Struct Renderer 

pub struct Renderer<'a> { /* private fields */ }

Represents the context for the renderer

Implementations

impl<'a> Renderer<'a>

pub fn new( texture_creator: &'a TextureCreator<impl Any>, imgui_context: &mut Context, ) -> Result<Self, RenderError>

Constructs a new Renderer

Examples

Make sure to call after setting the imgui font.

let sdl_context = sdl3::init().unwrap();
let video_subsystem = sdl_context.video().unwrap();

let window = video_subsystem
    .window("rust-sdl3 example", 800, 600)
    .position_centered()
    .resizable()
    .high_pixel_density()
    .build()
    .unwrap();
let mut canvas = window.into_canvas();
let texture_creator = canvas.texture_creator();

let mut imgui_context = imgui::Context::create();
imgui_context.set_ini_filename(None);

imgui_context.fonts().add_font(&[imgui::FontSource::DefaultFontData { config: None, }]);

let mut renderer = imgui_sdl3_renderer::Renderer::new(&texture_creator, &mut imgui_context).unwrap();

pub fn render( &mut self, draw_data: &DrawData, canvas: &mut Canvas<impl RenderTarget>, ) -> Result<(), RenderError>

Renders the draw_data to the canvas

The canvas must be the canvas that owns the [TextureCreator] that was passed to Self::new and must be the same canvas on each call

Examples

/* ... */
let mut canvas = window.into_canvas();
let texture_creator = canvas.texture_creator();

/* ... */
let mut renderer = imgui_sdl3_renderer::Renderer::new(&texture_creator, &mut imgui_context).unwrap();

'main loop {
canvas.clear();
/* ... */
let ui = imgui_context.new_frame();
ui.show_demo_window(&mut true);
renderer.render(imgui_context.render(), &mut canvas).unwrap();
/* ... */
canvas.present();
}
