Struct WindowManager 

pub struct WindowManager<R: Renderer> { /* private fields */ }

Owns all windows. The OS adapter calls methods on this.

Generic over R: Renderer — the renderer creates per-window GPU surfaces from raw window handles. The OS adapter provides the handles, the renderer creates the surfaces, and this manager owns the pipelines.

Implementations

impl<R: Renderer> WindowManager<R>

pub fn new(renderer: R) -> Self

pub fn create_window<W, F>( &mut self, window_handle: &W, config: WindowCreateConfig, view_init: F, ) -> Result<(), CreateWindowError>

where W: HasWindowHandle + HasDisplayHandle, F: FnOnce(&ViewContext) + Send + 'static,

Create a window: create GPU surface from handle, spawn view + render threads.

The OS adapter creates the OS window and passes the raw handle here. This manager uses the renderer to create the surface, then spawns the pipeline (render + view threads). The OS adapter keeps the window handle alive until after close_window returns.

pub fn close_window(&mut self, id: WindowId)

pub fn has_windows(&self) -> bool

pub fn shutdown_all(&mut self)

pub fn scale_factor(&self, id: WindowId) -> Option<f64>

Scale factor for a window — used by the OS adapter for pixel delta conversion.

pub fn on_resize(&mut self, id: WindowId, width: u32, height: u32)

pub fn on_scale_factor_changed( &mut self, id: WindowId, scale_factor: f64, refresh_rate_millihertz: Option<u32>, )

pub fn on_focus_changed(&mut self, id: WindowId, focused: bool)

pub fn on_redraw(&self, id: WindowId)

Trigger a repaint — sends Paint to the view thread.

pub fn on_cursor_moved( &mut self, id: WindowId, physical_x: f64, physical_y: f64, )

pub fn on_cursor_entered(&mut self, id: WindowId)

pub fn on_cursor_left(&mut self, id: WindowId)

pub fn on_mouse_input( &mut self, id: WindowId, button: MouseButton, btn_state: ButtonState, )

pub fn on_mouse_wheel(&mut self, id: WindowId, delta: WheelDelta)

pub fn on_keyboard_input( &mut self, id: WindowId, key: KeyCode, key_state: ButtonState, text: Option<String>, repeat: bool, )

pub fn on_modifiers_changed( &mut self, id: WindowId, shift: bool, ctrl: bool, alt: bool, meta: bool, )
