pub fn upcast_ref(&self) -> &ParamSpec

impl ParamSpecDouble

pub fn default_value(&self) -> f64

impl ParamSpecDouble

pub fn minimum(&self) -> f64

impl ParamSpecDouble

pub fn new(
    name: &str,

impl ParamSpecDouble

pub fn builder<'a>(name: &'a str) -> ParamSpecDoubleBuilder<'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
