Issue №2316 opened by illume at 2020-11-11 07:58:21

WIP: this issue is a work in progress.

The display.set_mode function is too complex. See Complexity of C code issue on how to measure complexity.

There's quite a few issues with pygame.display.set_mode, including: # 212, # 993, # 2100, # 2186 and # 2132 A bunch of the features are not tested or documented. There's perhaps new functionality wanted including for setting window size. Additionally it is not well encapsulated.

What's needed is a slow process of refactoring to reduce complexity. Smaller functions, documentation and testing.

1. Some of the linked issues are problems in SDL2 itself
2. Some of the complexity in set_mode and toggle_fullscreen is due to bugs in older versions of SDL2
3. Many currently open feature requests are likely to require adding more complexity to set_mode (like fast size changing)

I suspect just breaking it down into a bunch of sub-functions would help a lot.

I'm going to clear up a little bit. (Adding comments and so forth)

Well, I looked at it and it doesn't make any sense. I can add comments after somebody splits it up, though. Sorry!
