public class Gauger
extends javax.swing.JPanel
implements TickParameters, PopupManageable, StateOriginator

Gauger is a visual component that displays a value on a scale between minimum and maximum. Shape and visual layout of the component will change to best fit into the available space. Behaviour of the scale can be adjusted to fixed (lower and upper bound cannot change), constant span (scale will always span fixed ammount) or rescaling (lower and upper bound will adjust to accomodate current value). Supported scales are linear and logarithmic.

For accurate readouts, the currently set value is also displayed in custom formatted label.

Gauger is aimed to provide fastest possible response to value changes.

Constructor Detail

Gauger

public Gauger()

Creates a new gauger and sets the default parameters.

Method Detail

setScaleMode

public void setScaleMode(int mode)

Deprecated. use setValuePolicy(RangedValuePolicy)

Sets behaviour of the scale. This can take one of 3 possible modes.

• Gauger.FIXED_SCALE
• Gauger.CONSTANT_SPAN
• Gauger.STRETCH_SCALE

FIXED_SCALE will fix the limits to any value regardless of the actual value displayed by needle. If value displayed is outside limits, it will be limited to either bound.

CONSTANT_SPAN will automatically move the scale based on needle movement. If needle moves outside current limits, they will move in the same direction, but span (maximum-minimum) of the scale will remain unchanged.

STRETCH_SCALE will change only one limit at the time whenever needle moves outside current limits. Scale will not shrink back when needle is within old bounds.

Parameters:

mode - New mode to set.

setValuePolicy

public void setValuePolicy(RangedValuePolicy policy)

Sets the RangedValuePolicy.

Parameters:

policy -
