Ruby green_shoes流

Question

系统设置

Windows 10 Education Edition 64bit
Ruby 2.3.0
green_shoes installed via gem install green_shoes

我对绿色鞋子和红宝石一般都很陌生。我正试图为我的经济学课编写一个简单的真实收入计算器，却遇到了麻烦。

我编写的代码可以正常安装鞋，但我想使用宝石版本，所以我选择了green_shoes，这似乎是最好的。

我遇到的问题是，分段对象应该显示在edit_line对象的左侧，如

准Edit_Line

但是却显示出

第2段

Edit_Line

我不知道我做错了什么，但如果有人能帮忙，那就太棒了。

require 'green_shoes'
Shoes.app(title: "Real Income Calculator", width: 400, height: 180) do
    stack do
        para "Real Income Calculator"
        flow do
            @nip = para "Nominal Income"
            @nip.style(margin_right: 10)
            @nit = edit_line
            @nit.style(width: 150)
        end
        flow do
            @cpip = para "CPI"
            @cpip.style(margin_right: 10)
            @cpit = edit_line
            @cpit.style(width: 80)
        end
        @calc = button "Calculate"
        @calc.click do
            ni = @nit.text.to_i
            cpi = @cpit.text.to_i
            ri = (ni/cpi)*100
            alert(ri)
        end
    end
end

我在green_shoes手册页shoes/Check.html中对此进行建模的代码

Shoes.app do
  stack do
    flow do
      check; para "Frances Johnson", width: 200
    end
    flow do
      check; para "Ignatius J. Reilly", width: 200
    end
    flow do
      check
      para "Winston Niles Rumfoord", width: 200
    end
  end 
end

Answer 1

也许您应该“升级”到Shoes3.3.1或Shoes4 (下面是3.3.1测试的，在Shoes4上也可以)

Shoes.app title: "Real Income Calculator", width: 400, height: 180 do
    stack do
        para "Real Income Calculator"
        flow do
            @nip = para "Nominal Income", margin_right: 10
            @nit = edit_line "", width: 150
        end
    end
end
