When to use Variable classes? (BooleanVar, DoubleVar, IntVar, StringVar)

Question

Can\'t tkinter.widget.configure(text=\"our text\") be used for all widgets? What is the advantage, or the main purpose of using:

var_cls = tkint         


        

Answer 1

StringVar can be bound to a widget, so you just need to have a handle on the StringVar and you can modify its value and it will update automatically. Otherwise, you would need to keep a handle on the widget itself and handle the event loop stuff etc. Basically you should use StringVar etc. when the value could change. If it's going to be static for certain, you don't need it.
