Qt itself is mostly accessible on windows. A general problem with
accessibility is that there isn't a single standard interface
(especially on non-windows), and what's been around has noticable
differences between the various screen readers. From the Qt
documentation:

| Qt supports Microsoft Active Accessibility (MSAA), Mac OS X
Accessibility, and the
| Unix/X11 AT-SPI standard. Other backends can be supported using
QAccessibilityBridge.

Problem for linux is that the AT-SPI standard isn't quite much
supported yet. I don't know about the status of screen readers on
linux, but the binaries of rbutil provided include Qt's support plugin
for accessibility. Unfortunately it's rather hard to find up-to-date
information about accessibility on linux if you're not familiar with
the topic.

On windows accessibility could be better (well, it's much better than
the situation on linux due to MSAA being more standard). We know about
an issue with tab widgets (a bug in Qt, which is fixed in Qt 4.4 --
current binaries are still built using Qt 4.3) and the item list we
use for showing the progress. I did some tests a while ago and the
results varied quite a lot depending on the screen reader.

Why don't you just try yourself if there are "major" problems
accessing rbutil using a screenreader? Unless you try you won't know
for sure, and unless we get feedback we can't improve it ...
