  83
  84 Model a concrete element on a canvas, implemented as QCanvasItem subclasse.
  85 <p>
  86 The concrete QCanvasItem class type is given as this class parameter (either <a class="el" href="class_q_canvas_polygon.html">QCanvasPolygon</a> or <a class="el" href="class_q_canvas_rectangle.html">QCanvasRectangle</a> for example). This class connect the abstract Qanava <a class="el" href="classqan_1_1can_1_1_item.html">can::Item</a> classe to a concrete QCanvasItem graphical object.<p>
  87 Coherency between the QT interface (methods from QCanvasItem) and the <a class="el" href="classqan_1_1can_1_1_item.html">can::Item</a> one is maintained by <a class="el" href="classqan_1_1can_1_1_item_impl.html">ItemImpl</a>, and the two interfaces can be used simultaneously to move the item or get its position.<p>
