Missing output of togglebuttons about interact.jl HOT 5 CLOSED

Lift instantiates a new ToggleButtons with its own signal each time the first toggle button updates, so you will have to create a signal and have the toggle buttons update that.

ff = ["F1","F2","F3","F4"]
f1 = togglebuttons(ff)
f1_inp = Input("F2")  # This is what f2 will update.
display(f1)
f2 = lift(x->togglebuttons(signal=f1_inp, filter(a->a!=x,ff)),f1)
display(f2)
display(signal(f1))
display(f1_inp)

Should help you.

I'm not entirely sure why when I select F3 in the first set, I get the ordering F1, F4, F2. Will look into this.

i tried your suggested solution, but didn't work either.

from interact.jl.

Could you be more specific about what happens when you run the code? It works for me. Also which browser are you using? Do togglebuttons generally update like they should?

from interact.jl.

i am using Julia-0.4-dev on x64 win7 with Chrome(37.0.2062.103 m)

• Gadfly 0.3.7
• IJulia 0.1.15
• Interact 0.1.4

it's behave the same way i posted originally. second togglebuttons updated, but in strange order, and also cann't output F1.

from interact.jl.

This works on master:

using Interact
ff = ["F1","F2","F3","F4"]
f1 = togglebuttons(ff)
f1_inp = Signal("F2")
f2 = map(signal(f1)) do x
    togglebuttons(filter(a->a!=x, ff); signal=f1_inp)
end
display.([f1, f2, signal(f1), f1_inp]);

The ordering is a bug in ipywidgets, would be good if you can report it there, Python code:

from IPython.display import display
from ipywidgets import ToggleButtons
tb = ToggleButtons()
tb.options = [1,2,3]
display(tb)
tb.options = [0,1,2]

The order should be 0,1,2
