Web Assembly: QtQuick or QtWidget?

[Dave von Orlando]

Hi, I'm approaching to Qt6 to create wasm application.
But, for example, QMessageBox does not work on them. I have Qt6.8 and Emscripten ver. 1.3.56.
QtQuick use Dialog, but QtWidget?

@Dave-von-Orlando
Never used WASM, but e.g. https://bugreports.qt.io/browse/QTBUG-116608 (the bug is not important, and was fixed anyway) shows a user using QMessageBox in WASM? It says "Tested on 6.5.2 (single threaded, no async)", I don't know if that affects you.

@JonB Yup that is me. It works just fine. He probably just used .exec() which will cause the application to crash without asyncify. You should use .show() instead.
