#[repr(transparent)]
pub struct QObjectPinned<'pin, T: QObject + ?Sized + 'pin>(_);

Expand description

A reference to a RefCell, where T is a QObject, which does not move in memory

Implementations

source

impl<'pin, T: QObject + ?Sized + 'pin> QObjectPinned<'pin, T>

source

pub fn borrow(&self) -> &T

Borrow the object

source

pub unsafe fn new(inner: &'pin RefCell<T>) -> Self

Internal function used from the code generated by the QObject derive macro. Unsafe because one must ensure it does not move in memory.

source

impl<'pin, T: QObject + 'pin> QObjectPinned<'pin, T>

source

pub fn get_or_create_cpp_object(self) -> *mut c_void

Get the pointer ot the C++ Object, or crate it if it was not yet created
