Glade作为GTK3 3/4/5(而不是Gnome-Builder)的起点

Question

现在已经花了一些时间来处理Gnome、Glade、Vala和Genie --并且考虑到优秀的Gnome人机界面准则(GHIG) --为什么Glade不是几乎所有GTK GUI应用程序的起点呢？

例如，是否有任何程序将采用Glade (模板) xml文件并自动生成相应的编程Vala或Genie源代码？例如，如果有标准的GHIG Glade xml文件，而GHIG是随Glade/Gnome一起提供的，那么这些文件可以很快地适应于特定的项目和带有信号自动生成的Genie类模板，再加上完整的gresource/meson/flatpak结构。这只是直接导入作为起点。有做过这样的事吗？

更新

下面的文件application.gs是使用Genie属性组合从application.ui自动生成的。我不想在这里重新发明轮子--这就是提出这个问题的原因。下面删除了一些字段，但是实际的文件已经完全完成，可以使用了。除了“application.ui”的内容之外，唯一需要的信息是资源路径和ui文件名。所有内容都已包含在Glade文件中。

/*
  {PROJECT_SPACE}

  '{PROJECT_NAME}' is a command line tool that will parse a glade ui
  template and generate a skeleton class in the Genie language
  with composite widgets. It will generate GTKTemplate, GTKChild
  and GTKCallback entries.

  '{PROJECT_NAME}' exists within the {PROJECT_NAMESPACE} namespace.

例如，是否有任何程序将采用Glade (模板) xml文件并自动生成相应的编程Vala或Genie源代码？

休想。Glade曾经有一个嵌入式特性，可以生成相应的代码来创建UI。这被删除是有一个很好的原因的:它使应用程序代码不可维护，因为您手动修改生成的代码，如果您想要更改UI，则必须重新生成源代码并解决所有冲突。

现在，使用Glade生成的UI文件是使用GtkBuilder的几行代码。不过，我同意在您的代码中插入具有正确签名的回调将是一个好处。也许侏儒生成器计划这么做？您可能需要检查GNOME Builder developper博客。
