Trait QmlObject 

pub trait QmlObject: QObjectHolder {
    // Provided methods
    fn default_with_attached_qobject() -> Rc<RefCell<Self>>
       where Self: Default { ... }
    fn attach_qobject(instance: &Rc<RefCell<Self>>) { ... }
    fn detach_qobject(&self) { ... }
    fn get_qml_method_invoker(&self) -> QmlMethodInvoker { ... }
}

Provided Methods

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

where Self: Default,

Creates a default-initialized instance and attaches its [QObject] eagerly.

The returned Rc<RefCell<Self>> is an ordinary handle, shared with QML. Droping the handle does not drop the instance if it is in use by QML or until the garbage collection delete the QML instance.

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

Attaches a dedicated [QObject] to an existing instance, enabling its use in QML.

fn detach_qobject(&self)

Detaches and deletes the dedicated [QObject] of this instance.

The instance continues as a plain Rust value and heals with a fresh [QObject] on its next exposure to QML.

fn get_qml_method_invoker(&self) -> QmlMethodInvoker

Returns a QmlMethodInvoker that can invoke methods on the underlying QObject from any thread.

Example

let backend = Backend::default_with_attached_qobject();
let invoker = backend.borrow().get_qml_method_invoker();
invoker.invoke_method("dataReady");

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.
