notebook interact -- make it so one control can depend on others

[williamstein]

I really like the @interact functionality! I'm trying to do something
like this:

@interact
def _(p=5,q=range(p)):
   ...

So I'd like the range of q to depend on the current value of p. This
doesn't seem to be possible. Is there any way to make it work?

Here is another request from sage-support which seems very similar.

I want to know if there is any way to "create" new buttons while
already in execution.

This is a testing code i wrote (of course, just for testing
purposes :P)

@interact 
def _(n1=input_box(0,label='Testing', type=int),a=selector([1,2,7], 
buttons=True), n2=input_box(1,label='Testing2',type=int), 
juega=input_box(0,label='Testing3',type=int)): 
    if(n1>0): 
        print 'hi' 
        another_function() 
def another_function(t1=input_box(0,label='Testing123')): 
    print 'hola' 

Thing is, when i run it, i can get it to print 'Hola' but no input_box
is created again. I've managed to "make" one using html, but i can't
get to "interact" with it.

What i'm thinking on doing is a program that has several options using
a selector, e.g. if you choose 1 then it should appear a grid so that
when u enter matrix values it does some calcs, if you choose 2 then it
should appear an input box, and so on...

Turns out that this is going to be available once it makes its way back from the single-cell server code! See this ask.sagemath.org question, in particular Jason's answer.

This can be done in Jupyter, using traitlets links.
