Class ScaleViewer

Object
  ScaleViewer

public class ScaleViewer
extends Object

Allows editing/viewing of a scale. Used to build the min/max scale editors for a rule.

Here is the pretty picture:

          +-+ +-------------+             
    Scale:|x| | 90%       \/| 
          +-+ +-------------+
 

Workflow:

1. createControl( parent ) - set up controls
2. setFill( stroke, mode ) - provide content from SimpleStyleConfigurator/SimpleRasterConfigurator
   1. scale values got from rules
   2. values copied into controls
   3. controls enabled based on mode & fields
3. Listener.widgetSelected/modifyText - User performs an "edit"
4. Listener.sync( SelectionEvent ) - update fields with values of controls
5. fire( SelectionSevent ) - notify SimpleStyleConfigurator/SimpleRasterConfigurator of change
6. getScale( ) - returns the specified scale
