Hi,
I'm trying to resolve a problem in Wine when using a non-us keyboard. Maybe
some keyboard specialist could help me. Here's the problem:
Most of the non-us keyboard are configured to display different characters
if the right Alt key(AltGr) is pressed.
Ex: With the French keyboard:
Key pressed Result
3 --> '"'
Shift+3 --> '3'
AltGr+3 --> '#'
With Wine AltGr+3 will return the same value as if you haven't pressed
AltGr. I've looked at the code and everything seems to be there to handle
this case. So I've digged down a little more and I found:
1. At initialization time in X11DRV_KEYBOARD_Init(), Wine is trying to find
what is the modifier index for AltGr by calling XGetKeyboardMapping(). X
doesn't return AltGr as a modifier key. Why AltGr is not a modifier?
2. When handling XKeyEvent in function X11DRV_KEYBOARD_HandleEvent(), Wine
use function XLookupString() to find the string associated to the XKeyEvent.
So with the French keyboard I'm seeing:
When I'm pressing 3 --> XKeyEvent.state=0 XKeyEvent.keycode=0x0c -->
XlookupString return '"'
When I'm pressing AltGr+3 --> XKeyEvent.state=0 XKeyEvent.keycode=0x0c -->
XlookupString return '"'
When receiving the key event how can I differentiate between those two
events? Other Linux programs are dealing correctly with this situation, what
do you think they are doing differently?
Any help will be appreciated.
