The following paragraphs describe the CLX functions used to:
A display.
A number for the acceleration ratio.
The number of pixels required for acceleration to take effect.
Changes the acceleration and/or the acceleration threshold of the pointer for the display. The :acceleration number is used as a multiplier, typically specified as a rational number of the form C/P, where C is the number of pixel positions of cursor motion displayed for P units of pointer device motion. The acceleration only occurs if the pointer moves more that :threshold pixels at once, and only applies to the motion beyond the :threshold. Either :acceleration or :threshold can be set to :default, that restores the default settings of the server.
A display.
Returns the acceleration and threshold for the display pointer.
Type number.
A display.
The type of sequence to return.
Returns or (with setf) changes the mapping of button numbers
for the display pointer. The :result-type is not used
when changing the mapping. If element i of the mapping
sequence is j, then the events from pointer button j
are reported by the server as events for button i+1. (Note
that pointer buttons are numbered beginning with one, while the
mapping sequence itself is indexed normally from zero.) If element
i of the mapping sequence is zero, then button i+1 is
disabled and can no longer generate input events. No two elements of
the mapping can have the same non-zero value.
The length of the mapping sequence indicates the actual number of buttons on the device. When changing the mapping, the new mapping must have this same length.
Type sequence or card8.
