[g-a-devel]mouse events throught the at-spi registry

[David Bolter <david bolter utoronto ca>]

Bill,

Glad to see some emails from you on the list.  You must be back at work?

I am hoping you can give me some details on the mouse button events that 
are captured by the at-spi.  For starters here is my call to hook in a 
listener:
SPI_registerGlobalEventListener (mouseListener, "mouse:button");

This works fine, except in the case where a modifier key is held down. 
Is there a different way to request these events, or is this not 
available to me through the at-spi.  If not, can it be added?  (And I'll 
add thank you here for putting in the existing mouse button event stuff).

Now the background: we want the users to be able to do all the things 
current users can do with the keyboard, using the standard default key 
bindings.  One such key binding is M-Tab doing window cycling.  This is 
an interactive process whereby a user presses tab mutliple times until 
they see the window they want.  

On the gok, the user's steps are
1. simulate an alt-press (using an appropriate key on a gok keyboard).
2. simulate tab as often as needed (using the tab key on a gok keyboard).
3. simulate an alt-release

Unfortunately, if the user is driving the gok with a mouse, steps 2 and 
3 can not occur unless we can get an event for mouse presses in an "alt 
key is down context".  We do get mouse releases, but that is not good 
enough.

(BTW we are not (yet) experts on modified mouse button presses, and the 
possible interplay between the window manager etc. with respect to 
"swallowing" events.)

So... again, is it possible for us to get the mouse button press events 
in a "key modifier is down context"?

thanks as always,

David
