GNU Radio

Hi All

kindly clarify my query on using wxgui of gnuradio to embedd it into
another application …

I have a necessity to integrate the qtgui window to a parent Qt
Application.Please let me know if i use the existing function

qtgui.sink_c (int fftsize, int wintype, double fc=0,
double bandwidth=1.0, const std::string &name=“Spectrum Display”,
bool plotfreq=true, bool plotwaterfall=true, bool
plotwaterfall3d=true, bool plottime=true, bool
plotconst=true, bool use_openGL=true, QWidget
*parent=NULL)

how to use the argument parent pointer highlighted .

If it helps, you can use gnuradio-companion to generate a pyqt
application with this qtgui sink. Use the generated python code as an
example. See the Generate Options in the options block and the QT GUI
Widgets category in the block tree.

There’s some confusion with your email in mixing the wxgui and qtgui
blocks. I’m not sure the two mix.

But if you are focused only on the qtgui applications and using it as
part
of a larger Qt project, then you should be able to do this. A good place
to
start is gr-qtgui/apps/qt_digital.py. I embed two qtgui sinks into a
larger
project. I don’t use the parent widget, though I probably could have.

Note that this app was written all in Python using PyQT. I’m not sure
how
easy you’ll find it to work with the qtgui in a pure C++ environment;
I’ve
never tried and it wasn’t designed with that in mind, initially. But the
qt_digital.py is still a good place to start for what you are asking
about.
