QT is a different GUI toolkit; it uses its own widgets, not native
Windows widgets. Under Windows, it implements its own MSAA support to
provide accessibility for these widgets. If I recall correctly, the
window class of QT widgets is usually not useful at all; I think it is
always "QWidget", which obviously isn't unique to the type of the
control. Thus, reclassing won't help. Even if the class *was* different,
it probably wouldn't help. Reclassing mostly depends on the control
reacting to specific Windows API calls and messages, which QT widgets
will not do.

It should be a static text control or a label. Unfortunately, QT is a
bit broken in terms of the way it renders messages like this to
accessibility APIs. Actually, QT's accessibility support is broken in
several rather frustrating ways. :)
