Re: [orca-list] nvda under the Wine

[Petr Bláha <hammet pb seznam cz>]

Hi, this explanation seems to be quite clear and it makes sense for me.
I use linux as a secondary OS, i am mostly windows user.
And to be honest, i have to say that few months ago, i started to use 
linux more and more. I like it's filosofy as well as all the other 
things that makes it so attractive for many blind, and not only blind users.
But on the other hand there are some problems which force me not to 
leave windows and use only Linux.
The biggest one is absolutely no accessibility of QT applications by orca.
And my experience is so that the best applications in linux are QT based.
For example kaffeine for TV carts, skype for communication, and many 
others, which we can't use at all.
I also didn't find any good quality application for book scanning, which 
is quite important for me as a blind user and book fann.
In windows i use Abbyy Finereader, which is for sale, but you pay for 
software which allows you to scann at great quality and in many languages.
I didn't find such an alternative in linux which can be compared with 
Finereader.
The thirt reason for me is Audio games for the blind.
I use computer mostly for serious work, but sometimes, i would like to 
use it for entertainment as well and i am absolutely not able to play 
audio games in it.
I mean these like Gma tank commander, shades of doom three d velocity, 
and many others.

So these reasons are as important for me, so i still have windows 
installed in my PC and i won't uninstall it.
