Interface Manipulating2D

All Known Implementing Classes:
  Display2D

    public interface Manipulating2D

Manipulating2D is a simple interface for user interface objects which can manipulate portrayals in certain ways. The primary function of the Manipulating2D interface is to pass Display2D etc. through to SimplePortrayal2D subclasses which implement the handleMouseEvent(...) method without providing them an explicit class like Display2D. Some of these classes (notably MovablePortrayal2D) need a few Display2D functions to do their dirty work, which is where the Manipulating interface comes in. Eventually as we determine that more Display2D features need to be made available to certain SimplePortrayal2D subclasses, we may extend this interface.
