thank you Tom. I had run the usrp_display.py inside the gr-qtgui, it was very interesting. I see that you doesn't use the wxpyton any more and you use the qtgui isn't it? but I cannot find where it do the inserting data for plotting process. in usrp_fft.py it use the fftsink_nongl.py or fftsink_gl.py for the plotting process right?and fftsink_nongl.py insert the data for plotting in set_data function inside the fft_window class. so in fftsink_nongl.py, I tab the evt.data (inside the set_data function) and manipulate it to do my sensing mechanism. I see that the usrp_display.py call the qtgui.py for the plotting process and I think qtgui.py call it's C++ file for further processes isn't it? so how and where can I can tab the data like evt.data in usrp_display or qtgui? could you please explain a bit on how does usrp_display do the plotting process? thank you very much.
