public final class GraphicalFeedbackChildEditPolicy extends org.eclipse.gef.editpolicies.ResizableEditPolicy
Provides support for selecting, positioning, and resizing an editpart. By default, selection is indicated via eight square handles along the editpart's figure, and a rectangular handle that outlines the editpart with a 1-pixel black line. The eight square handles will resize the current selection in the eight primary directions. The rectangular handle will drag the current selection using a DragEditPartsTracker.

By default, during feedback, a rectangle filled using XOR and outlined with dashes is drawn. This feedback can be tailored by contributing a IGraphicalFeedbackFactory via the extension point org.csstudio.sds.graphicalFeedbackFactories.
