VIDEORESIZE events

[TomFryers]

Pygame supports creating resizable windows. However, I don't think these are getting passed through from the browser.

Here's an example that works on my desktop, but not through pygbag.

import asyncio

import pygame


def sane_font(width, height):
    return pygame.font.Font(None, round(min(height, width) * 0.2))


async def main():
    pygame.init()

    width = 1280
    height = 720
    S = pygame.display.set_mode((width, height), pygame.RESIZABLE)

    font = sane_font(width, height)
    while True:
        for event in pygame.event.get():
            if event.type == pygame.VIDEORESIZE:
                width, height = S.get_size()
                font = sane_font(width, height)
        S.fill((255, 255, 255))
        S.blit(font.render(f"{width} × {height}", True, (0, 0, 0)), (5, 5))
        pygame.display.update()
        await asyncio.sleep(0)


asyncio.run(main())

Pygbag does well at scaling up non-resizable windows, but where the author's gone to the trouble of handling resizes, crisp graphics would be really nice to have.

Resizable windows will not be supported by pygbag, soft rendering makes it too heavy on mobile/hdpi cpu. Use 1024x600 or 1280x720 and let the hardware scaler handle your window, you can get pixelated effects back with

import sys, platform
if sys.platform == "emscripten":
    platform.window.canvas.style.imageRendering = "pixelated"

[TomFryers]

Could the window be resizeable, maintaining the correct aspect ratio, but with with a cap on total area? That way, moderate resolutions look crisp and grey-bar-less, but slower devices can still cope.

Maybe but i won't try to do it, as it does not fit general usage. Also complexity required to make that work is maybe more than i can evaluate right now.

if you want to try handle canvas (framebuffer) resizing yourself you can call platform.window.vm.config.user_canvas_managed = 0 python side or overload window.window_resize_2d js side
