That is, a QTDisplaySpace is some kind of QTDrawable so can be set as a client for a QTCanvas. <P> As a display space is by definition a collection of objects that have some kind of visual appearance, the display space must manage (or its contained objects) the layering of those objects within the visual presentation of the space. As such, this interface provides an API for retrieving the current front and back most layers of its members, and a way of retrieving the Layerable object for a member that allow the member to both get and set its Layer within the display space. Also a member can be added to the display space specifying the layer at which it should be added. The lower a layer (or z) value the more frontmost the object is displayed at. The backmost layer of a QTDisplaySpace is Short.MAX_VALUE. <P> Members of display spaces may or may not know about their position and two Dimensional display matrix. As such the QTDisplaySpace also provides an API for retrieving a member's Transformable interface that allows a member to get and set its display matrix.<P><DL><DT><B>See Also: </B><DD><A
