public class TraceRecorder

extends BaseGauge

implements Serializable

TraceRecorder()

Construct a TraceRecorder with an initial value of 0 and a range from 0 to 100.

TraceRecorder(int, int, int)

Minimal constructor which accepts only the initial value, the minimum value and the maximum value.

TraceRecorder(int, int, int, int, long, int, Color, Color)

Create a new TraceRecorder specifying the number of pixels the trace scrolls on each update, the maximum interval in milliseconds between updates, the number of horizontal scale lines required, the color of the lines, and the color used to fill the area under the trace line.

copyright()

gaugeModelChanged(GaugeModelChangeEvent)

This method can be overriden by extending classes which need to react to a change to one or more of the models settings.

getAdvance()

Return the number of pixels that the trace will advance by.

getFillColor()

Return the color used to fill the area under the trace.

getInterval()

Return the millisecond interval between advances.

getMinimumSize()

getNumberOfLines()

Return the number of scale lines on the TraceRecorder.

getScaleColor()

Return the color of the scale.

getTraceColor()

'get' accessor method for traceColor.

paintComponent(Graphics, Dimension, int, int, int)

Paint the gauge.

processComponentEvent(ComponentEvent)

setAdvance(int)

Set the number of pixels that the trace advances by in each step.

setBackground(Color)

setFillColor(Color)

Specify the color used to fill the area under the trace.

setInterval(long)

Specify the millisecond interval b etween advances.

setNumberOfLines(int)

Set the number of scale lines on the TraceRecorder.

setScaleColor(Color)

Set the scale color.

setTraceColor(Color)

'set' accessor method for traceColor.

 public TraceRecorder(int initialValue,
                      int minimum,
                      int maximum,
                      int advance,
                      long interval,
                      int numberOfLines,
                      Color scaleColor,
                      Color fillColor)

Create a new TraceRecorder specifying the number of pixels the trace scrolls on each update, the maximum interval in milliseconds between updates, the number of horizontal scale lines required, the color of the lines, and the color used to fill the area under the trace line. The interval can be specified as INDEFINITE_WAIT, in which case the gauge updates only when the value changes.

 public TraceRecorder(int initialValue,
                      int minimum,
                      int maximum)

Minimal constructor which accepts only the initial value, the minimum value and the maximum value. The remaining properties default to a 2 pixel advance, a 10 millisecond interval, 7 black scale lines and a blue fill.

 public TraceRecorder()

Construct a TraceRecorder with an initial value of 0 and a range from 0 to 100. The remaining properties default to a 2 pixel advance, a 200 millisecond interval, 7 black scale lines and a blue fill.

 public static String copyright()

 public long getInterval()

Return the millisecond interval between advances.

 public void setInterval(long interval)

Specify the millisecond interval b etween advances.

 public int getAdvance()

Return the number of pixels that the trace will advance by.

 public void setAdvance(int advance)

Set the number of pixels that the trace advances by in each step.

 public int getNumberOfLines()

Return the number of scale lines on the TraceRecorder.

 public void setNumberOfLines(int numberOfLines)

Set the number of scale lines on the TraceRecorder.

 public Color getScaleColor()

Return the color of the scale.

 public void setScaleColor(Color color)

Set the scale color. Null will be ignored.

 public Color getFillColor()

Return the color used to fill the area under the trace.

 public void setFillColor(Color color)

Specify the color used to fill the area under the trace. Null is ignored.

 public void setTraceColor(Color color)

'set' accessor method for traceColor.

 public Color getTraceColor()

'get' accessor method for traceColor.
