The accept attribute of the <input /> tag does not work

[whatever_name]

Setting <input type="file" id="filepicker" accept=".cpp, .html, .h, .png, .qdoc, .qml" />, then click the input button, the file dialog pops up, but the file type filter does not work.

Qt widgets or QML?

Anyway the docs say:

acceptedMimeTypes is ignored by the default implementation, but might be used by overrides.

For QML follow the same principle.

Thanks @raven-worx
Overrides the chooseFiles() is a good solution for me.
