It's built into the FloatCanvas events:
Canvas.Bind(FloatCanvas.EVT_LEFT_DOWN, self.OnLeft)
def OnLeft(self, event):
print "world coords are:", event.Coords
print "pixel coords are:", event.GetPosition()
There is a full set of FloatCanvas events.
By the way, if you do have a reason to convert from pixel to world
coords, there is:
FloatCanvas.PixelToWorld()
and
FloatCanvas.WorldToPixel()
I wish I'd documented all this more, but do make sure to poke around the
demos and the source -- it's all there somewhere.
