public class MovingSlider

extends javax.swing.JSlider

Slider that moves the labels and slider position as the user moves the slider to the right or to the left, to allow for a greater range of values than that of a regular slider. For example, if the user moves the slider from 20 to 40, when there is an actual maximum of 100, and a displayed maximum of 50, the slider labels might move to the right so 70 would be visible.

The displayed minimum will always be a multiple of the major tick spacing. The display range must be at least equal to the difference between the real maximum and the real minimum.

Sets the minimum number of values to the left of the slider position that should be displayed. This value will be used, unless the slider is less than leftMargin away from the actual minimum, or if a displayed minimum must be chosen so as to be a multiple of majorTickSpacing.

Parameters:

newLeftMargin - new value for left margin
