.. currentmodule:: sdl2.ext
Initialization routines
=======================
:func:`init()` simply calls :func:`SDL_Init()` to initialize only the video
subsystem. If the call fails, :exc:`SDLError` is raised. See
:ref:`pygamers_pygame` for a comparison between this function and
:func:`pygame.init()`.
API
---
.. exception:: SDLError(msg=None)
An SDL2 specific :class:`Exception` class. if no *msg* is provided,
the message will be set to the value of :func:`sdl2.error.SDL_GetError()`
.. function:: init() -> None
Initialises the underlying SDL2 video subsystem. Raises a
:exc:`SDLError`, if the SDL2 video subsystem could not be
initialised.
.. function:: quit() -> None
Quits the underlying SDL2 video subysystem. If no other SDL2
subsystems are active, this will also call :func:`quit()`,
:func:`sdl2.sdlttf.TTF_Quit()` and :func:`sdl2.sdlimage.IMG_Quit()`.
.. function:: get_events() -> [SDL_Event, SDL_Event, ...]
Gets all SDL events that are currently on the event queue.
.. class:: TestEventProcessor()
A simple event processor for testing purposes.
.. method:: run(window : Window) -> None
Starts an event loop without actually processing any event. The method
will run endlessly until a ``SDL_QUIT`` event occurs.
