Struct glib::ParamSpecOverride

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

Implementations

impl ParamSpecOverride

pub fn upcast(self) -> ParamSpec

pub fn upcast_ref(&self) -> &ParamSpec

impl ParamSpecOverride

pub fn new(name: &str, overridden: &ParamSpec) -> ParamSpec

pub fn for_interface<T: IsA<Object> + IsInterface>(name: &str) -> ParamSpec

Similar to ParamSpecOverride::new but specific for an interface.

Examples

let pspec = ParamSpecOverride::for_interface::<gtk::Scrollable>("vadjustment");

Panics

If the property name doesn’t exist in the interface.

pub fn for_class<T: IsA<Object> + IsClass>(name: &str) -> ParamSpec

Similar to ParamSpecOverride::new but specific for a class.

Examples

let pspec = ParamSpecOverride::for_class::<gtk::Button>("label");

Panics

If the property name doesn’t exist in the class.

pub fn overridden(&self) -> ParamSpec

pub fn builder<'a>( name: &'a str, overridden: &'a ParamSpec ) -> ParamSpecOverrideBuilder<'a>

Methods from Deref<Target = ParamSpec>

pub fn downcast_ref<T: ParamSpecType>(&self) -> Option<&T>

pub fn type_(&self) -> Type

pub fn value_type(&self) -> Type

pub fn owner_type(&self) -> Type

pub fn flags(&self) -> ParamFlags

pub fn blurb(&self) -> &str

Get the short description of a ParamSpec.

Returns

the short description of self.

pub fn default_value(&self) -> &Value

Gets the default value of self as a pointer to a Value.

The Value will remain valid for the life of self.

Returns

a pointer to a Value which must not be modified

pub fn name<'a>(&self) -> &'a str

Get the name of a ParamSpec.

The name is always an “interned” string (as per g_intern_string()). This allows for pointer-value comparisons.

Returns

the name of self.

pub fn name_quark(&self) -> Quark

Gets the GQuark for the name.

Returns

the GQuark for self->name.

pub fn nick(&self) -> &str

Get the nickname of a ParamSpec.

Returns

the nickname of self.

pub fn redirect_target(&self) -> Option<ParamSpec>

If the paramspec redirects operations to another paramspec, returns that paramspec. Redirect is used typically for providing a new implementation of a property in a derived type while preserving all the properties from the parent type. Redirection is established by creating a property of type ParamSpecOverride. See g_object_class_override_property() for an example of the use of this capability.

Returns

paramspec to which requests on this paramspec should be redirected, or None if none.

Trait Implementations

impl AsRef<ParamSpec> for ParamSpecOverride

fn as_ref(&self) -> &ParamSpec

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for ParamSpecOverride

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 ParamSpecOverride

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

Formats the value using the given formatter.

impl Deref for ParamSpecOverride

type Target = ParamSpec

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl Hash for ParamSpecOverride

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

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 ParamSpecOverride

fn cmp(&self, other: &ParamSpecOverride) -> 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 PartialEq<ParamSpecOverride> for ParamSpecOverride

fn eq(&self, other: &ParamSpecOverride) -> 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 PartialOrd<ParamSpecOverride> for ParamSpecOverride

fn partial_cmp(&self, other: &ParamSpecOverride) -> 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 ParamSpecOverride

fn static_type() -> Type

Returns the type identifier of Self.
