Struct gtk4::ParamSpecExpression

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

A GParamSpec for properties holding a Expression.

Implementations

impl ParamSpecExpression

pub fn as_ptr(&self) -> *mut GtkParamSpecExpression

Return the inner pointer to the underlying C value.

impl ParamSpecExpression

pub fn new(name: &str, nick: &str, blurb: &str, flags: ParamFlags) -> ParamSpec

pub fn builder(name: &str) -> ParamSpecExpressionBuilder<'_>

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

This method returns an instance of ParamSpecExpressionBuilder which can be used to create ParamSpecExpression objects.

pub fn upcast(self) -> ParamSpec

pub fn upcast_ref(&self) -> &ParamSpec

Methods from Deref<Target = ParamSpec>

pub fn as_ptr(&self) -> *mut GParamSpec

Return the inner pointer to the underlying C value.

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

pub fn type_(&self) -> Type

pub fn value_type(&self) -> Type

pub fn value_is_valid(&self, value: &Value) -> bool

Available on crate feature v2_74 only.

pub fn owner_type(&self) -> Type

pub fn flags(&self) -> ParamFlags

pub fn blurb(&self) -> Option<&str>

pub fn default_value(&self) -> &Value

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

pub fn name_quark(&self) -> Quark

pub fn nick(&self) -> &str

Returns the nickname of this ParamSpec.

If this ParamSpec does not have a nickname, the nickname of its redirect target is returned if it has one. Otherwise, self.name() is returned.

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