[Discuss-gnuradio] trying to add a button...

[mjam01]

Hi guys,

I'm trying to add a button to the tvrx_wfm_rcv_gui.py code with the
following placed under the vbox sliders:


button_freq_up = wx.Button(self, panel, 'FREQ UP')
vbox.Add(button_freq_up, 0, wx.ALL | wx.EXPAND, 5)
self.Bind(wx.EVT_BUTTON, self.set_freq_up, button_freq_up)


I get this error saying a pointer is expected and it's stumped me. Any ideas??!!


Traceback (most recent call last):
  File "./tvrx_nbfm_scanner.py", line 264, in ?
    app = stdgui.stdapp (wfm_rx_graph, "TVRX NBFM RX - M0MIK")
