代码解析:
使用Gtk.Builder加载主界面文件shortcuts.glade.
有一个注意的事项就是下面这句话

<signal name="clicked" handler="builder_shortcuts" swapped="1" object="window1"/>

意思相当于

button.connect_object("clicked",self.builder_shortcuts,window1)

回调函数的第一个参数不是button，而是window1

所以在show_shortcuts（)方法中使用
overlay.set_transient_for(window)来设置overlay的父窗口

另一个注意的事情就是view_name属性的使用

overlay.props.view_name = view

表示用来显示view_name为view的视图，其他的不予显示。
