Move the slider this much per click.
This attribute specifies how much a slider increments when the user clicks the central portion of the slider. The default amount is 1/10 of the total range between the minimum value (specified by the min_value attribute) and the maximum value, specified by the max_value attribute.
For int, specify an integer in the range between min_value and max_value.
Example
min_value = -16;
max_value = 16;
small_increment = 1;
big_increment = 10;
