java.lang.Object |
getConstraintFor(Point p)
Returns a Rectangle at the given Point with width and height of -1. |
java.lang.Object |
getConstraintFor(Rectangle r)
Returns a new Rectangle equivalent to the passed Rectangle. |
protected java.lang.Object |
getConstraintFor(Request request,
GraphicalEditPart child,
Rectangle rect)
Overridden to preserve existing width and height (as well as preferred sizes) during MOVE requests. |
protected Rectangle |
getCurrentConstraintFor(GraphicalEditPart child)
Retrieves the child's current constraint from the LayoutManager . |
protected Point |
getLayoutOrigin()
Returns XYLayout.getOrigin(IFigure) . |
protected Dimension |
getMinimumSizeFor(GraphicalEditPart child)
Deprecated. Clients should no longer extend this method. Instead, the resize tracker, constructed by the 'satellite' primary drag edit policy should be parameterized with max and min size constraints. |

showSizeOnDropFeedback(CreateRequest request)
Shows size-on-drop feedback during creation. |
