can i make a copy of the structure and modify it ?
if i do it, is it necessary to re-build gnuradio?
is there another way to do and new QT GUI SINK?

Well, if your source code tree starts in gnuradio, you'll find the qt-gui stuff in gnuradio/gr-qtgui.

c++ code in lib
xml definition for grc in grc


If you only want to add gui elements to an existing sink, it might be possible to modify the existing code, recompile and install.

But you can build your own module, too.But you have to consider some qt programming rules. You can find an example of an 'qt-gui picture sink' to display noaa pictures on
