Re: [orca-list] Possible toggling six dots and eight dots braille output?

[Hammer Attila <hammera pickup hu>]

Hy,

Joanie, before I doing any bugreport or enhancement requests this 
problem related, I write my summary experiences to clear I detected 
right what the problem now for dot mode switch function for Orca related:
Temporary I disabled following braille binding keystrokes my local Orca 
3.1.2Pre version source code in src/orca/scripts/default.py file to look 
Orca pass Brltty the textstyle switch command eight dots or six dots 
mode command or not if Contraction tables related keystroke is not present:
            brailleBindings[braille.brlapi.KEY_CMD_SIXDOTS]   = \
                self.inputEventHandlers["contractedBrailleHandler"]

After I recompile and restart Orca, I try press together help and info 
buttons my Alva Satelite 570Pro braille display, this keystroke switch 
text console the text style with eight dots and six dots text mode.
Results:
When I press this two keystrokes together, nothing happening. The text 
style doesn't change from eight dots to six dots mode in graphical session.
Happening this because Orca doesn't pass this command with Brltty? 
Contracted braille is not enabled of course when I doed this test.

Little quote with Brltty reference manual:
"SIXDOTS

    Show characters using 6-dot, rather than 8-dot, braille. Dots 7 and 
8 are still used by other features like cursor representation and 
highlighted character underlining. If a contraction table has been 
selected (see the -c command line option and the contraction-table 
configuration file directive), then it is used. This setting can also be 
changed with the Text Style preference.

Text Style

    When displaying screen content (see the DISPMD command), show 
characters:

    8-dot

        With all eight dots.
    6-dot

        With only dots 1 through 6. If a contraction table has been 
selected (see the -c command line option and the contraction-table 
configuration file directive), then it is used.

    This setting can also be changed with the SIXDOTS command."
I don't understand a think:
I setted text style preference with six dots mode with Brltty 
preferences (press my braille display the preferences button before I 
doing this), and of course saved the changed preferences.
In text console, this is working default fine. Why owerwrite Orca this 
setting and restore the eight dots text style mode by default if 
contracted braille is not enabled?
I no, Orca contracted braille function is a different function, because 
using Liblouis tables if contracted braille enabled, not Brltty tables.

So, my questions before I doing proper bugreports with proper components 
for Orca related:
1. Have a chance to possible future choose anyway the text style mode 
with Orca braille mode between six dots and eight dots mode without need 
creating two different braille table if Brltty the used braille output 
driver? Or, both two function possible choosing this mode?
2. If not, because technical not possible implementing this feature, and 
need creating two style tables for Brltty, have a chance to possible 
choose what table are want use the user, similar with Liblouis 
contraction tables?
3. How can possible working text style switch mode between eight dots 
and six dots modes if in Orca enabled the contracted braille feature, 
and Liblouis tables are used if possible implementing this function?
