Description

SDL 2 has quite good support for low-level functionality that is essential to games. Particularly, it supports native input APIs like XInput on Windows, for raw device events. Using SDL 2 instead of custom code and Qt for all these things (wm, video, input) should improve robustness and reduce the maintenance burden.

In practice:
  • SDL 2 should be linked to libgui and there should be a variant of GLWindow that creates an underlying SDL_Window.
  • DisplayMode should be removed and replaced with SDL video functions.
  • Qt's OpenGL API wrappers should still be usable with an SDL-created OpenGL context (after creating a QOpenGLContext representing the previously created context).

#20 Updated by skyjake over 7 years ago

When the game grabs key/mouse input, events should be received via SDL so that the appropriate low-level APIs are used.

UI event handling can still be done via Qt as currently.

I've been working on this recently, in addition to removing dependencies on Qt in the main executables. Currently debugging through a number of regressions. At least keyboard input should be much improved thanks to raw input modes.
