Create and run a simple canvas with default backend.

from rendercanvas import RenderCanvas, loop import os api_key = os.environ.get('RENDERCANVAS_API_KEY', '') # Just create a canvas with default backend canvas = RenderCanvas(title='Hello', size=(400,300)) canvas.draw(lambda: print('draw')) loop.run()

Debug

Known issues

breakingIn v2.0, the API was rewritten. Old imports like `from rendercanvas.backends import WxCanvas` no longer work. Use unified `RenderCanvas` class with backend selection via `backend` parameter.

fix

Replace with `from rendercanvas import RenderCanvas` and pass backend='wx' if needed.

affects: <2.0

breakingThe `loop.run()` call changed from `asyncio.run()` to internal event loop in v2.5. Existing asyncio code that manages its own loop may break.

fix

Use `loop.run()` provided by rendercanvas; for custom asyncio integration, see `loop.asyncio_event_loop`.

affects: >=2.5

gotchaBackend auto-detection depends on installed packages. If no backend is installed (e.g., `pip install rendercanvas` without extras), you get a RuntimeError. Always install a backend extra or check available backends.

fix

Install with e.g. `pip install rendercanvas[all]` or at least one of `[wx,qt,glfw,asyncio,jupyter]`.
