Patch to add bit 14 into the list of modifiers we care about (1.60 KB, patch)
2007-09-05 14:44 UTC, Willie Walker 		needs-work Details | Review

Description Willie Walker 2007-09-05 14:41:10 UTC 
When the NumLock key is locked, Orca doesn't receive any keyboard events.  This affects Orca's ability to interrupt speech and handle any other Orca keystrokes.

From private e-mail with Li Yuan:

"Just looked at the code. You can refer to
http://svn.gnome.org/viewcvs/at-spi/trunk/registryd/deviceeventcontroller.c?view=diff&r1=417&r2=418
and http://bugzilla.gnome.org/show_bug.cgi?id=107261 .
SPI_KEYMASK_NUMLOCK is defined as (1<<14).

Bill added this because the NumLock mask can be different on different
keyboards."

While it is exposed to assistive technologies by being set in modifier masks, I don't see SPI_KEYMASK_NUMLOCK exposed to us as a value we can use.  So, we might need to hack and force registration for events containing a set bit 14.

Patch to add bit 14 into the list of modifiers we care about

This patch adds knowledge of bit 14 into the registration of key events, but it doesn't seem to work.  I suspect there might be bugs lurking in AT-SPI.

BTW, see also http://mail.gnome.org/archives/orca-list/2007-August/msg00290.html for more information on this bug.
