Struct qmetaobject::QPointer

pub struct QPointer<T: QObject + ?Sized>(_, _);

A Wrapper around a QPointer

Implementations

impl<T: QObject + ?Sized> QPointer<T>

pub fn cpp_ptr(&self) -> *mut c_void

Returns a pointer to the cpp object (null if it was deleted)

pub fn as_ref(&self) -> Option<&T>

Returns a reference to the QObject, or None if it was deleted

pub fn is_null(&self) -> bool

Returns true if the object was default constructed or constructed with an object which is now deleted

impl<T: QObject> QPointer<T>

pub fn as_pinned(&self) -> Option<QObjectPinned<'_, T>>

Returns a pinned reference to the QObject, or None if it was deleted

Trait Implementations

impl<T: QObject + ?Sized> Clone for QPointer<T>

fn clone(&self) -> Self

Returns a copy of the value.

pub fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: QObject> Default for QPointer<T>

fn default() -> Self

Returns the “default value” for a type.

impl<'a, T: QObject + ?Sized> From<&'a T> for QPointer<T>

fn from(obj: &'a T) -> Self

Creates a QPointer from a reference to a QObject. The corresponding C++ object must have already been created.

    T: QObject,
