InstrumentKit | Python package for interacting with laboratory equipment

I am trying to make a user interface for a SRS DG645. I'm very new to PyQt5 (and let's face the truth - I am also very fresh with Python), and I was trying to do a small test menu to try and get some functionality - and understand how this works.

I was sucessfully able to initiate and close connection to the intrument via the 'Initialize' and 'Close' buttons.

What I wanted to do next was to be able to set delays. For that, I created two entrys - entry1 and entry2 - which would provide the 'channel' (an integer) and the 'timing' (a float).

For the script to work, I need to associate the 'Write Values' button with the a function which was described previously in the file - set_delay() - which requires a tuple of (channel,timing) in order to be sucessfully executed.

I am completely oblivious on how to implement the code for this button, as I don't understand how I can get the arguments passed by the entry boxes and insert them into the required dg.set_value() function.

I am aware of this answer: How to pass arguments to functions by the click of button in PyQt? by I believe it does not fully answer my present question

Any help would be greatly appreciated!

PS: A big thank you to Trappisch and Casagrande for making their code public in Git!

Please find below the MWE for my implementation
