Struct MacOSTopLevelHandle 

pub struct MacOSTopLevelHandle { /* private fields */ }

The platform handle of a top-level of this backend.

A handle obtained from ITopLevelImpl::handle of this backend can be downcast (through as_any) to this type, which implements IMacOSTopLevelPlatformHandle.

Trait Implementations

impl IMacOSTopLevelPlatformHandle for MacOSTopLevelHandle

fn ns_view(&self) -> isize

The NSView of the top level.

fn get_ns_view_retained(&self) -> isize

The NSView of the top level, retained: the caller releases it.

fn ns_window(&self) -> isize

The NSWindow of the top level.

fn get_ns_window_retained(&self) -> isize

The NSWindow of the top level, retained: the caller releases it.

impl IPlatformHandle for MacOSTopLevelHandle

fn handle(&self) -> isize

Gets the handle (a native pointer or identifier).

fn handle_descriptor(&self) -> Option<&str>

Gets an optional string that describes what handle represents.

fn as_any(&self) -> &dyn Any

Lets backends recover the concrete handle type.

fn equals(&self, other: &dyn IPlatformHandle) -> bool

Whether this handle is equal to other.

fn as_native_control_host_destroyable_control_handle( &self, ) -> Option<&dyn INativeControlHostDestroyableControlHandle>

The handle as the handle of a native control that can be destroyed, if it is one (C# handle as INativeControlHostDestroyableControlHandle). An implementation of that contract returns itself.
