XChangePointerControl(3X) — X Version 11

NAME

XChangePointerControl, XGetPointerControl − control pointer

SYNTAX

XChangePointerControl(display, do_accel, do_threshold, accel_numerator,
                        accel_denominator, threshold)
      Display ∗display;
      Bool do_accel, do_threshold;
      int accel_numerator, accel_denominator;
      int threshold;

XGetPointerControl(display, accel_numerator_return, accel_denominator_return,
                       threshold_return)
      Display ∗display;
      int ∗accel_numerator_return, ∗accel_denominator_return;
      int ∗threshold_return;

ARGUMENTS

accel_denominator
Specifies the denominator for the acceleration multiplier.

accel_denominator_return
Returns the denominator for the acceleration multiplier.

accel_numerator
Specifies the numerator for the acceleration multiplier.

accel_numerator_return
Returns the numerator for the acceleration multiplier.

displaySpecifies the connection to the X server.

do_accelSpecifies a boolean value that controls whether the values for the accel_numerator or accel_denominator are set. You can pass one of these constants: True or False.

do_thresholdSpecifies a boolean value that controls whether the value for the accel_numerator or accel_denominator are set. You can pass one of these constants: True or False.

thresholdSpecifies the acceleration threshold.

threshold_return
Returns the acceleration threshold.

DESCRIPTION

The XChangePointerControl function defines how the pointing device moves. .PN XChangePointerControl can generate a BadValue error.

The XGetPointerControl function returns the pointer’s current acceleration multiplier and acceleration threshold.

DIAGNOSTICS

BadValue Some numeric value falls outside the range of values accepted by the request. Unless a specific range is specified for an argument, the full range defined by the argument’s type is accepted. Any argument defined as a set of alternatives can generate this error.
