I just spent some time thinking about how to specify layouts for
interact controls. Here's a possible syntax:
@interact(layout=[['a','b'],['c','d']])
def _(a=1,b=(2,3),c="hi",d=x+1):
print a,b,c,d
This would lay out a table with a and b in the same row, then c and d in
the same row.
More generally, we can use templates (jinja2?) and html:
@interact(layout="""
some template code, containing variables a, b, c, d, that are each set
to the html representation of the control
""")
def _(a=1,b=(2,3),c="hi",d=x+1):
print a,b,c,d
What do people think? I think these changes would be fairly easy to
implement, and would be backwards-compatible with what we have now.
Another option would be having the layout a parameter of the actual
function:
@interact
def _(a=1,b=(2,3),c="hi",d=x+1, layout="""
some template code, containing variables a, b, c, d, that are each set
to the html representation of the control
""")):
print a,b,c,d
Or we could do things more like mathematica does, and let you just
specify the layout when you specify the variables:
@interact
def _(row(('a',1),('b',(2,3))),row(['c',"hi"],['d',x+1])):
print a,b,c,d
or something. This sort of obscures the variables you are using,
though, and makes it hard to change layouts; it greatly confuses the
content and presentation. It also makes it difficult to use the
function outside of interacts, whereas separately specifying the layout
as above makes it easy to use the function outside of the interact
framework.
Thanks,
Jason
