Re: Changing a QT GUI Range variable from a custom block

If you can send a message from a custom block this might work:

I have done this before in C++ but not in Python.

Dear all,

I want to ask you that is it possible to change a QT GUI Range or Chooser variable from a custom python block?

I have inserted the flowgraph below. I can track the GUI variables by giving their IDs to a constant source, which is then connected to the python block. However, I would also like to adjust LO frequency (lo_freq) in the custom block, I can define one more output but have no idea how that output will affect the QT GUI Range variable..

Regards,

dea
