This is my OnMove method:
def OnMove(self, event):
# Allways raise the Move event.
self.Canvas._RaiseMouseEvent(event,FloatCanvas.EVT_FC_MOTION)
if event.Dragging() and event.LeftIsDown() and not
self.StartMove is None:
StartMove = self.StartMove
EndMove = N.array(event.GetPosition())
DiffMove = StartMove-EndMove
if N.sum(DiffMove**2) > 16:
self.Canvas.MoveImage(DiffMove, 'Pixel')
it works, however it is not really fluent; I guess it caused by the
constant updating, hence we need the timer stuff you mentioned.
I'm not really sure how to implement it. It would be nice if I could
just set a flag to enable it :)

I would like to build a block diagram editor with ports and lines
between the blocks. I don't anticipate many objects, so high quality
output with anti aliasing is more important than performance.
Ideally I would also like to load a SVG directly since I find it
easier to draw an image in inkscape than to build my image by hand.
However, I know that is not supported by floatcanvas.
(persistance is not necessary for my project. I will just save the
coordinates of my objects)

Thank you. I know about the google soc; right now I'm waiting for that
to finish to see how floatcanvas turns out.
Will anti aliasing and hit testing work at the same time in the future?
