PythonGTK+3:通过单击列对树视图进行排序
问题描述
我希望能够通过单击列来按列对树视图进行排序。我只是引用文档中的流行示例作为参考(https://python-gtk-3-tutorial.readthedocs.io/en/latest/treeview.html): self.treeview = Gtk.TreeView.new_with_model(self.filter)
for i, column_title in enumerate(["one", "two", "three", "four", "five", "six", "seven", "eight", "nine", "ten", "eleven", "twelve"]):
renderer = Gtk.CellRendererText()
column = Gtk.TreeViewColumn(column_title, renderer, text=i)
self.treeview.append_column(column)
column.set_sort_column_id(i)
除非我收到错误:
(test.py:26081):gtk-Critical**:12:35:03.856:gtk_tree_sortable_get_sortable_Column_id:断言‘gtk_is_tree_sortable(Sortable)’失败
(test.py:26081):gtk-关键**:12:35:03.856:gtk_TREE_SOLTABLE_HAS_DEFAULT_SORT_FUNC:断言‘GTK_IS_TREE_SOLTABLE(SOLTABLE)’失败
(test.py:26081):gtk-Critical**:12:35:03.856:gtk_tree_sortable_set_ort_Column_id:断言‘gtk_is_tree_sortable(Sortable)’失败
解决方案
在this post的帮助下,我想出了一个方法。
编辑以下行:
self.treeview = Gtk.TreeView.new_with_model(self.filter)
在
self.treeview = Gtk.TreeView.new_with_model(Gtk.TreeModelSort(self.filter))
并且应该可以工作。
