Struct glib::object::Class

#[repr(transparent)]
pub struct Class<T: IsClass>(_);

Class struct of type T.

Implementations

impl Class<Object>

pub fn has_property<'a, N: Into<&'a str>>(
    &self,
    property_name: N,
    type_: Option<Type>
) -> bool

pub fn property_type<'a, N: Into<&'a str>>(
    &self,
    property_name: N
) -> Option<Type>

pub fn find_property<'a, N: Into<&'a str>>(
    &self,
    property_name: N
) -> Option<ParamSpec>

pub fn list_properties(&self) -> Vec<ParamSpec>

impl<T: IsClass> Class<T>

pub fn type_(&self) -> Type

Get the type id for this class.

This is not equivalent to T::static_type() but is the type of the subclass of T where this class belongs to.

pub fn upcast_ref<U: IsClass>(&self) -> &Class<U> where
    T: IsA<U>, 

Casts this class to a reference to a parent type’s class.

pub fn upcast_ref_mut<U: IsClass>(&mut self) -> &mut Class<U> where
    T: IsA<U>, 

Casts this class to a mutable reference to a parent type’s class.

pub fn downcast_ref<U: IsClass>(&self) -> Option<&Class<U>> where
    U: IsA<T>, 

Casts this class to a reference to a child type’s class or fails if this class is not implementing the child class.

pub fn downcast_ref_mut<U: IsClass>(&mut self) -> Option<&mut Class<U>> where
    U: IsA<T>, 

Casts this class to a mutable reference to a child type’s class or fails if this class is not implementing the child class.

pub fn from_type(type_: Type) -> Option<ClassRef<'static, T>>

Gets the class struct for Self of type_.

This will return None if type_ is not a subclass of Self.

pub fn parent(&self) -> Option<ClassRef<'_, T>>

Gets the parent class struct, if any.
