ruby - Ruby Shoes - 子窗格窗口中的滚动条

Question

我似乎无法让滚动条在内部堆栈/流中工作。有谁知道怎么做？

Answer 1

只需固定高度并添加 ":scroll => true" 参数：

Shoes.app(:title => "Scrolll!" ) do
  flow :margin => 10 do
    stack :width => "150px", :height => "200px", :scroll => true do
      para  "all you need is love",  "all you need is love", "all you need is love", "all you need is love", "all you need is love", "all you need is love", "all you need is love", "all you need is love", "all you need is love", "all you need is love",
    end
  end
end

Answer 2

You can use a <div> tag, and then have CSS as such:

#my_div {
 width: [some_width]px;
 height: [some_height]px;
 overflow: auto;
}

Answer 3

我不确定您所说的“内部堆栈/流”到底是什么意思，但我们将 iframe 用于我们的子窗格窗口，它具有您可以设置的滚动属性。否则，您可以使用 YUI 之类的 javascript 框架来获取允许滚动功能的子窗格窗口。
