/home/px/scripts/nitpick.py:157: GtkWarning: Attempting to add a widget with type GtkVBox to a GtkWindow, but as a GtkBin subclass a GtkWindow can only contain one widget at a time; it already contains a widget of type GtkScrolledWindow

私はOOPに非常に慣れていないので、ご容赦ください。ここには 3 つのオブジェクトが必要です: gtk.TreeView、gtk.Menu、およびトップレベルのgtk.Window。右 ？
- 3 つの要素を分離し、最初の 2 つを最後の要素に入れるにはどうすればよいですか?
- なぜ
vbox.pack_start(self.scrolledwindow, False)明らかに機能していないのですか？
