Struct egui::PaintCallback

pub struct PaintCallback {
    pub rect: Rect,
    pub callback: Arc<dyn Fn(&PaintCallbackInfo, &(dyn Any + 'static)) + Sync + Send + 'static>,
}

If you want to paint some 3D shapes inside an egui region, you can use this.

This is advanced usage, and is backend specific.

Fields

rect: Rect

Where to paint.

callback: Arc<dyn Fn(&PaintCallbackInfo, &(dyn Any + 'static)) + Sync + Send + 'static>

Paint something custom (e.g. 3D stuff).

The argument is the render context, and what it contains depends on the backend. In eframe it will be egui_glow::Painter.

The rendering backend is responsible for first setting the active viewport to Self::rect.

The rendering backend is also responsible for restoring any state, such as the bound shader program and vertex array.

Implementations

impl PaintCallback

pub fn call(&self, info: &PaintCallbackInfo, render_ctx: &(dyn Any + 'static))
