I'm creating a program which displays spreadsheet-like data using
hundreds of labels. At first this works fine, however after a few
redisplays it starts slowing down dramatically.
A small test program, without the distractions of the real program is:
from Tkinter import *
def Go():
LabelList = []
for J in range(30):
print J
for L in LabelList: L.grid_forget()
LabelList = []
for Row in range(20):
for Col in range(20):
L = Label(r,text='%s'%J)
L.grid(row=Row,column=Col)
LabelList.append(L)
r.update_idletasks()
r = Tk()
r.after(1000,Go)
r.geometry('800x600')
r.mainloop()
This runs quickly at first but gradually slows down to a crawl during
the latter iterations. Anyone have any idea what is causing this to go
slow or how I could speed it up? I'm running Python 2.4.3 on an Ubuntu
6.06 system.
Thanks
Cam Farnell
