Function Documentation

pub fn convert_sdl_event(
	ev: &Event,
	pixel_scale_x: f32,
	pixel_scale_y: f32
) -> Option<UiEvent>

Convert one SDL3 event into a UiEvent. pixel_scale_x / pixel_scale_y convert logical SDL coordinates to physical pixels. Obtain them with window_pixel_scale before calling this. Returns None for SDL events that have no UI representation (timers, audio device changes, etc.).

pub fn window_pixel_scale(window: &Window) -> (
	f32,
	f32
)

Compute logical→physical pixel scale for one window. Returns (scale_x, scale_y). Both default to 1.0 when the window is zero-size or the query fails.
