Pyside will also do that. Won't let the user enter anything but
numbers it you want. But it might be an overkill learning curve
if you only need it for this case.

I would probably just wrap the nuke.getInput call to validate the
string as a number and cast it on return.
import re
def getNumericInput():
while True:
raw = nuke.getInput('Enter a number:')
if raw is None:
return
if re.match('^\d+$', raw):
return int(raw)
nuke.message('Not a valid number')
Obviously this only handles ints, but if you need a float, you
can massage the regex a little.
Hope this helps.

Subject: Re: [Nuke-python] query a number from the user
Well, I wasn't in front of the computer before, and seems like
there isn't a number only knob to inherit for the panel object.
I tried this:
p = nuke.Panel( 'how many dudes?' )
p.addExpressionInput('dudes', '')
p.show()
result = p.value('dudes')
print p.value('dudes')
And it works, but you can type anything in there. Not just a
number.
Anybody knows a knob that only expects numbers?

Hiya.
I Am looking for the way the get a pop up window asking me a
value.
I cheated by using
val = int(nuke.getInput('enter the ref frame'))
wich is normally a text box
is there a better way for numbers ? I mean that will warn if
something else than a number is entered
cheers
