Struct EguiWindow 

pub struct EguiWindow { /* private fields */ }

egui and the window it draws into, over whichever renderer was available. Vsync is on; every backend clears, paints and presents in Self::paint.

Implementations

impl EguiWindow

pub fn new( video: &VideoSubsystem, title: &str, size: (u32, u32), configure: impl Fn(&mut WindowBuilder), order: &[Renderer], ) -> Result<Self, String>

Try order in sequence, returning the first renderer that comes up. The error is the last attempt’s, since that is the one that decided it.

pub fn renderer(&self) -> Renderer

Which one won, for the app’s own logging and about screens.

pub fn set_rotation(&mut self, rotation: Rotation)

Present the UI at a quarter turn to the window, for a panel that is not mounted the way it is read.

egui lays out for the turned screen — a quarter turn trades the window’s width and height — and this window puts the frame back on the panel: Renderer::Gles3 and Renderer::Gl32 turn the geometry as they draw it, the SDL renderers paint offscreen and present that turned. Pointer and touch positions travel back the same way, so a tap lands where it looks. May be called at any time; nothing is rebuilt on a change of turn.

pub fn rotation(&self) -> Rotation

pub fn ctx(&self) -> &Context

pub fn window(&self) -> &Window

pub fn window_mut(&mut self) -> &mut Window

For the things SDL only does through the window itself, like Window::set_icon.

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

Feed an SDL event to egui; wgpu also resizes its surface here.

pub fn run(&mut self, run_ui: impl FnMut(&Context))

Run the UI; Self::paint puts the result on screen.

pub fn run_ui(&mut self, run_ui: impl FnMut(&mut Ui))

Like Self::run, but hands the closure egui’s root egui::Ui.

pub fn repaint_delay(&self) -> Duration

How long until egui wants another frame, from the last Self::run.

pub fn paint(&mut self, clear_color: [f32; 4])

Clear to clear_color, paint the last Self::run, present.

pub fn destroy(&mut self)

Release the renderer’s graphics resources.
