Tkinter Problem

[Maboroshi]

Why when I use the sticky command with the grid layout manager won't my
Listbox expand it stays in the center maybe I am missing something but
from every tutorial I see it says to do it this way

I am running Python2.3.4 on winxp I haven't tried it on linux yet

Any Ideas are appreciated

Let me know if I am not being clear enough

Cheers

Andrew


from Tkinter import *


class App(Frame):
def __init__(self, master=None):
Frame.__init__( self, master)
self.grid()
self.createWidg ets()

def createWidgets(s elf):
self.listbox = Listbox(self)
# RIGHT HERE THIS WON'T EXPAND TO FILL
self.listbox.gr id(row=0, column=0, rowspan=3, sticky=N+E+S+W)

self.connect = Button(self, text="Connect")
self.connect.gr id(row=0, column=1)
self.execute = Button(self, text="Execute")
self.execute.gr id(row=1, column=1)
self.disconnect = Button(self, text="Disconnec t")
self.disconnect .grid(row=2, column=1)

self.entry = Entry(self)
self.entry.grid (row=3, column=0, columnspan=2, sticky=E+W)


app = App()
app.master.titl e("MySQL DB Project")
app.master.mins ize(400, 300)
app.mainloop()

Remove
[color=blue]

This means you have an additional grid containing a single control (the
Frame). Use a packer instead and make sure it consumes any extra space:

self.pack(fill= BOTH, expand=True)
[color=blue]

You can configure the cell (0, 0) to consume any extra space:

self.rowconfigu re(0, weight=1)
self.columnconf igure(0, weight=1)
[color=blue]

The Entry and Listbox widgets should grow now as expected. To distribute the
Buttons smoothly, you can either set the weight of columns 1 and 2 or put
all three of them in an extra Frame (which I would prefer).
