How to create a new QT GUI SINK

GNU Radio

Hi all,

I need to create a new QT GUI SINK with aditional buttons, i found the
blocks structure in the repository (
http://gnuradio.org/redmine/projects/gnuradio/repository/revisions/master/show/gr-qtgui),
but i don’t know where is it on my gnuradio installation.

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?

Thank you very much.

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

etc.

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
