NumericTextLine

Input or output of a numeric value including a short textual description. Often several NumericTextLines are stacked vertically (f.i. in a ComputeSheet). In this case the positions of the text fields can be aligned.
In addition to the usual PropertyChange a VetoableChange can be used. This allows to check whether the entered value is acceptable and to reject the change if it isn't.

Properties:

• double value	(initial) numeric value
  String title	textual description of the value
  String description	short description of the value, usually just the symbol
  String unit	unit text of the value
  int precision	number of decimals shown in the text field
  int columns	width of text field showing the value
  boolean editable	if false, the value cannot be edited (output field)
  int offset	right offset of the text field, used for alignment

Events:

• PropertyChange	change of value
  VetoableChange	change of value that may be rejected
