Provided Methods

fn default_with_attached_qobject() -> Rc<RefCell<Self>>

Create a new default-initialized instance of this type and attach the required [QObject]. This enables use of this instance in QML. Instances created with this function must remain at its original heap location and must not be moved out of Rc<RefCell<T>>.

fn attach_qobject(instance: &Rc<RefCell<Self>>)

Create and attach a dedicated [QObject] to the instance. The instance must remain at its original heap location and must not be moved out of Rc<RefCell<T>>.

fn detach_qobject(&self)

Detach and remove the dedicated [QObject] from the specified object. This function is intended to be called during the Drop implementation of this type.

fn as_qvariant(&self) -> QVariant

Return a QVariant containing a pointer to this object.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
