[Tkinter-discuss] Problems with a scrollbar on a listbox

[Michael O'Donnell]

Alex,

  To link a scroller to a widget, you need to link in both directions:
not only setting the yscrollcommand of the ListBox but also:

        self.urlscrollbar.config(command=self. diclistBox.yview)

Example below:

from Tkinter import *

class ScrolledListBox(Frame):

    def __init__(self, master, items=[], width=24, height=20,
bgcol="white", **keywords):
        Frame.__init__(self, master)
        self.config(bg=bgcol)

        # Scrollbars
        scrollbar = Scrollbar(self, orient=VERTICAL)

        # Create the listbox
        self.table=Listbox(self, yscrollcommand=scrollbar.set, **keywords)
        self.table.config(bg = bgcol, width=width, height=height)
        scrollbar.config(command=self.table.yview)
        scrollbar.pack(side=RIGHT, fill=Y)
        self.table.pack(side=LEFT, fill=BOTH, expand=1)

        # insert the items
        for item in items:
            self.table.insert(END, item)
