Struct State 

pub struct State { /* private fields */ }

Handles the integration between egui and a sdl3 Window.

Instantiate one of these per viewport/window.

Implementations

impl State

pub fn new(window: &Window, egui_ctx: Context, viewport_id: ViewportId) -> Self

pub fn get_window_size(&self) -> (u32, u32)

pub fn get_drawable_size(&self) -> (u32, u32)

Drawable (physical pixel) size, cached and refreshed on resize.

This is the size a GPU backend should use for its viewport/framebuffer: on HiDPI it differs from Self::get_window_size (logical points).

pub fn get_pointer_pos_in_points(&self) -> Option<Pos2>

pub fn set_theme(&mut self, theme: Theme)

pub fn handle_platform_output(&mut self, platform_output: PlatformOutput)

Call with the output given by egui.

This will, if needed:

• update the cursor
• copy text to the clipboard
• open any clicked urls

pub fn take_egui_input(&mut self) -> RawInput

Prepare for a new frame by extracting the accumulated input,

as well as setting the time

You need to set egui::RawInput::viewports yourself though.

pub fn on_event(&mut self, window: &Window, event: &Event) -> EventResponse

Call this when there is a new event.

The result can be extracted with Self::take_egui_input.

pub fn sync_window_size(&mut self, window: &Window)

Refresh the cached window/drawable size and native pixels-per-point from the live window. Call once per frame so an orientation change is reflected even when the platform doesn’t deliver a size-changed event (Android is unreliable here — the surface can resize on rotation without an event).
