python TK scrollbar problem

[Ray]

Hi,

would someone tell me how to make scrollbar work under grid?
I think I'm missing something to connect scrollbar with the grid.
following is some sample code. it shows the scrollbar, but it do not work.

Thanks a lot for the help!

#####code begin########
from Tkinter import *
def mygrid(text,M = []):
while M:
x = M.pop()
x.destroy()
rows = []
count=int(text)
yscroll = Scrollbar(frame_grid, orient='vertical')
yscroll.grid(rowspan=count, column=5, sticky=NS)
M.append(yscroll)
for i in range(count):
cols = []
for j in range(4):
e = Entry(frame_grid, relief=RIDGE)
M.append(e)
e.grid(row=i, column=j, sticky=NSEW)
e.insert(END, '%d.%d' % (i, j))
cols.append(e)
rows.append(cols)

root=Tk()
frame_entry=Frame(root, width=550, height=100)
frame_entry.pack()
text=Entry(frame_entry)
text.pack(side=LEFT)
button=Button(frame_entry, text='generate grid',
command=(lambda:mygrid(text.get())))
button.pack()
frame_space=Frame(root, width=550, height=100)
frame_space.pack()
frame_grid=Frame(root, width=550, height=300, relief=GROOVE)
frame_grid.pack()
frame_exit=Frame(root, width=550, height=100)
frame_exit.pack()
button2=Button(frame_exit, text='exit', command=root.quit)
button2.pack()
root.mainloop()

You are not binding to the Scrollbar.set() method nor are you assigning
the Scrollbar a command. You should try to emulate this:

http://www.pythonware.com/library/tkinter/introduction/x7583-patterns.htm

You need to also determine exactly what it is you want to scroll. You
probably don't want to scroll frame_grid as that contains your
scrollbar. Google "tkinter scrolled frame". Here is an example:

http://mail.python.org/pipermail/python-list/2007-February/427886.html

So, a suggestion would be to create a new frame to hold frame_grid and
yscroll and then use yscroll to scroll frame_grid.
