[g-a-devel] intercepting keys

[Mike Gorse <mgorse mgorse dhs org>]

Hi all,

Can someone explain how the registry daemon is supposed to listen for 
keyboard events?  There is a function in deviceeventcontroller.c called 
spi_controller_register_global_keygrabs which looks like it's supposed to 
cause the daemon to grab keys, but it seems to do nothing on my system. 
Instead, it looks like it is each application's responsibility to pass 
keys along so that, say, Orca will see them (this is done by gail for gtk 
applications); otherwise Orca won't know if a user presses one of its hot 
keys.  We don't currently have code in the UIA-to-ATK bridge to handle 
this, so I'm trying to figure out if we need code to intercept keys and 
pass them on to the registry.

Thanks,
