[Discuss-gnuradio] Creating QT GUI out-of-tree blocks in Python

Hi everybody,

I would like to create out-of-tree modules for the GRC, that show graphical interfaces (GUIs) created with QT. As the purpose of these blocks is mainly for prototyping only, I would like to do everything quickly in Python, without the need of additional C++-files.

Here is what I am able to do:

- I can create OOT modules and blocks and use these in the GRC in connection with build-in blocks.

- I can create QT GUIs with QtDesigner and run those in combination with standalone python gnuradio flowgraphs.

What I would like to do is to use the GRC to combine the pre-installed blocks with my own custom GUI blocks. I only found QT GUI blocks programmed in C++ so far. Does anyone have a python block I can look into and cheat with? I assume I can only run widgets created with QtDesigner and not full MainWindows?

What I have so far is my custom out-of-tree sink block, that I can use in GRC. How can I add the .GUI from QtDesigner to the blocks python code? 

Thanks alot. Your help is very much appreciated.

Greetings,

Rashid
