Implementations

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 + IsA<T>>(&self) -> Option<&Class<U>>

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 + IsA<T>>(&mut self) -> Option<&mut Class<U>>

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.

Trait Implementations

impl<T: IsClass> AsRef<<T as ObjectType>::GlibClassType> for Class<T>

fn as_ref(&self) -> &T::GlibClassType

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

impl<T: ObjectType + IsClass> ObjectClassExt for Class<T>

fn has_property(&self, property_name: &str, type_: Option<Type>) -> bool

fn property_type(&self, property_name: &str) -> Option<Type>

Get the type of the property property_name of this object class.

fn find_property(&self, property_name: &str) -> Option<ParamSpec>

Get the ParamSpec of the property property_name of this object class.

fn list_properties(&self) -> PtrSlice<ParamSpec>
