I am writing a Weight converter to convert killogram to Pounds and vice versa.... Using QT Desginer I have done the interface etc, but now I am stuck trying to figure out how to link the buttons so that when you press one it converts to pound what is entered and vice versa...

  • Why don't you pear down the interface to something much simpler first to learn how it works, then come back with questions when you have something more specific than *"how do I do it?"* – Aaron Apr 10 '17 at 18:17
  • For example: create an interface with a single button that has a callback that simply prints "hello world" to the console using `print('hello world')` – Aaron Apr 10 '17 at 18:18
  • Wish i had time to... the assignment was moved up to tonight.... – PJ Pierre Nothnagel Apr 10 '17 at 18:20
  • If eyllanesc's answer doesn't do it for you I would reccomend using `tkinter` over Qt. It's very well documented, and is imao simpler to understand and get into using. – Aaron Apr 10 '17 at 18:28
