xview_scroll ( number, what )yview()yview_moveto ( fraction )Scrolls the listbox horizontally. For the what argument, use either UNITS to scrollby characters, or PAGES to scroll by pages, that is, by the width of the listbox.The number argument tells how many to scroll.To make the listbox vertically scrollable, set the command option of theassociated vertical scrollbar to this method.Scroll the listbox so that the top fraction of the width of its longest line is outsidethe left side of the listbox. Fraction is in the range [0,1].yview_scroll ( number, what )Example: Try the following example yourself:from Tkinter import *import tkMessageBoximport Tkintertop = Tk()Lb1 = Listbox(top)Lb1.insert(1, "Python")Lb1.insert(2, "Perl")Lb1.insert(3, "C")Lb1.insert(4, "PHP")Lb1.insert(5, "JSP")Lb1.insert(6, "Ruby")Lb1.pack()top.mainloop()Scrolls the listbox vertically. For the what argument, use either UNITS to scroll bylines, or PAGES to scroll by pages, that is, by the height of the listbox. Thenumber argument tells how many to scroll.When the above code is executed, it produces the following result:Menubutton A menubutton is the part of a drop-down menu that stays on the screen all the time.
