The Shoes Manual

Radio

So, how do you decide when to use radio buttons and when to use list boxes? Well, list boxes only show one highlighted item unless you click on the box and the drop-down appears. But radio buttons are all shown, regardless of which is marked.

 Shoes.app do
   para "Among these films, which do you prefer?\n"
   radio; para strong("The Taste of Tea"), " by Katsuhito Ishii\n"
   radio; para strong("Kin-Dza-Dza"), " by Georgi Danelia\n"
   radio; para strong("Children of Heaven"), " by Majid Majidi\n"
 end

Only one of these three radios can be checked at a time, since they are grouped together in the same slot (along with a bunch of para.)

If we move them each into their own slot, the example breaks.

 Shoes.app do
   stack do
     para "Among these films, which do you prefer?"
     flow { radio; para "The Taste of Tea by Katsuhito Ishii" }
     flow { radio; para "Kin-Dza-Dza by Georgi Danelia" }
     flow { radio; para "Children of Heaven by Majid Majidi" }
   end
 end

This can be fixed, though. You can group together radios from different slots, you just have to give them all the same group name.

Here, let's group all these radios in the :films group.

 Shoes.app do
   stack do
     para "Among these films, which do you prefer?"
     flow do
       radio :films
       para "The Taste of Tea by Katsuhito Ishii"
     end
     flow do
       radio :films
       para "Kin-Dza-Dza by Georgi Danelia"
     end
     flow do
       radio :films
       para "Children of Heaven by Majid Majidi"
     end
   end
 end
