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

[James Cooley]

This sort of code worked for me:

       hbox = wx.BoxSizer (wx.HORIZONTAL)
  
       btn = wx.Button(self.panel, 1001, "STOP", style=wx.BU_EXACTFIT)
       wx.EVT_BUTTON(self.panel, 1001, self.quit)
       vbox.Add(btn, 0, wx.EXPAND)
