Here is the implementation of gtk_tree_item_get_subtree:
static PyObject *_wrap_gtk_tree_item_get_subtree(PyObject *self, PyObject *args)
{
PyObject *obj;
if (!PyArg_ParseTuple(args, "O!:gtk_tree_item_get_subtree", &PyGtk_Type, &ob
j))
return NULL;
return PyGtk_New((GtkObject *)GTK_TREE_ITEM(PyGtk_Get(obj))->subtree);
}
The function is just an accessor for the subtree attribute. Of course,
this has some problems if the tree item doesn't have a subtree, which will
have to be fixed for the next release.
James.
