我正在使用PyGObject,我成功设置了TreeStore和相应的TreeView。这只是一个简单的单列视图。它将所有帐户列为父项,然后您可以单击小三角形并显示文件夹。代码如下所示:
accounts_tree_store = Gtk.TreeStore(str)
treeview_accounts = self.builder.get_object("treeview_accounts")
treeview_accounts.set_model(accounts_tree_store)
renderer = Gtk.CellRendererText()
account_iter = accounts_tree_store.append(None, ["Account1"])
accounts_tree_store.append(account_iter, ["Folder1"])
accounts_tree_store.append(account_iter, ["Folder2"])
accounts_tree_store.append(account_iter, ["Folder3"])
accounts_tree_store.append(account_iter, ["Folder4"])
accounts_tree_store.append(account_iter, ["Folder5"])
然后我添加了这个,所以我可以选择:
selected_tree = treeview_accounts.get_selection()
selected_tree.connect("changed", Handler().on_tree_select_change)
我的函数处理程序如下所示:
def on_tree_select_change(self, widget, *args):
model, iter = widget.get_selected()
if iter:
print((model[iter][0]))
现在这一切都很好。但我想打印出所选元素的父级。类似于:“Account4 for Folder4”。问题是:我如何访问父母?有某种“get_parent()”函数吗?我没有在文档中找到任何内容。有谁知道如何做到这一点?
提前致谢!!
答案 0 :(得分:1)
此功能称为iter_parent,如果iter
有一个,则会返回父级。这是model
的方法。
model, iter = widget.get_selected()
parent = model.iter_parent (iter)
