Hi Jakub,
that's right! When you open the block properties of your FFT block, you will see that the
names of some parameters are underlined: That means they have a method of being updated at
runtime.
However, the window field is not underlined!
You can work around that, though, easily! Set your FFT's window to [] (no windowing), and
do the windowing before:
input ---> multiply const --> FFT -->
where the "constant" of "multiply const" is what you adjust at runtime :)
Best regards,
Marcus

Hi there!
I'm pretty new to gnu radio and this is my first time posting to this mailing
list, so excuse me if my question is nonsensical.
I am trying to switch the window type in FFT block during runtime. I added QT
GUI chooser with window.blackmanharris() etc. options, called it win and I put
the variable name win to the Window parameter of FFT block. On start, it works
perfectly (if I change default value of the chooser and start the flowchart)
but nothing happens if I change value of chooser during runtime. It seems to
me, that FFT initialises window type only on startup and doesn't look at it
during runtime.
Is there any way how to do it?
Thanks for any help
