Re: [orca-list] orca and QT

[Michael Whapples <mwhapples aim com>]

So the claim in the other improvements list for what's new in QT4.3:
      * "Expanded accessibility support; now approaching 100% widget
        coverage on all platforms"
      * And the statement from the QT 4.3 documentation in the
        accessibility section:
      * "Qt currently supports three technologies: Microsoft Active
        Accessibility (MSAA), Mac OS X Accessibility, and Unix/X11
        AT-SPI."
      * are misleading at best.
      * 
      * From what I could find online you seem to be correct with what
        you said, but I thought I would ask as those quotes I have given
        indicate strongly otherwise.
      * 
      * From
      * Michael Whapples
