Rogue Wave® JViews graphic
objects inherit attributes from the
IlvGraphic abstract base class. This class allows a Rogue Wave JViews graphic object to draw itself at a
given destination port.If required, the coordinates of the graphic
object may also be transformed by an object associated with the
IlvTransformer
class.
The class IlvGraphic
has methods
that allow you to set and change geometric dimensions but does not
actually implement these methods. They are declared as nonfinal methods
and are defined to perform various operations in the classes that
inherit IlvGraphic
attributes. Although
the methods to manipulate geometric shapes and graphic attributes
exist, their implementations are empty. Several methods are given
to set and get user properties that can be associated with an object
for application-specific purposes.
