Flowgraph reading keystrokes during execution

GNU Radio
1

Dear Sir,

I am thinking of building simple chat application using gnuradio.
PC#1 connecting to USRP#1, will send text message to PC#2 via USRP#2.
The question is, how to get the user keystrokes from the flowgraph at
PC#1 ?

I am building the flowgraphs using GRC (Companion).
I guess I need to use something similar to WX GUI Slider, that get the
user keystrokes instead of the slider position, into the flowgraph,
during its execution.

Thanks in advance.

Sure, you can add another widget to do that. You probably want to catch
an event from QT and turn that into a message, then post that
asynchronously.
