PolygonEdit CanvasItemIF CompositeItem gutz::Counted TFBoxItem List of all members.

Detailed Description

TFItem, generic base class, see TFItemSTD for some concrete example implementations.

This is the generic tf item that the TFView will see, for the most part all external interactions are through the TFItemVec. TFItems are the bridge between simianlib TFElements and the QT interface. An items behavior should be defined by the Element they represent, the Item's role is to comunicate changes to element and display them from the element. You should endevor to make sure "behavior" resides in the simianlib Element and only "interaction" and "display" stuff live in the Item.
