Re: [Discuss-gnuradio] Custom gnuradio GUI for OOT blocks

Thank you very much Marcus, I do appreciate your help, I only have experience with GUIs in android .

The big picture is to change the behavior of the OOT blocks based on the user input; and the user interacts with the system using widgets (buttons, edit texts, etc)

You were right, I don't need to recompile the C++ code, I didn't think it properly.

To give you an example of what I want to do, let's say I have a transmit block named myBlock (oot block, c++), which has a function f, and that function, has a parameter int n.

Then, I have a main.py file, which launches the application (consisting of several connected blocks), with a declaration of that block

self.myBlock = myModule.myBlock()

I want to launch the main.py using a GUI by pressing a button, and selecting the parameters of the function f. These parameters should be selected with widgets (buttons or some other)

Also, which widgets are possible to use? (buttons, editText, etc)

I looked at the documentation, but it is only about blocks for plotting

Hi Laura,

first: Don't use WX. It's dead, and we've deleted the code from the
coming releases. Use Qt, we support it well.

Why do you need to *recompile* C++ code through the GUI? That sounds
architecturally more than questionable. It also contradicts what you
say: you just want to call C++ functions from your GUI. But maybe I'm
missing something here; if so, please elaborate!

The latter is actually not that hard – assuming your functions are
callable from Python (and our build system takes care of that!), you
can just use them as Qt "SLOT"s, which means that you can connect an
event (e.g. a button click) to them in Python.

So, you'd need no extra framework at all – GNU Radio and our python
wrappers and Qt do all this for you :)

Best regards,
Marcus
