I have a user who is occasionally getting this:
raceback (most recent call last):
File
"/usr/local/lib/python2.7/dist-packages/gnuradio/wxgui/plotter/common.py",
line 106, in <lambda>
self._plotter.Bind(wx.EVT_LEFT_DOWN, lambda evt:
plotter.call_freq_callback(evt.GetPosition()))
File
"/usr/local/lib/python2.7/dist-packages/gnuradio/wxgui/plotter/grid_plotter_base.py",
line 90, in call_freq_callback
x, y = self._point_label_coordinate
TypeError: 'NoneType' object is not iterable
In the "simple_ra" app, which does establish a call-back for left-clicky
in the spectral window.
Is this perhaps because the callback is getting called at a time when
the plotter isn't fully set up, and how can we detect that case properly?
