Ruby + Tk 的 canvas 和形状有问题

Ruby + Tk's canvas and shapes are bugging out

我正在 运行ning Windows + Ruby2.3 并且正在弄乱 tk 库。我试图让它绘制一个由不同颜色的矩形组成的网格,但每当我尝试向 canvas 添加形状时,我的脚本就会崩溃。这是代码的精简版本:

require 'tk'
require 'tkextlib/tile'
root = TkRoot.new
content = Tk::Tile::Frame.new(root)
canvas = TkCanvas.new(content)
line = TkcLine.new( canvas, 0, 0, 10, 10, :fill => 'red' )
Tk.mainloop

然而,当我 运行 它时,我得到以下错误 + 回溯:

C:/Ruby23/lib/ruby/2.3.0/tk/itemconfig.rb:115:in `hash_kv': wrong argument type nil (expected Array) (TypeError)
        from C:/Ruby23/lib/ruby/2.3.0/tk/itemconfig.rb:115:in `itemconfig_hash_kv'
        from C:/Ruby23/lib/ruby/2.3.0/tk/canvas.rb:722:in `_parse_create_args'
        from C:/Ruby23/lib/ruby/2.3.0/tk/canvas.rb:735:in `create'
        from C:/Ruby23/lib/ruby/2.3.0/tk/canvas.rb:758:in `create_self'
        from C:/Ruby23/lib/ruby/2.3.0/tk/canvas.rb:751:in `initialize'
        from C:/nopathforyou.rb:9:in `new'
        from C:/nopathforyou.rb:9:in `<main>'

有人知道该怎么办吗?提前致谢。

我遇到了同样的错误,最后我通过添加下面的代码解决了这个问题:

module TkItemConfigOptkeys
    def itemconfig_hash_kv(id, keys, enc_mode = [], conf = [])
        hash_kv(__conv_item_keyonly_opts(id, keys), enc_mode, conf)
    end
end

它应该在 'require' 语句之后,比如说,你的代码应该是这样的:

require 'tk'
require 'tkextlib/tile'
module TkItemConfigOptkeys
  def itemconfig_hash_kv(id, keys, enc_mode = [], conf = [])
    hash_kv(__conv_item_keyonly_opts(id, keys), enc_mode, conf)
  end
end
root = TkRoot.new
content = Tk::Tile::Frame.new(root)
canvas = TkCanvas.new(content)
line = TkcLine.new( canvas, 0, 0, 10, 10, :fill => 'red' )
Tk.mainloop

添加之后,我的代码运行得非常棒。

Ruby/Tk 已在 this commit 中修复此错误。

所以您可以只更新您的 tk 库,作为替代。
