[Kde-accessibility] An accessible Qt? I think not.

[Leo Spalteholz]

I've run into something interesting.  Inspecting Skype (which is built
on Qt 3.2), there are no immediately obvious problems.  The menus are
perfect, and even accessible through the tree (using AccExplorer). 
Opera, on the other hand, as well as all the examples that come with
Qt4 are bad, and don't expose most functionality through MSAA.

I wonder if there were some regressions in Qt4, or if Skype did extra
work to support MSAA.
