Struct Adapter

pub struct Adapter { /* private fields */ }

Implementations

impl Adapter

pub unsafe fn new( view: *mut c_void, is_view_focused: bool, action_handler: impl 'static + ActionHandler, ) -> Self

Create a new macOS adapter. This function must be called on the main thread.

The action handler will always be called on the main thread.

Safety

view must be a valid, unreleased pointer to an NSView.

pub fn update_if_active( &mut self, update_factory: impl FnOnce() -> TreeUpdate, ) -> Option<QueuedEvents>

If and only if the tree has been initialized, call the provided function and apply the resulting update. Note: If the caller’s implementation of ActivationHandler::request_initial_tree initially returned None, the TreeUpdate returned by the provided function must contain a full tree.

If a QueuedEvents instance is returned, the caller must call QueuedEvents::raise on it.

pub fn update_view_focus_state( &mut self, is_focused: bool, ) -> Option<QueuedEvents>

Update the tree state based on whether the window is focused.

If a QueuedEvents instance is returned, the caller must call QueuedEvents::raise on it.

pub fn view_children<H: ActivationHandler + ?Sized>( &mut self, activation_handler: &mut H, ) -> *mut NSArray<NSObject>

pub fn focus<H: ActivationHandler + ?Sized>( &mut self, activation_handler: &mut H, ) -> *mut NSObject

pub fn hit_test<H: ActivationHandler + ?Sized>( &mut self, point: NSPoint, activation_handler: &mut H, ) -> *mut NSObject
