Implementations

impl Pad

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

impl Pad

pub fn new(direction: PadDirection) -> Self

Creates a new Pad with the specified PadDirection.

An automatically generated name will be assigned.

Use Pad::builder() to get a PadBuilder and define options.

pub fn builder(direction: PadDirection) -> PadBuilder<Self>

Creates a PadBuilder with the specified PadDirection.

An automatically generated name will be assigned.

pub fn from_static_template(templ: &StaticPadTemplate) -> Self

Creates a new Pad from the StaticPadTemplate.

If the StaticPadTemplate has a specific name_template, i.e. if it’s not a wildcard-name containing %u, %s or %d, the Pad will automatically be named after the name_template.

Panics

Panics if the name_template is a wildcard-name.

Use Pad::builder_from_static_template() to get a PadBuilder and define options.

pub fn builder_from_static_template( templ: &StaticPadTemplate, ) -> PadBuilder<Self>

Creates a new PadBuilder from the StaticPadTemplate.

If the StaticPadTemplate has a specific name_template, i.e. if it’s not a wildcard-name containing %u, %s or %d, the Pad will automatically be named after the name_template.

Use PadBuilder::name or PadBuilder::maybe_name to specify a different name.

pub fn from_template(templ: &PadTemplate) -> Self

Creates a new Pad from the PadTemplate.

If the PadTemplate has a specific name_template, i.e. if it’s not a wildcard-name containing %u, %s or %d, the Pad will automatically be named after the name_template.

Panics

Panics if the name_template is a wildcard-name.

Use Pad::builder_from_template() to get a PadBuilder and define options.

pub fn builder_from_template(templ: &PadTemplate) -> PadBuilder<Self>

Creates a new PadBuilder from the PadTemplate.

If the PadTemplate has a specific name_template, i.e. if it’s not a wildcard-name containing %u, %s or %d, the Pad will automatically be named after the name_template.

Use PadBuilder::name or PadBuilder::maybe_name to specify a different name.

pub fn query_default<O: IsA<Pad>>( pad: &O, parent: Option<&impl IsA<Object>>, query: &mut QueryRef, ) -> bool

pub fn event_default<O: IsA<Pad>>( pad: &O, parent: Option<&impl IsA<Object>>, event: impl Into<Event>, ) -> bool

Trait Implementations

impl Clone for Pad

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 Pad

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

Formats the value using the given formatter.

impl HasParamSpec for Pad

type ParamSpec = ParamSpecObject

type SetValue = Pad

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for Pad

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<T: PadImpl> IsSubclassable<T> for Pad

fn class_init(klass: &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 Pad

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 + PartialOrd,

Restrict a value to a certain interval.

impl ParentClassIs for Pad

type Parent = Object

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

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

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

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

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 Pad

fn static_type() -> Type

Returns the type identifier of Self.
