ruby - 红宝石鞋悬停元素

Question

悬停元素不起作用。问题出在哪里？怎么修？

Shoes.app :width => 635, :height => 410 do
    background image "http://PATH_TO_IMAGE"
    a = stack :width => 360, :height => 200, :margin_left => 250, :margin_top => 200 do
        hover do
            a.clear { para "Some Text qwe qwe qwerty", :stroke => black }
        end
        leave do
            a.clear { background image "http://PATH_TO_IMAGE" }
        end
    end
end

我认为原则上您不能image用作background.

我也不确定这是否是您想要达到的效果，但它表明您做错了什么：

Shoes.app :width => 635, :height => 410 do

  a = stack :width => 360, :height => 200  do
    image "http://PATH_TO_IMAGE"

    hover do
         a.clear {para "Some Text qwe qwe qwerty", :stroke => black }
    end

    leave do
        a.clear {  image "http://PATH_TO_IMAGE" }
    end

  end

end
