Progress

Progress bars show you how far along you are in an activity. Usually, a progress bar represents a percentage (from 0% to 100%.) Shoes thinks of progress in terms of the decimal numbers 0.0 to 1.0.

A simple progress bar is 200 pixels wide, but you can use the :width style (as with all Shoes elements) to lengthen it.

 Shoes.app do
   stack margin: 0.1 do
     title "Progress example"
     @p = progress width: 1.0
     animate do |i|
       @p.fraction = (i % 100) / 100.0
     end
   end
 end

Take a look at the Common methods page for a list of methods found an all elements, including progress bars.

fraction() ยป a decimal number
