public class Slider extends Control
The three fundamental variables of the slider are min
,
max
, and value
. The value
should always
be a number within the range defined by min
and
max
. min
should always be less than or equal to
max
(although a slider whose min
and
max
are equal is a degenerate case that makes no sense).
min
defaults to 0, whereas max
defaults to 100.
This first example creates a slider whose range, or span, goes from 0 to 1, and whose value defaults to .5:
Slider slider = new Slider(0, 1, 0.5);
This next example shows a slider with customized tick marks and tick mark labels, which also spans from 0 to 1:
Slider slider = new Slider(0, 1, 0.5); slider.setShowTickMarks(true); slider.setShowTickLabels(true); slider.setMajorTickUnit(0.25f); slider.setBlockIncrement(0.1f);

ormax
changing or due to itself being changed, then it will be clamped to always remain valid.- See Also:
