Struct egui_winit::State

pub struct State { /* private fields */ }

Handles the integration between egui and winit.

Implementations

impl State

pub fn new<T>(event_loop: &EventLoopWindowTarget<T>) -> Self

pub fn new_with_wayland_display(wayland_display: Option<*mut c_void>) -> Self

pub fn set_max_texture_side(&mut self, max_texture_side: usize)

Call this once a graphics context has been created to update the maximum texture dimensions that egui will use.

pub fn set_pixels_per_point(&mut self, pixels_per_point: f32)

Call this when a new native Window is created for rendering to initialize the pixels_per_point for that window.

In particular, on Android it is necessary to call this after each Resumed lifecycle event, each time a new native window is created.

Once this has been initialized for a new window then this state will be maintained by handling winit::event::WindowEvent::ScaleFactorChanged events.

pub fn pixels_per_point(&self) -> f32

The number of physical pixels per logical point, as configured on the current egui context (see egui::Context::pixels_per_point).

pub fn egui_input(&self) -> &RawInput

The current input state. This is changed by Self::on_event and cleared by Self::take_egui_input.

pub fn take_egui_input(&mut self, window: &Window) -> RawInput

Prepare for a new frame by extracting the accumulated input, as well as setting the time and screen rectangle.

pub fn on_event(
    &mut self,
    egui_ctx: &Context,
    event: &WindowEvent<'_>
) -> EventResponse

Call this when there is a new event.

The result can be found in Self::egui_input and be extracted with Self::take_egui_input.

pub fn handle_platform_output(
    &mut self,
    window: &Window,
    egui_ctx: &Context,
    platform_output: PlatformOutput
)

Call with the output given by egui.
