This is what I want to do...almost:
-----
#! /usr/bin/env python
from Tkinter import *
Root = Tk()
RowActiveVar = StringVar()
LastWidth = 0
Count = 0
def iChanged(e = None):
global LastWidth
global Count
Count += 1
Geom = Root.geometry()
Width = int(Geom[:Geom.index("x")])
if Width == LastWidth:
return
# Root.geometry("%d%s"%((Width+ScrollWidth+2), Geom[Geom.index("x"):]))
LastWidth = Width+ScrollWidth+2
return
RowSub = Frame(Root, bg = "blue")
RowCan = Canvas(RowSub, bg = "red")
RowCan.pack(side = LEFT, expand = YES, fill = BOTH)
Scroll = Scrollbar(RowSub, orient = VERTICAL, command = RowCan.yview, \
width = 15)
Scroll.pack(side = RIGHT, fill = Y)
ScrollWidth = int(Scroll.cget("width"))+int(Scroll.cget("bd"))*2+ \
int(Scroll.cget("highlightthickness"))*2
RowCan.configure(yscrollcommand = Scroll.set)
RowSub.pack(side = TOP, expand = YES, fill = BOTH)
Y = 0
for I in xrange(1, 20):
SSub = Frame()
LRb = Radiobutton(SSub, text = "", variable = RowActiveVar, \
value = str(I), bg = Frame().cget("bg"))
LRb.pack(side = LEFT)
LEnt = Entry(SSub, width = 15, bg = "white")
LEnt.pack(side = LEFT)
# This one...
LEnt = Entry(SSub, width = 40, bg = "white")
LEnt.pack(side = LEFT, expand = YES, fill = X)
LEnt = Entry(SSub, width = 10, bg = "white")
LEnt.pack(side = LEFT)
SSub.pack(expand = YES, fill = X)
RowCan.create_window(0, Y, anchor = "nw", window = SSub)
RowCan.update()
L,T,R,B = RowCan.bbox(ALL)
Y = B
RowCan.configure(scrollregion = (0, 0, R, B))
Geom = Root.geometry()
LastWidth = R+ScrollWidth+2
Root.geometry("%d%s"%(LastWidth, Geom[Geom.index("x"):]))
Root.bind("<Configure>", iChanged)
Root.mainloop()

I'd like the center column of Entry fields to get longer as the window width is
changed. I have a static non-scrollbar version of this that works fine (Entry
fields in a Frame that is packed TOP into another Frame -- everyone set to
expand and fill as needed), but throwing the Canvas and the scrolling in there
seems to be a problem. I have another version that uses a Text() to hold all
of the rows, but I can't get that to work either. The iChanged() stuff really
doesn't do anything at this point. I was thinking that might be where a
solution goes. Can it be done?
Thanks!
Bob
