Bug 126527 [Field Assist] - API - Field Decoration alignment issues are different for cell editors
bundles/org.eclipse.jface/src/org/eclipse/jface/fieldassist/DecoratedTextCellEditor.java
import org.eclipse.swt.widgets.Text;
/**
 * A cell editor that manages a text entry field, but creates it inside a
 * DecoratedField so that clients can install decorations. Copied from
 * TextCellEditor revision 1.17 and modified in the following ways:
 * </p>
 * <ul>
 * <li>creates a DecoratedField with an inner text control instead of creating
 * a text control.</li>
 * <li>makes the decorated field available via API for installing decorations</li>
 * <li>makes the text control available via API for installing a content
 * proposal adapter on it.</li>
 * </ul>
 * <p>
 * Changes to the original methods are marked with 
 * and .
 * </p>
 * 
 * This class may be instantiated; it is not intended to be subclassed.
 * </p>
 * 
 * <p>
 * This API is considered experimental. It is still evolving during 3.2 and is
 * subject to change. It is being released to obtain feedback from early
 * adopters.
 * </p>
 * 
 * @since 3.2
