Folks,
I am trying to implement a GUI frontend for the little Softrock40 board
from amqrp. I have a very primitive but usable radio up and running.
This is what I am trying to do. On the click of a button, the user
should be able to switch from a FFT view to waterfall view. To do this,
I stopped the flow_graph, disconnected the waterfall block and connect
FFT block (or vice-versa), and start the flow_graph again. But the
problem is that the block disconnected remain dangling and has to be
distroyed completely from the instance, otherwise it gives an error.
This is what I am trying. I need to change it to use the new fftsink
usage. Any idea how to fix this?
def OnFFTButton(self, event):
self.stop ()
self.disconnect (self.f2c, self.waterfall_block)
self.fft_block, self.fft_win = fftsink.make_fft_sink_c (self, self.panel,
"Softrock40", 1024, self.sampling_freq, -100)
self.vbox.Add (self.fft_win, 10, wx.EXPAND)
self.waterfall_block = None
self.connect (self.f2c, self.fft_block)
self.start ()
