Constructor Detail

JMeter

public JMeter()
Default constructor (parameter-less).

JMeter

public JMeter(java.awt.Color bg,
              java.awt.Color fg)
Constructor with user-defined background and foreground.
Parameters:
bg - initial background color
fg - initial foreground color, color of text

JMeter

public JMeter(int leftAccuracy,
              int rightAccuracy)
Constructor with user-defined left and right of decimal accuracy.
Parameters:
leftAccuracy - accuracy of digits to the left of decimal
rightAccuracy - accuracy of digits to the right of decimal

JMeter

public JMeter(int leftAccuracy,
              int rightAccuracy,
              java.awt.Color bg,
              java.awt.Color fg)
Constructor with user-defined accuracy and colors.
Parameters:
leftAccuracy - accuracy of digits to the left of decimal
rightAccuracy - accuracy of digits to the right of decimal
bg - initial background color
fg - initial foreground color, color of text
Method Detail

Init

protected void Init()
Initializations common to all constructors.

getLeftAccuracy

public int getLeftAccuracy()
Accessor for number left accuracy.
Returns:
the maximum number of digits to left of decimal

getRightAccuracy

public int getRightAccuracy()
Accessor for right accuracy.
Returns:
the maximum number of digits to right of decimal

setLeftAccuracy

public void setLeftAccuracy(int n)
Mutator for left accuracy.

setRightAccuracy

public void setRightAccuracy(int n)
Mutator for left accuracy.

setText

public void setText(java.lang.String s)
Disabled for safety purposes.
Overrides:
setText in class javax.swing.text.JTextComponent

setValue

public void setValue(short num)
Set the value of the meter using data of type short.

setValue

public void setValue(int num)
Set the value of the meter using data of type int.

setValue

public void setValue(long num)
Set the value of the meter using data of type long.

setValue

public void setValue(double num)
Set the value of the meter using data of type double.

resetMeter

public void resetMeter()
Meter is zero'ed.

redrawMeter

public void redrawMeter()
Redraws the meter. When the user changes the accuracy of the number being displayed, the TextField (view) as well as the text inside must be re-calculated. This is basically the same code as the setValue() method, except due to changes in the left and/or right accuracy, the textfield needs to be resized.

processComponentKeyEvent

protected void processComponentKeyEvent(java.awt.event.KeyEvent event)
Disallows special key input.
Overrides:
processComponentKeyEvent in class javax.swing.text.JTextComponent

processInputMethodEvent

protected void processInputMethodEvent(java.awt.event.InputMethodEvent event)
Disallows normal user input.
Overrides:
processInputMethodEvent in class javax.swing.text.JTextComponent
