我不确定我是否应该打个招呼,这是我在这里的第一篇文章。
无论如何,我正在关注gtk2hs 网站上的 glade 教程。代码编译正确,但是当我尝试执行它时出现此错误。
(hellogtk2hs:8670): libglade-WARNING **: Expected <glade-interface>. Got <interface>.
(hellogtk2hs:8670): libglade-WARNING **: did not finish in PARSER_FINISH state
hellogtk2hs: user error (Pattern match failure in do expression at HelloGtk2Hs.hs:8:8-15)
这是我的林间空地文件。

林间空地文件与我的源代码位于同一目录中。源代码与教程中的源代码完全相同。我以前从未与 glade 合作过,所以我不知道出了什么问题。
我不得不将 ghc 从 7.6 降级到 7.4.2。我正在使用 glade 3.14.1,所有其他软件包都是通过 cabal 安装的,因此它们使用的是当前版本。
如果我用glade-interface切换界面,在开始和结束时它仍然会抱怨。
(hellogtk2hs:9636): libglade-WARNING **: Unexpected element <object> inside <glade-interface>.
hellogtk2hs: user error (glade.xmlGetWidget: no object named "window1" in the glade file)
如果用小部件更改所有对象标签,我会得到这个
(hellogtk2hs:9668): GLib-GObject-ERROR **: cannot create instance of abstract (non-instantiatable) type `GtkBox'
`trap' para punto de parada/seguimiento
这样做我得到的错误更少,但它仍然不起作用。
