code execution after event - shift838 - Nov-25-2018
i am very new to Python. I'm a .NET programmer but want to get into Python so I can write cross-platform code that will work on Windows as well as Linux based OS'.
I have coded a GUI python form for some testing with various buttons, combo boxes and check buttons.
I want to be able to execute specific code say if a button is selected or a value is selected.
Can someone point me to somewhere to read up on how to do this or give me some direction.
Thank you,

Although this document is rather old, It's still the best (In my opinion) tkinter reference: http://infohost.nmt.edu/tcc/help/pubs/tkinter/web/index.html pdf version: http://www.nmt.edu/tcc/help/pubs/tkinter/tkinter.pdf.
There's also now: https://docs.python.org/3/library/tk.html which I haven't really reviewed, but looks to be very complete, and what's more, new. Looks like it might be a better choice.
As far as executing specific code when a button is pushed, you need to look up event processing. There are a couple of ways of doing it, simplest is using control in the Button definition, most powerful is by using bind: http://infohost.nmt.edu/tcc/help/pubs/tkinter/web/events.html or https://docs.python.org/3/library/tkinter.html#bindings-and-events .
You can use lambda on the control version to add arguments, but bind still provides more flexibility.
