public class JSimpleStyleDialog extends JDialog
A dialog to prompt the user for feature style choices. It has a number of static showDialog methods to work with different sources (SimpleFeatureType, Layer, DataStore). Each of these displays a dialog and then creates a new Style instance.

Examples of use: 


 // Use with a shapefile
 Component parentGUIComponent = null;
 ShapefileDataStore shapefile = ...
 Style style = JSimpleStyleDialog.showDialog(parentGUIComponent, shapefile);
 if (style != null) {
    // create a layer using this style
 }

 // Use with an existing Layer
 Layer layer = ...
 Style style = JSimpleStyleDialog.showDialog(parentGUIComponent, layer);
 if (style != null) {
     layer.setStyle( style );
 }
