Struct Window 

pub struct Window { /* private fields */ }

A window with a layer container for adding sublayers.

Implementations

impl Window

pub fn container(&self) -> &CALayer

Get the container layer.

Add your layers as sublayers of this container.

pub fn size(&self) -> (f64, f64)

Get the window size in points.

pub fn ns_window(&self) -> &NSWindow

Get the underlying NSWindow.

pub fn window_id(&self) -> u64

Returns the CGWindowID for this window.

This is useful for screen recording with t-rec’s HeadlessRecorder.

Example

use core_animation::prelude::*;
use t_rec::HeadlessRecorder;

let window = WindowBuilder::new()
    .title("Demo")
    .size(400.0, 300.0)
    .build();

let mut recorder = HeadlessRecorder::builder()
    .window_id(window.window_id())
    .fps(30)
    .output_gif("demo.gif")
    .build()?;

pub fn show(&self)

Show the window and bring it to the front.

If the window was created with .non_activating(), it will appear without stealing focus from the currently active application.

pub fn show_for(&self, duration: Duration)

Show the window for a specified duration, then hide it.

This shows the window, processes events for the given duration, and then hides the window before returning.

Example

use core_animation::prelude::*;

window.show_for(5.seconds());
window.show_for(500.millis());
window.show_for(1.5.seconds());

pub fn hide(&self)

Hide the window.

The window is removed from the screen but not destroyed. It can be shown again with show().

This method runs a brief event loop tick after ordering out to ensure the hide takes effect immediately, which is important when called from within another run loop (like t-rec’s presenter).

pub fn close(&self)

Close and release the window.

After calling this, the window should not be used again. Runs an event loop tick to ensure the close takes effect immediately.

pub fn is_visible(&self) -> bool

Returns whether the window is currently visible.

pub fn run_loop_tick(&self)

Run a single iteration of the event loop.

This processes pending events and returns immediately. Useful for custom animation loops.

pub fn run(&self)

Run the event loop indefinitely until the window is closed.
