AnalogMeter

public AnalogMeter(int width,
                   int height,
                   int meterMode,
                   java.lang.String fontName,
                   int fontStyle,
                   int fontSize,

                   java.awt.Color panelColor,
                   java.awt.Color needleColor,
                   java.awt.Color textColor)

Analog Meter Class Constructor with all agruments

Parameters:

width - is the width in pixels of the meter

height - is the height in pixels of the meter

meterMode - is not currently used

fontName - is the name of the font for labelling

fontStyle - is the name of the font style for labelling

fontSize - is the size of the font for labelling

caption - is the caption to label the meter with

hasLabels - is true if the meter has labels and it is desired they are displayed.

labelsString - is the string of comma separated label strings used to label the meter. There can be any number specified and the analog meter will spread them evenly across the scale.

labelPercent - is the percentage relative to the meter's height where the labels will be drawn. Labels are drawn radially.

value - is the value the meter should initially display

hasHighlight - is true if highlighting should be used for the meter's display. Currently unused here.

panelColor - is the color of the panel surrounding the meter.

needleColor - is the color of the meter's needle

textColor - is the color used for the labelling text

AnalogMeter

public AnalogMeter(int width,
                   int height,
                   java.lang.String caption,
                   int value)

Analog Meter Class Constructor with reasonable defaults

AnalogMeter

public AnalogMeter()

Analog Meter Class Constructor with zero arguments. Needed for use as a bean.

Method Detail

stateChanged

public void stateChanged(javax.swing.event.ChangeEvent e)

Specified by:

stateChanged in interface javax.swing.event.ChangeListener

paint

public void paint(java.awt.Graphics g)

Paint the Analog Meter onto the graphics context. Double buffering is used to reduce flicker.

Overrides:

paint in class java.awt.Container

Parameters:

g - is the graphics context on which to draw

getPreferredSize

public java.awt.Dimension getPreferredSize()

Return the preferred size of this analog meter

Overrides:

getPreferredSize in class java.awt.Container

Returns:

Dimension object containing the preferred size of the meter

resetMeterColorZones

public void resetMeterColorZones()

Reset all of the color zones used for the meter. This allows the zones to be changed at runtime if needed.

setColorRange

public void setColorRange(java.awt.Color color,
                          double minPercentValue,
                          double maxPercentValue)

Set a color for a range of values on the meter's scale. Creates a new MeterColorZone object to describe the range. NOTE: this isn't any overlap checking done here so the most recent range set sticks.

Parameters:

color - is the color for the specified range of values

minPercentValue - is the percentage of full scale value where this color should begin

maxPercentValue - is the percentage of full scale value where this color should end

setLabelPercent

public void setLabelPercent(int percent)

Sets the distance as a percent of meter height where the meter labels should be placed.

Overrides:

setLabelPercent in class Meter

Parameters:

percent - is the percent value

main

public static void main(java.lang.String[] args)
