How do I link a listbox and radio button to push button?

How do I link a listbox and radio button to push button? I want one pushbutton to call both the listbox and the radio button at the same time.

You can just call each respective callback from the pushbutton callback function. Also, do you really need parallel execution? Because that can be very difficult, if not impossible.

I could actually do it using the if condition but thanks for the reply
