- public class DisplayXPolygon
- extends DisplayXObject
This class is a simple visualization class for polygons
represented by the XPolygon
class of the core
package.
The appeareance of the polygon is highly configurable by the use of
painter classes of the type PolgyonPainter
and
LinePainters
Painters
for the
vertices. The painters are not locally stored - they are stored in the properties.
If a painter is not specified via properties, a new painter of the appropiate type
will be created and stored at the local
properties list of this
object. To use other Painters
defined in properties higher in the hierachy, one has to remove the
automatically created property entries at this
object.

DisplayXPolygon
public DisplayXPolygon(ModelController model)
- Constructs a new DisplayXPolygon and connects it with the given
ModelController
(that must have a XPolygon
object
as source object (model).
- Parameters:
model
- the ModelController
that controls the source.
DisplayXPolygon
public DisplayXPolygon(XPolygon source)
- Constructs a new DisplayXPolygon and connects it with the given
XPolygon
via the construction of a new ModelController
.
- Parameters:
source
- the source object.
recalculate
protected void recalculate(RenderContext context,
PropertyStatusReader properties)
- Forces the
DrawAtom
to recalculate its representation.
This method will only be called, if it became dirty via a call
to the DrawObject.makeDirty(boolean)
method or something has happened, that
causes all DrawAtoms
to recalculate their
representation.
This method should only be called by the render system.
- Overrides:
recalculate
in class DrawObject
- Parameters:
context
- the RenderContext
to useproperties
- the PropertyStatusReader
to use for
reading properties
checkActiveElement
protected void checkActiveElement(java.lang.String element)
- This method is called by
DisplayInteractiveObject.activate()
. It should check, which elements
should be set to which activation level if one does activate the element
with the given name. To specify the activated elements and their activation
levels, call DisplayInteractiveObject.setActiveElement(java.lang.String, byte)
for each element. Overwrite this
method in order to implement element activation correctly.
- Overrides:
checkActiveElement
in class DisplayInteractiveObject
- Parameters:
element
- the element name
createElementTransform
protected ElementTransform createElementTransform()
- Creates a new element transformation object. This method will be called
by
DisplayInteractiveObject.elementTransform()
and should be overwritten by subclasses
in order to support element transformation objects correctly.
- Overrides:
createElementTransform
in class DisplayInteractiveObject
- Returns:
- new element transformation object for
this
DisplayObject.
