python - 如何设置 Gtk.FileChooserWidget 的默认打开路径？

Question

如果我通过 Gtk.FileChooserWidget.set_current_folder() 方法设置当前文件夹，我第一次打开文件选择器时，它会在用作 set_current_folder( )

但是，如果我选择一个文件，我会重新打开文件选择器，它会在“most_recent_used_files”上打开。

我希望它在最后选择的文件的文件夹路径中打开。

怎么做？

谢谢。

来自文档:

Old versions of the file chooser's documentation suggested using gtk_file_chooser_set_current_folder() in various situations, with the intention of letting the application suggest a reasonable default folder. This is no longer considered to be a good policy, as now the file chooser is able to make good suggestions on its own. In general, you should only cause the file chooser to show a specific folder when it is appropriate to use gtk_file_chooser_set_filename() - i.e. when you are doing a File/Save As command and you already have a file saved somewhere.
