Struct WindowHandle

Source

pub struct WindowHandle { /* private fields */ }

Expand description

A live secondary window (docs/windows.md). Cheap to clone; inert after close.

Implementations§

Source §

impl WindowHandle

Source

pub fn close(&self)

Close the window. Asynchronous: the platform (or the cover’s hide transition) confirms, then the content is disposed and on_close callbacks run. Idempotent.

Source

pub fn focus(&self)

Bring the window to front and make it key. No-op on the cover tier (the cover is already frontmost in the primary window) and while a Pending open is in flight.

Source

pub fn set_title(&self, title: &str)

Retitle the window. Applies to live native windows; a Pending window picks the new title up at completion; the cover tier has no title bar (no-op).

Source

pub fn is_open(&self) -> bool

Whether the window is still open (its record exists — a Pending open counts).

Source

pub fn on_close(&self, f: impl Fn() + 'static)

Run f after the window has closed and its content is disposed — any close path (title-bar, platform gesture, WindowHandle::close). No-op if already closed.
