AttributeError: 'gi.repository.Gtk' object has no attribute 'GenericTreeModel'
“GenericTreeModel”已经更名了吗?
谢谢!
PyGObject最近通过pygtkcompat获得了GenericTreeModel支持。
因此,现在您应该能够使用兼容模块迁移GenericTreeModels,至少作为一个开始。
我已经应对这个问题有一段时间了,以下是我的结果:
As Havok already said: the GenericTreeModel
does not exist anymore and one has to use the normal gtk.TreeModel
interface and override the appropriate methods (naming them do_…
):
class TreeModel(GObject.GObject, gtk.TreeModel):
def do_get_iter(self, iter, path):
…
iter.user_data = whatever()
return True
Inheriting from ListStore or TreeStore does not work when using custom iters etc.
The repository with call information is broken (see launchpad:gtk3#1024492) so that the do_get_iter method is called without the iter argument, so you cannot set custom data on it.
To fix it change the direction for the iter
argument in /usr/share/gir-1.0/Gtk-3.0.gir
from "out"
to "in"
and run:
g-ir-compiler --output=/usr/lib/girepository-1.0/Gtk-3.0.typelib /usr/share/gir-1.0/Gtk-3.0.gir
我在PyGObject和Gtk中都找不到GenericTreeModel的任何参考资料,但我认为你要找的只是TreeModel:
http://developer.gnome.org/gtk3/stable/GtkTreeModel.html
TreeModel是一个接口,由ListStore、TreeModelFilter、TreeModelSort和TreeStore实现。

编辑:
在旧的PyGtk API中找到了你要找的内容,不幸的是,这是一个仅限于PyGtk的创作。使用introspection只能获得Gtk直接提供的内容,因此您需要直接处理TreeModel。
希望有所帮助。
