- This driver lets use a Graphical User Interface as BrlTTY device:
- it behaves just like a real braille device, its cost excepted :)
-
- It is mostly intended for sighted developers who don't have access to a real
- device, but still want to have an idea of the accessiblity of their application.
-
- Assuming you're under X, first launch brltty:
- $ brltty -b xw -x as
-
- Then you can launch a BrlAPI application:
- $ ~/brltty/Programs/apitest
- or you can launch text applications in AT-SPI terminals like gnome-terminal.
-
- You may give several parameters to the driver:
- $ brltty -b xw -t identity -B tkparms="-geometry -0+0 -display :1",lines=2,cols=20,model=bare
- will set a 20x2 braille display appear in the upper right corner of the
- :1 display, without any navigation key. There is also the vs model which
- will show up most of VisioBraille device's keys.
-
- You should configure your window manager not to let the BRLTTY window get
- keyboard focus, so as to be able to simulate keypresses by pressing buttons.
- Or you may use the -display tkparameter option to display the emulated device
- on another X server and add the input=on option so that keypresses in the
- device window will get simulated in the original display.
-
- *** Don't set input=on without using -display too on a different display,
- because else emulated keypresses will just loop ! ***
-
- If you want braille display as well, you'll need the ClearlyU font
- (included in recent xfonts-base packages) and a UTF-8 locale for
- characters: if your usual locale is en_US, launch brltty with a
- prepended LC_CTYPE:
-
- LC_CTYPE=en_US.UTF-8 brltty ...
