Implementations

impl GhostPad

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

impl GhostPad

pub fn activate_mode_default<P: IsA<GhostPad>>( pad: &P, parent: Option<&impl IsA<Object>>, mode: PadMode, active: bool, ) -> Result<(), BoolError>

pub fn internal_activate_mode_default<P: IsA<GhostPad>>( pad: &P, parent: Option<&impl IsA<Object>>, mode: PadMode, active: bool, ) -> Result<(), BoolError>

pub fn new(direction: PadDirection) -> Self

Creates a new GhostPad with an automatically generated name.

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

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

Creates a PadBuilder for a PadBuilder with an automatically generated name.

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

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

Creates a new GhostPad 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 GhostPad will automatically be named after the name_template.

Panics

Panics if the name_template is a wildcard-name.

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

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

Creates a new PadBuilder for a GhostPad 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 GhostPad 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 GhostPad 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 GhostPad will automatically be named after the name_template.

Panics

Panics if the name_template is a wildcard-name.

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

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

Creates a new PadBuilder for a GhostPad 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 GhostPad will automatically be named after the name_template.

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

pub fn with_target<P: IsA<Pad> + IsA<Object>>( target: &P, ) -> Result<Self, BoolError>

Creates a new GhostPad from the specified target Pad.

The GhostPad will automatically be named after the target name.

Use GhostPad::builder_with_target() to get a PadBuilder and define options.

pub fn builder_with_target<P: IsA<Pad> + IsA<Object>>( target: &P, ) -> Result<PadBuilder<Self>, BoolError>

Creates a new PadBuilder for a GhostPad from the specified target Pad.

The GhostPad will automatically be named after the target name.

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

pub fn from_template_with_target<P: IsA<Pad> + IsA<Object>>( templ: &PadTemplate, target: &P, ) -> Result<Self, BoolError>

Creates a new GhostPad from the PadTemplate with the specified target Pad.

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

If the name_template is a wildcard-name, then the target name is used, if it is compatible. Otherwise, a specific name must be provided using PadBuilder::name or PadBuilder::maybe_name.

pub fn builder_from_template_with_target<P: IsA<Pad> + IsA<Object>>( templ: &PadTemplate, target: &P, ) -> Result<PadBuilder<Self>, BoolError>

Creates a new PadBuilder for a GhostPad from the PadTemplate with the specified target Pad.

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

If the name_template is a wildcard-name, then the target name is used, if it is compatible. Otherwise, a specific name must be provided using PadBuilder::name or PadBuilder::maybe_name.

Trait Implementations

impl Clone for GhostPad

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 GhostPad

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

Formats the value using the given formatter.

impl HasParamSpec for GhostPad

type ParamSpec = ParamSpecObject

type SetValue = GhostPad

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

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

fn param_spec_builder() -> Self::BuilderFn

impl Hash for GhostPad

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: GhostPadImpl> IsSubclassable<T> for GhostPad

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 GhostPad

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.
