Question

我正在尝试使用以下示例来创建带有复选框的QComboBox http://programmingexamples.net/wiki/Qt/ModelView/ComboBoxOfCheckBoxes

唯一的区别是QComboBox是可编辑的。当选中/取消选中复选框时，我想用空格分隔的选项文本更新QComboBox文本。

例如，如果＆＃34; item1＆＃34; ＆安培; ＆＃34;项目3＆＃34;检查后，QComboBox文本将更新为＆＃34; item1 item3＆＃34;

我这样做是通过将示例中的:: slot_changed（）的实现更改为以下

import requests

session = requests.Session()
session.proxies = {'http':'socks5://127.0.0.1:9050'}
response = session.get('http://www.icanhazip.com', timeout=2)
print(response.text)

除非我选中/取消选中＆＃34; item1＆＃34;，否则这似乎很有效。组合框文本仅显示＆＃34; item1＆＃34;即使其他人被检查。

这是一个具体的例子
