我正在尝试用python 2.7制作一个小的GTK 3 irc客户端。目前，我有一个非常基本的客户端，可以成功连接到irc网络并在主文本区域中显示一些内容。我目前正在尝试实现多渠道支持，但是在加入渠道时用包含该渠道的条目填充GtkListBox似乎不起作用。
python代码如下：

self.log("* %s %s" % (user, msg))
# irc callbacks
def irc_NICK(self, prefix, params):
"""Called when an IRC user changes their nickname."""
old_nick = prefix.split('!')[0]
new_nick = params[0]
self.log("%s is now known as %s" % (old_nick, new_nick))

# collisions. The default method appends an underscore.

据我所知，添加到GtkListBox的代码将在窗口中运行，但在扭曲的ircclient类中则无效。
任何帮助表示赞赏！
最佳答案
原来只是一种情况，我需要调用row.show_all()以便将listboxitem显示在UI中
关于python - 无法将项目添加到我的Gtk.Window之外的GtkListBox中，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/28388886/
