk_scale_button_set_icons()

Returns

a new ScaleButton

pub fn builder() -> ScaleButtonBuilder

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

This method returns an instance of ScaleButtonBuilder which can be used to create ScaleButton objects.

Trait Implementations

impl Clone for ScaleButton

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 ScaleButton

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

Formats the value using the given formatter.

impl Default for ScaleButton

fn default() -> Self

Returns the “default value” for a type.

impl Display for ScaleButton

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

Formats the value using the given formatter.

impl Hash for ScaleButton

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<T: ScaleButtonImpl> IsSubclassable<T> for ScaleButton

fn class_init(class: &mut Class<Self>)

Override the virtual methods of this class for the given subclass and do other class initialization.

fn instance_init(instance: &mut InitializingObject<T>)

Instance specific initialization.

impl Ord for ScaleButton

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 ScaleButton

type Parent = Widget

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

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 ScaleButton

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 ScaleButton

fn static_type() -> Type

Returns the type identifier of Self.
