move() is implemented in the class qtcanvas.QCanvasItem
I checked the pyqt sources and it is linked via sip to the C++ object file.
In C++, QCanvasItem.move is delegated to QCanvasItem.moveBy.
-- snip: C++ sources --
void QCanvasItem::move( double x, double y ){
moveBy( x-myx, y-myy );
}
void QCanvasItem::moveBy( double dx, double dy ){
if ( dx || dy ) {
removeFromChunks();
myx += dx;
myy += dy;
addToChunks();
}
}

>>> import qtcanvas
>>> qtcanvas.QCanvasItem.move
<built-in function move>
Here is a working portion which recreates the strange output:
-- snip --
from qtcanvas import *
class Node(object):
def move(self, x,y):
print "Node: move(%d,%d)"%(x,y)
class Rhomb(QCanvasPolygon, Node):
def __init__(self, parent):
QCanvasPolygon.__init__(self, parent)
Node.__init__(self)
print Rhomb.mro()
r = Rhomb(None)
r.move(1,2)
-- snip --
This prints:
[<class '__main__.Rhomb'>, <class 'qtcanvas.QCanvasPolygon'>, <class
'qtcanvas.QCanvasPolygonalItem'>, <class 'qtcanvas.QCanvasItem'>, <class
'qt.Qt'>, <type 'sip.wrapper'>, <class '__main__.Node'>, <type 'object'>]
Node: move(1,2)
Ciao
