Hi Che, I think you got bit by the "reply to list" non-feature of this list...
>> In ours, we catch the mpl button down event and after establishing a >> hit on the legend do: > > I was using the pick event, not the button down event. How do you > "establish a hit on the legend" in the button down event handler? So, keep in mind that we're using 0.90.1. This was before the nice hit-test routines. We wrote our own hit-test routines loosely based around the "object_picker.py" demo that was current at the time. >> bbox = self._legend.get_window_extent() >> self._dragOffset = (bbox.xmin() - mplEvent.x, bbox.ymin() >> - mplEvent.y) >> >> Then in the mousemove event handler we do: >> >> self._moveLegend(mplEvent.x + self._dragOffset[0], >> mplEvent.y + self._dragOffset[1]) >> >> where self._moveLegend is: >> >> def _moveLegend(self, x, y, autoDraw=True): > > What is the purpose of autoDraw = True? This is something we carry around in our application to limit the number of redraws to reduce flicker. >> height = float(self.figure.bbox.height()) >> width = float(self.figure.bbox.width()) > > Can someone confirm that in the most recent version of mpl, > one can no longer do bbox.height(), but must just do bbox.height ? > (when I do it the first way it says float is not callable). I'm pretty sure this is true. >> dx = x/width >> dy = y/height >> >> # The following two lines are specific to our implementation >> and our internal data classes >> self._legendLocation = (dx, dy) >> self.plot.getLegend().setLocation(self._legendLocation) > > So can I exclude them and still get the legend to move?
