: I'm a little lost with the X11 driver. I need to know when a key is
: released and watch for KEY_UP events. Basically it works fine but the
: problem is the auto repeat function. For every auto repeat cycle I get
: KEY_DOWN * AND KEY_UP * event (DOWN UP DOWN UP DOWN UP ... DOWN UP; I
: was expecting a sequence of DOWN DOWN DOWN ... DOWN UP). These extra
: KEY_UP events makes it impossible to distinguish between multiple key
: presses and one long press.
:
: Is this a property of X11 and is there any way to modify it's behaviour?
Timo,
Yes, this is an X11 issue. You might want to look at how the Linux
console scancode driver solves this problem (src/drivers/kbd_ttyscan.c)
There's an #if 0 on line 345 that basically drops events that don't change
state. This code needs to be basically inserted into the kbd_x11.c
x11 kbd driver in the X11_Read function, in near the same area.
Regards,
Greg
