Class IndexedPairVariableValue

java.lang.Object
  jmri.jmrit.symbolicprog.AbstractValue
      jmri.jmrit.symbolicprog.VariableValue
          jmri.jmrit.symbolicprog.IndexedPairVariableValue

All Implemented Interfaces:

ActionListener, FocusListener, PropertyChangeListener, EventListener

public class IndexedPairVariableValue
extends VariableValue
implements ActionListener, PropertyChangeListener, FocusListener

Extends VariableValue to represent a indexed variable split across two indexed CVs. Factor is the multiplier of the value in the high order CV Value to put in High CV = (value in text field)/Factor Value to put in Low CV = (value in text field) - High CV value Value to put in text field = ((value in High CV) * Factor) + Low CV

Method Detail

usesCVs

public CvValue[] usesCVs()

Description copied from class: VariableValue

Provide access to CVs referenced by this operation

Specified by:

usesCVs in class VariableValue

setToolTipText

public void setToolTipText(String t)

Description copied from class: VariableValue

Set tooltip text to be used by both the "value" and representations of this Variable.

This is expected to be overridden in subclasses to change their internal info.

Overrides:

setToolTipText in class VariableValue

See Also:

VariableValue.updateRepresentation(javax.swing.JComponent)

rangeVal

public Object rangeVal()

Specified by:

rangeVal in class VariableValue

actionPerformed

public void actionPerformed(ActionEvent e)

ActionListener implementations

Specified by:

actionPerformed in interface ActionListener

focusGained

public void focusGained(FocusEvent e)

FocusListener implementations

Specified by:

focusGained in interface FocusListener

focusLost

public void focusLost(FocusEvent e)

Specified by:

focusLost in interface FocusListener

getValueString

public String getValueString()

Specified by:

getValueString in class VariableValue

Returns:

String that can (usually) be interpreted as an integer

setIntValue

public void setIntValue(int i)

Description copied from class: VariableValue

Set the value from a single number. In some cases, e.g. speed tables, this will result in complex behavior, where setIntValue(getIntValue()) results in something unexpected.

Specified by:

setIntValue in class VariableValue

getIntValue

public int getIntValue()

Description copied from class: VariableValue

Get the value as a single number. In some cases, e.g. speed tables, this will result in complex behavior, where setIntValue(getIntValue()) results in something unexpected.
