我正在努力将一些 Gedit 2 插件移植到 Gedit 3 中，但我遇到了错误，不知'Document' object has no attribute 'get_uri'道出了什么问题。对于它的价值，插件的 Gedit 2 版本有效。
def view_result(self, widget):
# Get the selection object
tree_selection = self.results_list.get_selection()
# Get the model and iterator for the row selected
(model, iterator) = tree_selection.get_selected()
if (iterator):
# Get the absolute path of the file
absolute_path = model.get_value(iterator, 3)
# Get the line number
line_number = int(model.get_value(iterator, 2)) - 1
# Get all open tabs
documents = self.window.get_documents()
# Loop through the tabs until we find which one matches the file
# If we don't find it, we'll create it in a new tab afterwards.
for each in documents:
# This is the line throwing the error:
if (each.get_uri().replace("file://", "") == absolute_path):
# This sets the active tab to "each"
(self.window.set_active_tab
(Gedit.tab_get_from_document(each)))
each.goto_line(line_number)
# Get the bounds of the document
(start, end) = each.get_bounds()
self.window.get_active_view().scroll_to_iter(end, 0.0)
x = each.get_iter_at_line_offset(line_number, 0)
self.window.get_active_view().scroll_to_iter(x, 0.0)
return
# If we got this far, then we didn't find the file open in a tab.
# Thus, we'll want to go ahead and open it...
self.window.create_tab_from_uri("file://" + absolute_path,
self.encoding, int(model.get_value(iterator, 2)), False, True)
此外，我的文件中有以下导入行：
from gi.repository import Gtk, Gio, GObject, Gedit
import os
我已经尝试在我已经拥有的 Gedit 3 插件中查找类似的行，以查看是否有更改，但是它们具有相同类型的代码，并且搜索 Google 和 StackOverflow 都没有给我任何我可以使用的东西。我是 Python 的新手，这样做是为了学习它，所以我可能会遗漏一些完全明显的东西，但它是什么？
编辑 print each, type(each), dir(each)产生以下内容：
