Actually, I tried that, and there is a bug -- you need to re-set
self.StartMove after moving the Image. Try this:
def OnMove(self, event):
# Always raise the Move event.
self.Canvas._RaiseMouseEvent(event,FloatCanvas.EVT_FC_MOTION)
if event.Dragging() and event.LeftIsDown() and not
self.StartMove is None:
EndMove = N.array(event.GetPosition())
DiffMove = self.StartMove-EndMove
self.Canvas.MoveImage(DiffMove, 'Pixel')
self.StartMove = EndMove
It works quite well for me. In fact, I guess machines are faster than
when I first started working on this, 'cause I have no problems with it
at all, though I haven't tested on the most complex images yet. I may
make this the default method.
