QetGraphicsHandlerItem Class Reference

The QetGraphicsHandlerItem class This graphics item represents a point, destined to be used as an handler, for modifie the geometrie of a another graphics item (like shapes). The graphics item to be modified, must call "installSceneEventFilter" of this item with itself for argument,. The ghraphics item to be modified, need to reimplement "sceneEventFilter" for create the modification behavior. More...
