jpicedt.graphic.model
Interface Element
- All Superinterfaces:
- PicObjectConstants
- All Known Implementing Classes:
- AbstractElement
- public interface Element
- extends PicObjectConstants
An interface for graphic elements that can be added to a Drawing.
A graphic element is basically defined by :
- A set of control-point (sometimes called end-points) that specify their geometry
- An attribute set
- A parent and possibly children once the element has been added to a tree defining a model. This allows us to let the root element only hold state about the tree while still maintaining the ability for a child to retrieve this state at any time through a (possibly recursive) call to getParent.
[todo] add an "apply(Transform t)" method as replacement to "translate()" and "scale()", where Transform may possibly inherit from java.awt.geom.AffineTransform [syd : 5/8/2002]
- Since:
- PicEdt 1.0
