public class IlvDrawSelection extends IlvHandlesSelection
IlvDrawSelection
class is the default
selection object for graphic objects.
This class draws eight handles around the bounding
rectangle of an object to show that it is selected.
There are four handles on each corner of the bounding rectangle
and four handles in the middle of each side.
The interactor allows you to reshape the object by
dragging a handle, unless the method supportsResize()
returns false

The method can be overridden by subclasses to indicate that the base
rectangle of the handles must be different from the
bounding box of the object. If the rectangle returned
by the overridden implementation does not completely contain
the bounding box of the object, the method isOptimizedDrawingEnabled()
must also be overridden to return always false
.

true
if the drawing optimization is enabled for
the selected graphic object. Returns false
otherwise.
The default implementation returns always true
.
The method must be overridden to return always false
if
the method getHandlesRectangle(ilog.views.IlvTransformer)
is overridden and returns
a rectangle which does not completely contain the bounding box
of the selected object.
isOptimizedDrawingEnabled

public boolean supportsResize()
true
if this object allows resizing
of the selected graphic object. Returns false
otherwise.
The default implementation always returns true
.
Subclasses can override this method to deal with unresizeable
graphic objects.
