Seems to confirm it, but doesn't. What that means is Qt uses the native style APIs to get the system styles (e.g., theme color, highlight colors, default fonts/sizes, etc.), so it can draw controls that look like native controls. But it's drawing widgets, not using native widgets. In many/most cases, users will never know the difference, but it is different.

Blind users definitley notice the difference, because Qt apparently doesn't implement the platform accessibility APIs quite right, particularly on WIndows.

Two anecdotes:

1. The TeamTalk (http://bearware.dk/) voice chat system is popular among blind people. Originally when it was Windows only, it was an MFC application. Then when it went cross-platform, the developer used Qt. But the Qt version was inferior for blind users, so the developer still maintains the MFC version just for them.

2. Rant from a blind programmer trying to develop an accessible cross-platform application with Qt: https://blind.guru/qta11y.html

On every major platform, it's possible for non-native widgets to be accessible by implementing the platforms' accessibility APIs. But Qt doesn't do this very well.
