public class TLcdGXYFeaturedPolygonLabelPainter
extends TLcdGXYPolygonLabelPainter
implements ILcdGXYLabelPainter
```
Extension of TLcdGXYPolygonLabelPainter that retrieves the label content through the ILcdFeatured interface instead of using object.toString().
It therefore assumes that the object to paint (given in TLcdGXYPolygonLabelPainter.setObject(Object)) implements the ILcdFeatured interface (note that the superclass imposes some more restrictions). In order to build the label content (see retrieveLabels), it then retrieves the feature values (see ILcdFeatured.getFeature(int)) corresponding to the feature indices specified using setFeatureIndices(int[]).
Note that, because this painter uses the same list of indices for all objects, it cannot be used if all the ILcdFeatured objects have different feature counts. In that case, it is advised to tailor retrieveLabels(int, ILcdGXYContext) to the specific needs.

    Deprecated. this is controller logic. Use TLcdGXYInteractiveLabelsController instead.
    
    Sets the interactive label provider. This method can be called at most once. If the interactive label provider was previously set (with this method or in the constructor), calling this method will throw and IllegalStateException.
    Note that to fully enable the functionality, setProvideInteractiveLabelOnMouseOver must be set to true.
    
    Parameters:
    
    aGXYInteractiveLabelProvider - The interactive label provider that will be used to configure and show a component that can, for instance, be used to edit the properties of the labeled domain object. This cannot be null.
    
    Throws:
    
    IllegalStateException - When the interactive label provider was already set.
    
    IllegalArgumentException - When the interactive label provider was null.

  - getComponentForGXYView
```
protected Component getComponentForGXYView(ILcdGXYView aGXYView)
```
    Gets the component that represents the given ILcdGXYView. By default this is the view itself casted to java.awt.Component. This information is used for handling mouse events.
    
    Override this method if your ILcdGXYView implementation does not extend from java.awt.Component.
    
    Parameters:
    
    aGXYView - The view for which a Component must be retrieved.
    
    Returns:
    
    The java.awt.Component which corresponds to the given ILcdGXYView
    
    Throws:
    
    IllegalArgumentException - By default when aGXYView is not a java.awt.Component

  - canAddComponentToGXYView
```
protected boolean canAddComponentToGXYView(ILcdGXYView aGXYView)
```
    Returns whether or not an interactive label can be added to the given view. If this method returns false, addComponentToGXYView must not be called. By default this method checks if the given ILcdGXYView is an instance of java.awt.Container without a layout set on it.
    
    Override this method if your ILcdGXYView implementation is not a java.awt.Container or if you add components to another container than the specified ILcdGXYView.
    
    Parameters:
    
    aGXYView - The ILcdGXYView for which to check if a component can be added.
    
    Returns:

                                     Component aComponent)
```
    Adds the specified interactive label to the user interface. By default this method casts the given ILcdGXYView to java.awt.Container and adds the component to the view.
    
    Override this method if your implementation of ILcdGXYView does not extend from java.awt.Container or if you want to add the interactive label to another java.awt.Container because, for instance, you already need to add other components to the specified ILcdGXYView.
    
    If you override this method, you also need to override canAddComponentToGXYView and removeComponentFromGXYView as these methods are closely related to each other.
    
    This method will not be called if canAddComponentToGXYView returns false.
    
    Parameters:
    
    aGXYView - The view to which the interactive label should be added.
    
    aComponent - The interactive label that should be added to the user interface.
    
    Throws:
    
    IllegalArgumentException - By default if aGXYView is not an instance of java.awt.Container or if the layout of aGXYView is not null.

```
    Description copied from interface: ILcdGXYLabelPainter2
    
    Tests if the label specified by setObject, setLabelIndex and setSubLabelIndex is touched at view location (specified by aGXYContext.getX() and aGXYContext.getY()), considering the mode and the ILcdGXYContext instance.
    Before calling this method, the domain object, the label index, the sublabel index and the location of the label should be set using the respective methods.
    
    Specified by:
    
    isLabelTouched in interface ILcdGXYLabelPainter2
    
    Parameters:
    
    aGraphics - The Graphics instance on which the label is painted.
    
    aMode - the mode to consider. This is a bitwise combinations of several constants. See ILcdGXYLabelPainter2.paintLabel(java.awt.Graphics, int, com.luciad.view.gxy.ILcdGXYContext) for more information.
    
    aGXYContext - the ILcdGXYContext to consider.

                          throws TLcdNoBoundsException
```
    Description copied from interface: ILcdGXYLabelPainter2
    
    Sets aPointSFCT to the anchor point of the label specified by setObject, setLabelIndex and setSubLabelIndex.
    If the location index is less than 0, the label anchor point is unambiguously determined by the label location. The actual label is to be painted somewhere around this anchor point. This method is typically called to compare the result with the label bounds, thus determining the exact relation between the label and its location.
    Before calling this method, the domain object, the label index, the sublabel index and the location of the label should be set using the respective methods.
    
    Specified by:
    
    labelAnchorPointSFCT in interface ILcdGXYLabelPainter2
    
    Parameters:
    
    aGraphics - The Graphics instance on which the label is painted.
    
    aMode - The mode to consider. This can be a bitwise combination of several constants. See ILcdGXYLabelPainter2.paintLabel(java.awt.Graphics, int, com.luciad.view.gxy.ILcdGXYContext) for more information.
    
    aGXYContext - The ILcdGXYContext that can be used to retrieve extra information.
    
    aPointSFCT - The point which will be updated to reflect the location of the anchor point.
    
    Throws:
    
    TLcdNoBoundsException - if the Object doesn't have any valid anchor point, e.g. if it is always invisible in the current projection.

```
 public ILcdGXYLabelPainter getGXYLabelPainter(Object aObject) {
   ILcdGXYLabelPainter labelPainter = ... // find the label painter for the object
   if (labelPainter != null) {
    labelPainter.setObject(aObject);
