MENUBUTTON IN TKINTER
In this tutorial we will learn about the menubutton in Tkinter. We will learn about the features and properties of the widget followed by a handy example.
What is Menubutton in Tkinter?
Menu Button in Tkinter is a drop-down menu which is shown to the user when the pulldown menu is activated. The Menubutton displays different choices that the user can select from.
Normally, you won’t use the Menubutton. It is only used when you want to provide a set of options to the user i.e. asking the user for occupation, survey etc. The syntax for using Menubutton is:
menubutton_tk = Menubutton( window, features )
