You first need a file sink block capable of doing this. I would probably make a file sink that can take in a message to start and stop recording. Then, just have a QT GUI widget send the appropriate message. It's possible you may be able to do this with
a tagged file sink/ existing components, but I'd have to think a bit more on that.
I don't see any reason why it's not possible.

Hi,
I wonder if it’s possible to enable/disable the file sink in GUI, i.e. essentially start/stop file saving after running the flowgraph in GUI by an input from the user (e.g. click of a button)?
Thanks a lot!
