: I see the event.pressure (Z?) being returned by PD_Read() in
: drivers/mou_touchscreen.c,
: but it does not get used in the GdReadMouse() of engine/devmouse.c. Am I
: missing something?
No, that's correct, the Z value isn't being used by Microwindows,
but the driver can ignore Z values less than some value, if wanted.
This could affect your touch recognition...
:
: In my application I create buttons large enough to be pressed by a human
: finger, not a stylus,
: and often the key press don not get recognized. Could this be due to the
: large area that is
: being pressed? If so how could I reduce this sensitivity?
printf() the x,y values from the driver is sometimes a good way
to get an idea of what the low-level is sending Microwindows.
The problem is definitely in the kernel or Microwindows
driver, not the upper level stuff.
Reducing the sensitivity would involve changing some of the
parameters to the jitter filter, it's a bit involved, but study
that code.
