I'm new to this place and tkinter. I am stuck at making a scrollable listbox or canvas. I have tried both widgets. Within this listbox or canvas, I have several entry and label widgets. The origin point is R0,C0. I used row/columnconfigure to stretch the listbox or canvas.
In the main window, I had 4 buttons on row four to column four (0,4->4,4). I placed the scrollbar on column 5. I attempted to use the grid method. The issue I am having is making the scrollbar functional.
Note: Turning the mainframe into a class is only one of the ways I have tried. Packing the scrollbar on the right has worked, with the listbox/canvas packed on the left. However, the listbox/canvas widget that the scrollbar is commanded to does not scroll the listbox/canvas. Also, adding many entry boxes does not cause the listbox/canvas to scroll. Help please.

Style().configure("B.TFrame", relief="flat",
background="blue")
Style().configure("R.TFrame", relief="flat",
background="red")
Style().configure("R.TLabel", background="red")
class Application(Frame):
def __init__(self, master=None):
Frame.__init__(self, master, style="B.TFrame")
self.grid(sticky=N+S+E+W)
self.mainframe()
def mainframe(self):
top=self.winfo_toplevel()
self.menuBar = Menu(top)
top["menu"] = self.menuBar
self.subMenu = Menu(self.menuBar, tearoff=0)
self.subMenu2 = Menu(self.menuBar, tearoff=0)
self.menuBar.add_cascade(label="File", menu=self.subMenu)
self.menuBar.add_cascade(label="About", menu=self.subMenu2)
self.subMenu.add_command(label="Open")
self.subMenu.add_command(label="Save")
self.subMenu.add_command(label="Exit")
self.subMenu2.add_command(label="About")
self.subMenu2.add_command(label="Help")
self.data = Listbox (self, bg='red')
scrollbar = Scrollbar(self.data, orient=VERTICAL)
self.add = Button(self, text="")
self.remove = Button(self, text="")
self.run = Button(self, text="")
self.stop = Button(self, text="")
self.data.grid (row=0, column=0, rowspan=4, columnspan=4, sticky=N+E+S+W)
self.data.columnconfigure(1, weight=1)
self.data.columnconfigure(3, weight=1)
self.add.grid(row=4,column=0,sticky=EW)
self.remove.grid(row=4,column=1,sticky=EW)
self.run.grid(row=4,column=2,sticky=EW)
self.stop.grid(row=4,column=3,sticky=EW)
scrollbar.grid(column=5, sticky=N+S)

Without any content in the listbox, there's nothing to scroll...
This seems to work though (shortened the example a bit). See also the example at the scrollbar documentation.
