Question

我已将此作为我的代码

 openAll = File.open('N:\Josh\Blondie\db.txt')
 allNumbers = Array.new
 allNumbers=[]  
  openAll.each_line {|line|
    allNumbers.push line
  }

  puts allNumbers

我希望能够在Ruby Shoes的新窗口中显示此代码的输出，但我似乎无法显示任何内容。该文件的内容是姓名和电话号码。

有什么想法吗？

Answer 1

以下是将文字输出到鞋子窗口的示例。使用puts语句只输出到shell，而不是Shoes应用程序。

Shoes.app :title => "GUI RAW file converter, for the CLI challenged", 
  :resizable => true do 
  background white 
  stack do 
    flow {
      background gray, :height => 30
      caption "Caption", :margin => 8, :stroke => white
      stack {
        para 'This is a fancy line I just printed to the window'
####### Here's an example line you could use to put out the array...
        allNumbers.each do |number|
          para "#{number}"
        end
      }
    }
  end
end

Answer 2

我猜你应该使用方法Kernel＃alert而不是Kernel＃puts。
