Trait that is implemented by the QObject custom derive macro

Do not implement this trait yourself, use #[derive(QObject)].

The method of this trait fits into two categories: the ones that are re-implemented by the custom derive, and the ones that are used by this macro and need to be implemented by other QObject-like trait which you use in the qt_base_class! macro.

Required Methods

fn meta_object(&self) -> *const QMetaObject

Returns a pointer to a meta object

fn static_meta_object() -> *const QMetaObject

where Self: Sized,

Returns a pointer to a meta object

fn get_cpp_object(&self) -> *mut c_void

return a C++ pointer to the QObject* (can be null if not yet initialized)

unsafe fn cpp_construct(pined: &RefCell<Self>) -> *mut c_void

where Self: Sized,

Construct the C++ Object.

Note, once this function is called, the object must not be moved in memory.

unsafe fn qml_construct( pined: &RefCell<Self>, mem: *mut c_void, extra_destruct: extern "C" fn(_: *mut c_void) )

where Self: Sized,

Construct the C++ Object, suitable for callbacks to construct QML objects.

fn cpp_size() -> usize

where Self: Sized,

Return the size of the C++ object

unsafe fn get_from_cpp<'a>(p: *mut c_void) -> QObjectPinned<'a, Self>

where Self: Sized,

Return a rust object belonging to a C++ object

Provided Methods

fn get_object_description() -> &'static QObjectDescriptor

where Self: Sized,

Returns a QObjectDescriptor for this type

Implementations

impl dyn QObject

pub unsafe fn as_qvariant(&self) -> QVariant

Creates a C++ object and construct a QVariant containing a pointer to it.

The cpp_construct function must already have been called.

FIXME: should probably not be used. Prefer using a QmlEngine::new_qobject. QVariant is unsafe as it does not manage life time

pub fn destroyed_signal() -> Signal<fn()>

See Qt documentation for QObject::destroyed

pub fn set_object_name(&self, name: QString)

See Qt documentation for QObject::setObjectName

pub fn object_name_changed_signal() -> Signal<fn(_: QString)>

See Qt documentation for QObject::objectNameChanged
