Listbox fill=BOTH expand=YES (Tkinter)

[Harlin Seritt]

I am trying the following:

Listbox(parent) .pack(fill=BOTH , expand=YES)

I notice that the listbox will fill on the X axis but will not on the Y
axis unlike other widgets. Is there any way to force this?

thanks,

Harlin

Harlin,

It should expand (and fill ) in both directions have you checked it's
parents packing options?

That was it Martin. I forgot to expand the parent.

Thanks!

is YES a valid flag for expand?
maybe expand=1

either YES, True, or 1 should work.

yes, indeed.[color=blue][color=green][color=darkred]

True

thanks Harlin,

I hope you also know that

..>> 'inexistent keyword' and 'YES' in dir(Tkconstants )

is also True...

yeah, known but forgotten.

hmmm .......
let's try :
[color=blue][color=green][color=darkred]
>>> import Tkconstants
>>> 'YES' in dir(Tkconstants )[/color][/color][/color]
True[color=blue][color=green][color=darkred]
>>> 'True' in dir(Tkconstants )[/color][/color][/color]
False[color=blue][color=green][color=darkred]
>>> 'TRUE' in dir(Tkconstants )[/color][/color][/color]
True[color=blue][color=green][color=darkred]
>>> ('inexistent keyword') in dir(Tkconstants )[/color][/color][/color]
False

so[color=blue][color=green][color=darkred]
>>> 'TRUE' and 'YES' in dir(Tkconstants )[/color][/color][/color]
True[color=blue][color=green][color=darkred]
>>> 'inexistent keyword' and 'YES' in dir(Tkconstants )[/color][/color][/color]
True

i'll recite 42 times truth tables before going to bed.
however i didn't expect the following:
[color=blue][color=green][color=darkred]
>>> 'inexistent keyword' or 'YES' in dir(Tkconstants )[/color][/color][/color]
'inexistent keyword'[color=blue][color=green][color=darkred]
>>> False or 'YES' in dir(Tkconstants )[/color][/color][/color]
True

hmmm...
[color=blue][color=green][color=darkred]
>>> ('inexistent keyword' or 'YES') in dir(Tkconstants )[/color][/color][/color]
False[color=blue][color=green][color=darkred]
>>> (False or 'YES') in dir(Tkconstants )[/color][/color][/color]
True

i'll recite 42 times precedence rules before going to bed.
but now i'm a bit confused by the -in- operator. as:
[color=blue][color=green][color=darkred]
>>> set(['TRUE','YES']).issubset(set( dir(Tkconstants )))[/color][/color][/color]
True

i expected this to be true, but it's not:
[color=blue][color=green][color=darkred]
>>> set(['TRUE','YES']) in set(dir(Tkconst ants))[/color][/color][/color]
False

originaly, i'm thinking to short-cut the following,[color=blue][color=green][color=darkred]
>>> reduce(lambda t,f: t and f, [i in dir(Tkconstants ) for i in[/color][/color][/color]
'YES','inexiste nt keyword'])
False[color=blue][color=green][color=darkred]
>>> reduce(lambda t,f: t and f, [i in dir(Tkconstants ) for i in[/color][/color][/color]
'TRUE','YES'])
True

but that was too short and i miss something!
i do reset my brain somewhere between cell234 and cell241
thanks for reading!

the 'in' operator searches for existance of *elements* in a set, not of
*subsets*. BTW, only a frozenset can be included in a set.

To check for subsets, either use the issubset function, or the '<' operator (I
believe they both call the same code):

..>> set(['TRUE','YES']).issubset(set( dir(Tkconstants )))
True

can be expressed as

..>> set(['TRUE','YES']) < set(dir(Tkconst ants))
True

ah! yes. that's clear now. thanks!
after all:
[color=blue][color=green][color=darkred]
>>> for element in aset:[/color][/color][/color]
print element,

why did i think that 'in' was another different operator?
the test should be then:
[color=blue][color=green][color=darkred]
>>> 'TRUE' in dir(Tkconstants ) and 'YES' in dir(Tkconstants )[/color][/color][/color]
True

and then:
[color=blue][color=green][color=darkred]
>>> 'inexistent keyword' in dir(Tkconstants ) and 'YES' in[/color][/color][/color]
dir(Tkconstants )
False

a bit cumbersome if there is a lot of keys to test.
i also found in the itertools-recipes the way to avoid
the reduce-lambda construction i had previously in head:
[color=blue][color=green][color=darkred]
>>> from itertools import *
>>> def all(seq, pred=bool):[/color][/color][/color]
"Returns True if pred(x) is True for every element in the
iterable"
for elem in ifilterfalse(pr ed, seq):
return False
return True
[color=blue][color=green][color=darkred]
>>> all(i in dir(Tkconstants ) for i in ['TRUE', 'YES'])[/color][/color][/color]
True[color=blue][color=green][color=darkred]
>>> all(i in dir(Tkconstants ) for i in ['TRUE', 'YES', 'inexistent[/color][/color][/color]
key'])
False

lovely...
i do not regret the fate of reduce et al.
