PySDL2: Creating a borderless window

I've been trying to find how I might create a borderless window (One not created using the typical windows border) in PySDL2.

I've looked at what resources I could find online, but haven't been able to pinpoint anything that would tell me how to accomplish this, despite it being apparently possible.

Research:

1. This link states that in most cases you have a border and title bar around your window, but never went into any more detail as to how to manipulate it.

2. I looked at some API references for SDL's Window, and did not see that borders could be manipulated at all. (Not stated that they couldn't be, just no mention)

---

Despite not finding anything PySDL2 related, I did find at this link that:

sdl.setWindowBordered(window, bordered)
Sets the border state of a window.

Unfortunately, I'm unable to get this to work within my simple example script.

Thanks for looking!

You need to make sure you have the flag: SDL_WINDOW_BORDERLESS.

Full example:

import sys
import sdl2.ext

sdl2.ext.init()

window = sdl2.ext.Window("Hello World!", size=(640, 480), flags=sdl2.SDL_WINDOW_BORDERLESS)
window.show()

processor = sdl2.ext.TestEventProcessor()
processor.run(window)

Modifying your script slightly we get:

import sys
import sdl2.ext

def run():
    sdl2.ext.init()
    W = sdl2.ext.Window("Default",size=(400,300), flags=sdl2.SDL_WINDOW_BORDERLESS)
    W.show()
    running = True
    while running:
        events = sdl2.ext.get_events()
        for event in events:
            if event.type == sdl2.SDL_QUIT:
                running = False
                break
        W.refresh()
    return 0

if __name__ == "__main__":
    sys.exit(run())
