Struct TitleBarHostCallbacks 

pub struct TitleBarHostCallbacks {
    pub request_close: Rc<dyn Fn()>,
    pub post_external: Rc<dyn Fn(Box<dyn Any + Send>)>,
    pub teksilo_id: TeksiloWindowId,
}

Callbacks the window manager hands to a platform host at construction time. Hosts invoke these for operations that must go through the event loop:

• request_close: winit 0.30 has no synchronous Window::request_close, so the host posts a CloseWindowRequest and teksilo-app routes it to WindowManager::queue_close.
• post_external: the Windows backend forwards WM_NCLBUTTONUP / WM_NCMOUSEMOVE over its custom title-bar buttons as TitleBarSyntheticEvent / TitleBarHoverEvent payloads through the same AppEvent::External arm. The closure abstracts the posting mechanism (a winit EventLoopProxy in production) so teksilo-core stays winit-free.
• teksilo_id: the host’s window id, copied into the synthetic payloads so the dispatcher knows which window to address.

Fields

request_close: Rc<dyn Fn()>

post_external: Rc<dyn Fn(Box<dyn Any + Send>)>

Post a Box<dyn Any + Send> payload back to the application event loop. Currently used by the Windows backend for TitleBarSyntheticEvent and TitleBarHoverEvent. Wayland and macOS construct hosts that never call this.

teksilo_id: TeksiloWindowId

teksilo-side window id. The Windows backend stamps this into every synthetic payload it posts so the app dispatcher can route into the right WidgetTree.

Implementations

impl TitleBarHostCallbacks

pub fn noop() -> Self

Callbacks that do nothing. Useful for tests and for platform stubs that never construct a host (a headless build, or X11 with no EWMH-capable window manager).

Trait Implementations

impl Clone for TitleBarHostCallbacks

fn clone(&self) -> TitleBarHostCallbacks

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TitleBarHostCallbacks

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
