Struct druid::piet::cairo::glib::object::InterfaceRef

pub struct InterfaceRef<'a, T>(_, _, _)
where
         T: IsInterface;

Reference to a class struct of type T.

Methods from Deref<Target = Interface<T>>

pub fn type_(&self) -> Type

Get the type id for this interface.

This is equivalent to T::static_type().

pub fn instance_type(&self) -> Type

Get the type id for the instance type of this interface.

This is not equivalent to T::static_type() but is the type id of the type this specific interface belongs to.

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

Gets the parent interface struct, if any.

This returns the parent interface if a parent type of the instance type also implements the interface.

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

Check if this interface has a property property_name of the given type_.

If no type is provided then only the existence of the property is checked.

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

Get the type of the property property_name of this interface.

This returns None if the property does not exist.

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

Get the ParamSpec of the property property_name of this interface.

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

Return all ParamSpec of the properties of this interface.
