I am trying to poll selections from a listbox but can't seem to get it
to work correctly.
class pollstuff:
def __init__(self, master):
self.listbox = Listbox(master)
self.listbox.pa ck()
names = ['Bob', 'Neal', 'Mike']
for n in names:
self.listbox.in sert(END, n)
self.listbox.se lect_set(0)
LabelStr = StringVar()
self.label = Label(master, textvariable=La belStr)
self.label.pack ()
LabelStr.set(na mes[map(int, self.listbox.cu rselection())])
root = Tk()
app = pollstuff(root)
root.mainloop()
Obviously when this starts up this is going to show selection #0 inside
the label box. How do I make sure that whatever is arbitrarily selected
ends up in the label box as this gui runs? I tried doing a bind:
self.listbox.bi nd("<Button-1>", self.changelabe l)
This did not work as intended as the changelabel's text option only
showed what the selection index was BEFORE the event took place. Does
anyone know of any special thing I need to do in order to poll the
listbox items?
Thanks,
Harlin 1 1903

Bind on <ButtonReleas e-1>; <Button-1> is a synonym for <ButtonPress-1>, and when the button is pressed, the selection is not done yet.

Hello,
Is there a quick way to replace the content of a single item in
tkinter's listbox? Currently my solution is to first delete the item,
then insert a new item at the same position. I think there may be
better way.

Whenever I set up something similar:
vals =
for v in vals:
listbox.inset(END, v)
I notice that when this listbox is displayed, there is never a default
value. How can I make sure that one of the indices is selected by
default?

I'm trying to implement multiple selection functionality in a Tix Hlist
using a control-click. I've bound control-click to a function that uses

Only the last clicked item appears selected (highlighted) in the

2 items, rather than all the items I have control-clicked.
It's odd, because if I set up the...

I'm working on a Windows applicaton with VS 2003 on windows 2000. I have a

listbox display 2 columns information from the dataset and how can I do that?
Also, I set the property of the listbox to selectionmode...

Hi,
I have a odd but a known question about listbox. I know listbox
control can provide multi-select, multi-extendend selections. But i
wonder if this selection type belongs to them or it has another
tecnique.
As you may know, in softwares like Windows Media Player or Winamp
playlist has a listbox and it can be selected in 2 types. First type
refers to player's own selection and second selection type can be done

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
